Abstract
Description
本発明は、植物に対するストレスの緩和および植物の生長促進に関する。 The present invention relates to alleviating stress on plants and promoting plant growth.
現代農業においては、生産性向上のために化成肥料が多用され、その結果、植物体に吸収されなかった塩類が土壌に蓄積する。特に施設園芸においては、連作が原因で塩蓄積がより顕著である。また、耕地拡張のため、干拓も盛んに行われてきたが、そのような土地では海水由来の塩化ナトリウムが土壌に高濃度で存在する。また、干拓地ではない耕地でも、海岸地帯では地下水にナトリウムイオンを高濃度で含む場合が多い。これらの状態はいずれも栽培植物に対して高塩濃度によるストレス（塩ストレス）を与えている。かかる塩ストレスを緩和するために種々の措置が行なわれている。例えば天地返し、表土補充などが行われている。しかしながらこれらの措置は一時凌ぎに過ぎず根本的な解決法にはならない。弱耐塩性植物の幼植物体に対しベタイン類または糖アルコール類を適合溶質として供給する方法が開示されている（特許文献１）が、その効果は幼植物段階迄しか示されておらず、最終的な収量への効果は不明である。コリンオキシダーゼをコードする遺伝子を含有する組換えベクターで植物を形質転換し、耐塩性、耐浸透圧性植物を作出する方法も開示されている（特許文献２）が、その実施例においては形質転換植物の耐塩性獲得までが示されるだけで、生産性向上に寄与したかは明らかではない上、組換体植物の栽培について厳しく制限されている現状においては、実用性に欠ける。 In modern agriculture, chemical fertilizers are frequently used to improve productivity, and as a result, salts that have not been absorbed by plants accumulate in the soil. Especially in greenhouse horticulture, salt accumulation is more prominent due to continuous cropping. In addition, cultivating land has been actively reclaimed, but in such land, sodium chloride derived from seawater is present in soil at high concentrations. Moreover, even in arable land that is not reclaimed land, coastal water often contains high concentrations of sodium ions in groundwater. All of these states give stress (salt stress) due to high salt concentration to cultivated plants. Various measures have been taken to relieve such salt stress. For example, top-and-bottom return and topsoil replenishment are performed. However, these measures are only temporary surrogates and are not a fundamental solution. A method of supplying betaines or sugar alcohols as compatible solutes to seedlings of weakly salt tolerant plants is disclosed (Patent Document 1), but the effect has been shown only up to the stage of seedlings. The effect on overall yield is unknown. A method for producing a salt-tolerant and osmotic-resistant plant by transforming a plant with a recombinant vector containing a gene encoding choline oxidase is also disclosed (Patent Document 2). It is not clear whether it has contributed to the improvement of productivity by only showing the acquisition of salt tolerance, and in the current situation where the cultivation of recombinant plants is severely restricted, it lacks practicality.
また、露地栽培においては本来一定時期にしか開花・収穫されない植物を施設栽培により通年収穫することが極一般的に行われるが、限られた空間内で栽培を行うため、温湿度が急変しやすく、植物体はしばしばストレス（温度ストレス、乾燥ストレス、過湿ストレス）に曝される。これらのストレスは多くの障害を植物体に与え、極端な場合は植物体の枯死に繋がる。これらの被害は、適切な温度・灌水管理で軽減されるが、省力化された施設においては、完全な管理は不可能であるのが現状である。 Also, in open-air cultivation, plants that are originally flowered and harvested only at certain times are generally harvested throughout the year by facility cultivation, but because they are cultivated in a limited space, the temperature and humidity are likely to change suddenly. Plant bodies are often exposed to stress (temperature stress, drought stress, excessive humidity stress). These stresses cause many damages to plants and, in extreme cases, lead to the death of plants. These damages can be mitigated by appropriate temperature and irrigation management, but it is currently impossible to manage completely in labor-saving facilities.
