Abstract
Description
植物は、種子繁殖(有性生殖)または栄養繁殖(無性生殖)を介して、種の繁栄を維持する。植物の育種において、優良な形質を有する個体を多数得ることが求められている。そのために、遺伝的に異なる多数の個体から、目的に合致する優良な個体を選抜し、選抜された個体が栄養繁殖を用いてクローン増殖され、クローン苗が取得される。栄養繁殖は、同一形質の固体を増殖させることができる技術であり、挿し木、接ぎ木、取り木、株分けなどが含まれる。
本発明は、どのような植物に対しても適用することができる。中でも木本植物に適用されることが好ましく、草本植物よりも発根能が劣っている木本植物に適用されることが、本発明の効果を顕著に発揮できる点でより好ましい。木本植物としては例えば、ユーカリ属(Eucalyptus)植物、マツ属(Pinus)植物、サクラ属(Prunus)植物(サクラ(Prunus spp.)、ウメ(Prunus mume)、ユスラウメ(Prunus tomentosa)など)、アボカド属(Avocado)植物、マンゴー属(Mangifera)植物(マンゴー(Mangifera indica)など)、アカシア属(Acacia)植物、ヤマモモ属(Myrica)植物、クヌギ属(Quercus)植物(クヌギなど(Quercus acutissima))、ブドウ(Vitis)属植物、リンゴ(Malus)属植物、バラ属(Rosa)植物、ツバキ属(Camellia)植物、ジャカランダ属(Jacaranda)植物(ジャカランダ(Jacaranda mimosifolia)など)、ワニナシ属(Persea)植物(アボカド(Persea americana)など)が挙げられる。このうち、ユーカリ、マツ、サクラ、マンゴー、アボカド、アカシア、ヤマモモ、クヌギ、ブドウ、リンゴ、バラ、ツバキ、ウメ、ユスラウメ、ジャカランタ等に適用した場合に、より本発明の効果を発揮しうる。中でもユーカリ属植物、マツ属植物、サクラ属植物、マンゴー属植物が好ましく、特に、難発根性として知られるユーカリ、マツ、サクラ、マンゴー、アボカド等に本発明を適用すれば、大きな効果が得られる。
シュートとは、発根能を有する組織全般をいう。該組織としては、枝、茎、頂芽、腋芽、不定芽、葉、子葉、胚軸、不定胚、苗条原基等が例示される。シュートの由来は特に限定されず、温室や屋外に生育している植物個体から得られたものでもよいし、組織培養法により得られた培養組織であってもよいし、天然の植物体の一部の組織であってもよい。また、クローン苗とは、これらの組織が発根して得られる苗をいう。シュートは、挿し穂の母本植物や、多芽体から効率良く取得することができる。中でも、挿し穂(母本植物から得た挿し穂)、母本植物から採取した器官を無菌的に培養することにより得た多芽体、もしくは前記器官を無菌的に育成して得た茎葉であることが好ましい。
本発明においては上述したように、植物のシュートを栽培するにあたり、シュートとして挿し穂を用いてもよい。挿し穂としては、緑枝(当年枝)や熟枝(前年以前に伸びた枝)の他、芽や葉も用いることができる。木本植物の場合では緑枝や熟枝を挿し穂として用い、草本植物の場合では葉や芽を挿し穂として用いるのが普通である。
本発明においては、上記シュートを栽培するにあたり、グルタチオンを用いる。グルタチオンは、その製造条件は特に限定されず、人工的に合成されたものでも、天然物由来のものでもよい。また、精製度も特に問わない。市販品を利用することも可能である。グルタチオンとしては、酸化型と還元型とあり、本発明ではいずれも用い得るが、酸化型グルタチオンが好ましい。本発明においてグルタチオンとして酸化型グルタチオンを用いる場合には、植物体に取り込まれた後、植物体内にて、より安定性に優れる還元型グルタチオンに変化するものと推測される。
本発明において発根用培地とは、植物のシュートから発根させるために用いられる培地を意味する。発根用培地は、銀イオン及び/又は抗酸化剤を含有することが好ましく、銀イオン及び抗酸化剤の両方を含有することがより好ましい。銀イオンは、STSや硝酸銀等の銀化合物(銀イオン源)として培地中に添加すればよい。中でもSTSは、培地に添加してシュートを培養すると、健全な根の発根・伸長が促進されるので、本発明で用いる銀イオン源として好ましい。これは、このSTSに由来する銀イオンが、培地中で、チオ硫酸銀イオンの形態を取り、マイナスに帯電しているためと考えられる。発根用培地中に添加する銀イオンの濃度は、銀イオン源の種類その他の培養条件などにもよるが、銀イオン源の濃度として約0.5μM~約10μMが好ましく、約2μM~約6μMがより好ましい。
本発明において支持体とは、植物のシュートを支持するための支持体である。発根用培地(特に固体培地)を用いる場合などには、支持体は不要の場合があるが、それ以外の場合には通常支持体が利用される。
本発明においては、発根用培地または支持体を納めるための培養容器を用い得る。培養容器としては、従来慣用の培養容器を用いることができ、特に限定されない。例えば、育苗ポット、プラグトレーなどが例示される。培養容器は密閉型でもよいし開放型でもよいが、密閉型のものが好ましい。密閉型の培養容器を用いることにより、散布されたグルタチオンを保持することができる。また、シュートやこれから形成されるクローン苗を取り巻く環境の湿度維持が容易となる。
シュートを栽培する際の栽培条件としては、シュートから発根させ得る条件である限り特に限定されない。栽培条件は、植物の種類やシュートの状態、発根用培地の種類などにより一概に規定することは難しいが、例えば、温度は、約23℃~約28℃であることがより好ましい。光強度は、光合成有効光量子束密度として表され、約10μmol/m2/s~約1000μmol/m2/sであることが好ましく、約50μmol/m2/s~約500μmol/m2/sであることがより好ましい。いずれの場合でも、通常は約2週間~約5週間で、シュートからの発根が観察されるようになる。