また農業においては、栽培期間の短縮、増収、品質向上は、あまねく収益増に結びつくため、永遠に追究され続ける目標である。短期的には各種肥料の施用により目標を達することも可能ではあるが、上記の通り多肥栽培の結果、塩類が蓄積して土壌を疲弊させ、長期的には、当初目的に逆行する結果に陥る場合が多い。 In agriculture, shortening the cultivation period, increasing sales, and improving quality are the goals that will continue to be pursued forever, as they will generally lead to increased profits. Although it is possible to achieve the goal by applying various fertilizers in the short term, as a result of the multi-fertilization cultivation, as a result of the above, salt accumulates and the soil is exhausted, and in the long term, the result reverses the original purpose. Often falls.

Sugar is measured by HPLC method (resin column: KS-801), amino acids are measured by formol method, organic acids are measured by a method using an organic acid analyzer, and betaine is measured by HPLC method (resin column: KS-801). It is the value.
2003年５月５日に、先端が3mm以上枯れ込んだ葉数を、各鉢毎に調査した。調査結果を表１に示す。 On May 5, 2003, the number of leaves that had withered 3 mm or more in the tip was examined for each pot. The survey results are shown in Table 1.
表１に示す通り、ＣＣＲの施用により、葉先枯れは完全に抑えられた。着蕾数、草丈については、ＣＣＲ施用の影響はなかった。葉先枯れが生じると商品価値が低下するため、通常は出荷前にこれらを除去するが、85鉢/人工程度しか処理できないためコストアップにつながっている。ＣＣＲ施用により、品質向上、コスト削減が実現される。 As shown in Table 1, leaf tip wilt was completely suppressed by application of CCR. There was no effect of CCR application on the number of landings and plant height. When leaf end wilt occurs, the value of the product decreases, so these are usually removed before shipment, but only 85 bowls / artificial can be processed, leading to an increase in cost. By applying CCR, quality improvement and cost reduction are realized.
本実施例では本発明のストレス緩和剤の塩ストレス緩和効果を評価した。植物に対する塩ストレスの影響を緩和する適合溶質としてベタインが知られていることから、本実施例では、糖類、有機酸類、アミノ酸類およびベタイン含有するＣＣＲを施用する処理区のほかに、ベタインのみを単独で施用する処理区を設定して比較を行った。下記実施例５および６についても同様である。 In this example, the salt stress mitigating effect of the stress relieving agent of the present invention was evaluated. Since betaine is known as a compatible solute that alleviates the effects of salt stress on plants, in this example, in addition to the treatment section to which CCR containing saccharides, organic acids, amino acids and betaine is applied, only betaine is added. Comparison was made by setting a treatment section to be applied alone. The same applies to Examples 5 and 6 below.
灌水に使用している地下水にナトリウムイオンが50〜60ppm含まれるため、ナトリウム蓄積の悪影響を受けやすい条件下で栽培されているシンビジウム（品種：ピンクヴェイル‘ラブ’）の２年後開花見込株を供試した。2003年１月26日に、５号素焼鉢に20株ずつ水苔植にて寄せ植えにされていたものから水苔を取り除いた。1)製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）を地下水で1,000倍に希釈した液、2)ベタイン0.008％地下水溶液、3)地下水に、根部を24時間浸漬した。何れの地下水にもナトリウムイオン約50ppmが含まれている。その後、チップ（松皮）を支持材料として３号プラスティック鉢に１株植とし、１週間後にロングトータル花き１号（チッソ旭製）、マルチケーミン（サカタのタネ製）を元肥として施用した。栽培期間中、ナトリウムイオンを約50ppm含む地下水を灌水し、灌水頻度は慣行法に従った。植え替えの際、ＣＣＲ希釈液に根部を浸漬した株に対し、２００３年５月２日に、ＣＣＲ（固形分55％）を同じ地下水で500倍に希釈した液を１株当たり40ml（ＣＣＲの施用量は固形分として0.044g/株）、葉面散布した。同様に植え替えの際、ベタイン水溶液に根部を浸漬した株に対し同日、ベタイン0.016％水溶液（同じ地下水を使用）を１株当たり40ml（ベタインとして6.4mg/株）を葉面散布した。反復数は、それぞれ50株とした。
２００３年８月２６日に、最大葉長を調査した。調査結果を表２に示す。
Since the groundwater used for irrigation contains 50-60 ppm of sodium ions, the expected flowering line after 2 years of Cymbidium (variety: Pink Vale 'Love') cultivated under conditions that are susceptible to sodium accumulation I tried it. On January 26, 2003, the moss was removed from what was planted together in the No. 5 clay pot by 20 moss plants. 1) Chromatographic waste liquid (CCR manufactured by Nippon Sugar Cane, solid content 55%, same composition as used in Example 1) diluted 1,000 times with ground water, 2) Betaine 0.008% ground water solution 3) The root was immersed in groundwater for 24 hours. All groundwater contains about 50ppm of sodium ions. Then, using a chip (pine bark) as a support material, one plant was planted in a No. 3 plastic pot, and one week later, Long Total Flower No. 1 (manufactured by Chisso Asahi) and Multicamin (manufactured by Sakata Seed) were applied as the original fertilizer. During the cultivation period, groundwater containing about 50 ppm of sodium ions was irrigated, and the frequency of irrigation followed the conventional method. At the time of replanting, on May 2, 2003, 40 ml of CCR (solid content 55%) diluted 500 times with the same ground water was used per strain (CCR of CCR). The application rate was 0.044 g / strain as solid content), and the leaves were sprayed. Similarly, at the time of replanting, 40 ml of betaine 0.016% aqueous solution (using the same groundwater) (6.4 mg / strain as betaine) per leaf was sprayed on the same day to the strains whose roots were immersed in an aqueous solution of betaine. The number of repeats was 50.
On August 26, 2003, the maximum leaf length was investigated. The survey results are shown in Table 2.
表２に示した通り、ＣＣＲ希釈液への根部浸漬および葉面散布により、シンビジウムの生育が促進された。施用したＣＣＲ希釈液に含まれるベタイン濃度相当のベタイン溶液には、そのような効果は認められなかった。 As shown in Table 2, the growth of cymbidium was promoted by root soaking and foliar application in a CCR diluent. Such effects were not observed in the betaine solution corresponding to the betaine concentration contained in the applied CCR dilution.
暖地において盛暑期に育苗すると、高温ストレスのため生存率・苗品質が低下しやすいパンジー（品種：タキイＦ１ナチュレオーシャン）を供試した。2003年７月27日に、200穴トレイへ播種し８月２日までに大半が発芽した。８月９日、16日、23日の３回、1)製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液、または、2)水を底面灌水した。反復数は、トレイ１枚分（各処理前に発芽した170〜180株が対象）とした。 Pansy (variety: Takii F1 Nature Ocean), whose survival rate and seedling quality tend to decrease due to high temperature stress when seedlings were raised in the hot season in warm regions, was used. On July 27, 2003, the seeds were seeded in 200-hole trays, and most of them germinated by August 2. August 9th, 16th, 23rd, 3rd, 1) Chromatographic waste liquid as a by-product of sugar production (CCR manufactured by Nippon Sugar Sugar, 55% solids, having the same composition as used in Example 1) 1,000-fold dilution Liquid or 2) water was irrigated at the bottom. The number of repetitions was one tray (targeting 170-180 strains germinated before each treatment).
８月２９日に枯死率の調査を行い、その他品質面についても調査した。枯死率調査結果を表３に示す。 On August 29th, the death rate was investigated, and other quality aspects were also investigated. Table 3 shows the results of the death rate survey.
表３に示した通り、ＣＣＲ希釈液の底面灌水により枯死する株数が半分以下になった。
また、８月２９日に３号ビニールポットへ移植を行い根の状態を確認したところ、ＣＣＲ施用した株は、根の発達が旺盛であり、特に細根が良く生育していた。
As shown in Table 3, the number of strains that died due to bottom surface irrigation of the CCR dilution decreased to less than half.
Moreover, when the state of the root was confirmed by transplanting to No. 3 vinyl pot on August 29, the CCR-applied strain had strong root development, and fine roots grew particularly well.
移植後の９月２６日に葉数を調査した。調査株数は、ＣＣＲ処理区162株、対照区159株であった。結果を表４に示す。 The number of leaves was examined on September 26 after transplantation. The number of strains surveyed was 162 CCR-treated and 159 control. The results are shown in Table 4.
表４に示した通り、ＣＣＲ施用により鉢上げ後の生育が揃って旺盛になった。対照区では、生育の揃いが悪く、葉数の変動幅が大きかった。 As shown in Table 4, the growth after potting became uniform and vigorous by applying CCR. In the control group, the growth was not uniform and the fluctuation range of the number of leaves was large.
ＣＣＲ施用により葉柄が強固になった。着蕾状況については、ＣＣＲ施用区の株が一定サイズに達するまで着蕾しないのに対し、対照区では十分生育しない時期から着蕾し，更に生育が遅れる傾向があった。 CCR application strengthened the petiole. As for the arrival status, the strain in the CCR application area did not arrive until it reached a certain size, whereas in the control area, it arrived from the time when it did not grow sufficiently, and the growth tended to be delayed.
オリエンタルハイブリッドユリ（品種：シベリア）を供試した。冷凍球根に、2003年８月１日よりプレルーティング処理を開始し、更にルーティング処理を行った。ルーティング処理中の８月17日に、1)製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液、または、2)水を球根60球当たり2,000ml散布した。ＣＣＲの施用量は固形分として0.018g/球に相当する。８月２０日に露地（寒冷紗にて50％遮光）へ定植した。施肥は基肥として有機入り化成肥料（未来科学製、Ｎ：Ｐ：Ｋ＝６：６：５）を球根8,000球当たり50kg施用し、栽培期間中は追肥を行わなかった。定植後、８月30日、９月16日、10月１日の３回、ルーティング処理中に、施用したものと同じ溶液（または水）を１株当たり20ml葉面散布した。葉面散布時のＣＣＲの施用量は散布１回につき固形分として0.011g/株に相当する。各処理区100株を試験対象とし、慣行に従って適期に採花した。 An Oriental hybrid lily (variety: Siberia) was used. Pre-routing processing was started on frozen bulbs from August 1, 2003, and further routing processing was performed. On August 17 during the routing process, 1) Chromatographic waste liquid as a by-product of sugar production (CCR manufactured by Nippon Sugar Sugar, 55% solids, having the same composition as used in Example 1) 2) 2,000 ml of water was sprayed per 60 bulbs. The application rate of CCR corresponds to 0.018 g / sphere as solid content. On August 20th, it was planted in an open field (50% shading in cold weather). As fertilizer, 50 kg of organic fertilizer (N: P: K = 6: 6: 5) was applied as a basic fertilizer per 8,000 bulbs, and no additional fertilization was performed during the cultivation period. After planting, the same solution (or water) as applied was sprayed on the surface of August 30, September 16, and October 1 three times during the routing process. The application rate of CCR at the time of foliar application corresponds to 0.011 g / strain as solid content per application. 100 strains in each treatment area were used as test subjects, and flowers were harvested in a suitable time according to the custom.
定植から採花までの所要日数、地表部からの草丈、着蕾数を測定した。結果を表５に示す。 The number of days required from planting to flowering, the plant height from the surface, and the number of landings were measured. The results are shown in Table 5.
表５に示した通り、ＣＣＲ施用により採花までの所要日数が短縮され、草丈は長くなった。草丈については、ＣＣＲ施用により変動が少なくなった。着蕾数には影響はなかった。 As shown in Table 5, application of CCR shortened the number of days required for flowering and increased plant height. As for the plant height, the fluctuation was reduced by CCR application. There was no effect on the number of arrivals.
トマト（品種：桃太郎ファイト）を、土壌の塩類濃度の指標となる電気伝導度（ＥＣ）が高く塩類集積条件と見なされる隔離ベッド（ＥＣ＝１．５mS/cm）に定植させた、塩ストレス条件下で栽培中のものを供試した。この栽培条件は、収穫初期にカルシウム欠乏による尻腐れ症状が発生しやすい。慣行に従って育苗された苗を２００３年５月１２日に隔離ベッドへ定植した。園試処方0.75倍液を循環させてガラス温室内で管理した。７月５日、１５日の２回、1)製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）500倍希釈液、2)ベタイン0.016％水溶液、3)水、の何れかを100ml/株の割合で葉面散布した。ＣＣＲの施用量は固形分として、0.11g/株、ベタインの施用量は0.016g/株に相当する。その他の栽培管理は慣行法に従った。各処理区50株を試験対象とした。 Salt stress condition in which tomato (variety: Momotaro Fight) was planted in an isolated bed (EC = 1.5 mS / cm), which has high electrical conductivity (EC), which is an index of soil salt concentration, and is regarded as a salt accumulation condition The ones under cultivation were used below. This cultivation condition is likely to cause rot rot due to calcium deficiency in the early harvest. Seedlings grown in accordance with common practice were planted in isolation beds on May 12, 2003. Circulation of 0.75 times of garden trial prescription was circulated and managed in the glass greenhouse. Twice 5th and 15th, 1) Chromatographic waste liquor as a by-product of sugar production (CCR made from Japanese sugar beet sugar, 55% solids, having the same composition as used in Example 1) 500-fold dilution, 2 Any one of a) betaine 0.016% aqueous solution and 3) water was sprayed on the leaves at a rate of 100 ml / strain. The application rate of CCR corresponds to 0.11 g / strain as solid content, and the application rate of betaine corresponds to 0.016 g / strain. Other cultivation management followed the customary law. 50 strains in each treatment area were tested.
７月３１日〜８月４日の期間の収量と、尻腐れ症状の度合いを表６に示した。尻腐れ症状については、病斑の発生率と、発生果実における病斑の長径平均値で表示した。 Table 6 shows the yield of July 31 to August 4 and the degree of hip rot symptoms. The rot rot symptoms were expressed as the incidence of lesions and the average length of lesions in the fruits.
表６に示した通り、ＣＣＲ施用により着花、結実が促進され、収穫開始時期が早まった結果、収穫開始時の収量が多くなった。また、尻腐れ病が発生しやすい条件であったが、ＣＣＲ施用によって発生率が低下し、症状も緩和された。ＣＣＲ希釈液相当のベタイン水溶液では、以上のような効果は認められなかった。 As shown in Table 6, the application of CCR promoted flowering and fruiting, and as a result of the early harvest start time, the yield at the start of harvest increased. Moreover, although it was the conditions on which the bottom rot is easy to generate | occur | produce, the incidence rate fell by CCR application, and the symptom was also relieved. The above effects were not observed in the betaine aqueous solution corresponding to the CCR diluted solution.
塩類集積土壌（ＥＣ＝１．５mS/cm）にて栽培されたミニトマトを供試した。２００３年8月２０日に、ミニトマト（品種：千果）苗を定植し、同年8月28日、9月28日、10月27日の3回、1)製糖副産物であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液、2)ベタイン0.008％水溶液、3)水、の何れかを500ml/株、灌注した。ＣＣＲの施用量は固形分として0.275g/株、ベタインの施用量は0.04g/株に相当する。施肥を含むその他の栽培条件は、慣行法に従った。各処理区10株を試験対象とした。 A cherry tomato cultivated in salt accumulation soil (EC = 1.5 mS / cm) was used. On August 20, 2003, planted cherry tomato (variety: Chika) seedlings three times on August 28, September 28, and October 27 of the same year, 1) Chromatographic waste liquid (Japan) Sugar beet sugar CCR, solid content 55%, having the same composition as used in Example 1, 1,000-fold diluted solution, 2) betaine 0.008% aqueous solution, and 3) water were irrigated at 500 ml / strain. The application rate of CCR corresponds to 0.275 g / strain as solid content, and the application rate of betaine corresponds to 0.04 g / strain. Other cultivation conditions including fertilization followed customary methods. Ten strains in each treatment area were tested.
11月29日に、5個/株の完熟した果実を全株から収穫し、果汁の糖度（レフブリックス、屈折糖度計で測定）を測定した。結果を表７に示した。 On November 29, 5 ripening fruits / strain were harvested from all the strains, and the sugar content (measured with a refbrix and a refractometer) was measured. The results are shown in Table 7.
表７に示した通り、ＣＣＲ施用によりミニトマトの糖度が上昇した。ＣＣＲ希釈液相当のベタイン水溶液では、糖度上昇はごく僅かにとどまった。 As shown in Table 7, the sugar content of cherry tomatoes increased by CCR application. In the betaine aqueous solution equivalent to the CCR dilution, the increase in sugar content was negligible.
塩類蓄積土壌（ＥＣ＝１．５）（同上）に定植し、開花状況が不良であるスターチスを供試した。2002年９月10日に、スターチス（品種：サンデーラベンダー）を、ビニールハウス内の塩類蓄積土壌に定植し、慣行に従って栽培したところ、2003年２月時点で萼が殆ど着色せず、花茎も伸びないため、殆ど採花できない状態であった。このラベンダーに対し、製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液または水を、表８に示した条件で、125ml/株、灌水チューブで施用した（ＣＣＲの施用量は固形分として0.069g/株）。１試験区は100株とした。 A statice with a poor flowering condition was planted in a salt-accumulating soil (EC = 1.5) (same as above). On September 10, 2002, Statice (variety: Sanda Lavender) was planted in salt-accumulating soil in a greenhouse and cultivated according to customary practices. Since there was no flower, it was almost impossible to flower. For this lavender, the chromatographic waste liquid (CCR made from Japanese sugar beet sugar, 55% solids, having the same composition as that used in Example 1) 1,000-fold diluted solution or water was used under the conditions shown in Table 8. Then, 125 ml / strain was applied in an irrigation tube (the amount of CCR applied was 0.069 g / strain as a solid content). One test area was 100 strains.
1)採花開始〜2003年2月24日、2) 2003年2月25日〜2003年4月30日の各期間について、３試験区の採花本数を調査し、結果を表９に示した。 1) From the beginning of flowering to February 24, 2003, 2) For each period from February 25, 2003 to April 30, 2003, the number of flowers in the three test areas was investigated, and the results are shown in Table 9.
表９に示した通り、ＣＣＲ施用により、萼の着色が進みボリュームがアップした結果、採花本数が著しく増加した。ＣＣＲ施用回数については、２回の方が、より効果が認められた。対照区においては、萼の着色は進まず、一部個体が枯死したこともあって大幅に減収した。 As shown in Table 9, as a result of the coloration of the cocoon and the increase in volume due to the application of CCR, the number of flowers collected increased significantly. As for the number of times of CCR application, the effect was recognized more twice. In the control, the coloration of the cocoons did not progress, and sales decreased significantly due to the death of some individuals.
プリムラ マラコイデスを供試した。2003年9月1日に、30cm×40cmの育苗箱に種子をばら蒔きした。その後、プリムラ マラコイデスの生育適温より5〜10度高い気温が続いたため、9月20日に発芽後の生存率を調査したところ、41％が枯死し、生存株も根張りが悪く生育不良であった。9月20日に、育苗箱当たりの株数を40株とし、製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液または水を、育苗箱当たり1,000ml散布した。（ＣＣＲの施用量は、固形分として0.014g/株）。１処理区当たり育苗箱2箱を割り当てた。尚、9月20日以降も、気温はプリムラ マラコイデスの生育適温より約5度高い状態が、10月10日まで続き、その後は生育適温にほぼ近い温度で推移した。 Primula Marakoides was tested. On September 1, 2003, seeds were scattered in a seedling box of 30 cm × 40 cm. After that, because the temperature continued to be 5-10 degrees higher than the optimal temperature for Primula Malacoides, the survival rate after germination was examined on September 20, and 41% died. It was. On September 20th, the number of strains per seedling box was changed to 40, and the chromatographic waste liquid as a by-product of sugar production (CCR manufactured by Nippon Sugar Sugar Co., Ltd., having a solid content of 55% and the same composition used in Example 1) was diluted 1,000 times 1,000 ml of liquid or water was sprayed per nursery box. (The application rate of CCR is 0.014 g / strain as solid content). Two nursery boxes per treatment area were allocated. In addition, after September 20, the temperature was about 5 degrees higher than the optimal temperature for Primula Malacoides, which lasted until October 10 and thereafter remained at a temperature close to the optimal temperature.
10月20日に、生育調査（生存率、最大葉長測定、根長測定）を行った。結果を表１０に示した。 On October 20, a growth survey (survival rate, maximum leaf length measurement, root length measurement) was performed. The results are shown in Table 10.
表１０に示した通り、ＣＣＲ施用により、高温ストレス条件下で栽培中のプリムラ マラコイデスの生存率が上昇し、生育も促進された。ＣＣＲ施用区の株は、中間サイズ（2.5号鉢）を通り越して一気に3.5号鉢へ鉢上げ可能なものが多かったが、対照区ではそのような株はなかった。 As shown in Table 10, the CCR application increased the survival rate of Primula Malacoides during cultivation under high temperature stress conditions, and promoted the growth. Many of the strains in the CCR application zone passed through the intermediate size (No. 2.5 bowl) and could be raised to No. 3.5 bowl at a stretch, but there was no such strain in the control zone.
寒冷地（旭川市）にて低温障害を受けやすい条件で栽培された、ナス（品種：千両）を供試した。2003年５月22日に、基肥としてほう素入り燐硝安加里（NS262、全農製）を200kg/10a施用した耕地へ、本葉が９枚展開した苗を定植した。６月１日、11日、21日の３回、1)製糖副産品であるクロマト廃液（日本甜菜製糖製ＣＣＲ、固形分55％、実施例１に使用したものと同一組成を有する）1,000倍希釈液、または、2)水を200ml/株の割合で灌注した。ＣＣＲの施用量は灌注１回につき固形分として0.11g/株、ベタインは0.016g/株に相当する。試験対象は、各試験区10株とした。
収穫開始より2003年9月15日までの収量合計（１株当たり）を表１１に示した。
Eggplants (variety: 1,000 cars) cultivated in cold regions (Asahikawa City) under conditions susceptible to low temperature damage were used. On May 22, 2003, seedlings with nine true leaves were planted on arable land with 200 kg / 10a of boron-containing phosphoric acid Ankasari (NS262, manufactured by Zenno Nori) as the basic fertilizer. June 1st, 11th, 21st, 3rd, 1) Chromatographic waste liquid as a by-product of sugar production (CCR made by Nippon Sugar Sugar, 55% solids, having the same composition as used in Example 1) 1,000-fold dilution Solution or 2) Water was irrigated at a rate of 200 ml / strain. The application rate of CCR corresponds to 0.11 g / strain as solid content per irrigation, and betaine corresponds to 0.016 g / strain. The test subjects were 10 strains in each test area.
Table 11 shows the total yield (per share) from the start of harvesting until September 15, 2003.
