Abstract
The invention relates to a method for improving fruiting performance of tetraena mongolica maxim. The method is characterized by comprising the following steps of: when the tetraena mongolica maxim revives every year, removing dust on tetraena mongolica maxim plants, and spraying 100 ml of aqueous solution of 2-6mg/L cytokinin or 100 ml of aqueous solution of 200-400mg/L gibberellin and 2-6mg/L cytokinin per square meter of tetraena mongolica maxim plants in wind-free and sunny weather. The method has the benefits that the fruiting performance of the tetraena mongolica maxim can be improved by spraying exogenous hormones, thousand seed weight and vitality of seeds of the tetraena mongolica maxim are improved, the abortion rate of the seeds of the tetraena mongolica maxim is reduced, and the method is easy to operate and provides a new path for improving the current development and propagation situations of the tetraena mongolica maxim. According to the method, the growth and propagation performance of the tetraena mongolica maxim is controlled by using different plant growth hormones for the first time, and a new path is provided for improving the fruiting performance of the tetraena mongolica maxim and changing the endangered status of the tetraena mongolica maxim.
Description
Technical field
The present invention relates to the method that wooden seed production ability is closed in a kind of raising four.
Background technology
Four close wood (Tetraena mong olica Maxim) is zygophyllaceae (Zygophyllaceae) machaka, is 1.4 hundred million years preceding Tethys deleted species, be described as " giant panda " in the plant, and be the first-grade state protection plant.Its distribution is very narrow, worldwide sporadicly sporadically appears in Russia, Ukraine some areas, and concentrate four of growth in flakes to close wood and exist only in China's Wuhai and spur mountain area northernmost around the Chinese ephedra ditch, be that this distinguishes endemic species.In its area; Four close the constructive species that wood often becomes the eremium; Its existence not only has important significance for theories to understanding Tethys flora and vegetation origin, and also plays an important role to keeping NORTHWEST CHINA portion area bio-diversity and ecosystem integrality.And medicinal test shows mainly contains rich in amino acid, alkaloid, flavonoids, sterols, organic acid and phenolic compound in its leaf, and bioavilability is high, has broad application prospects.Four close wood classification position very isolated; Relevant to four close wood research before the protection zone is set up, just carry out, but people are deep not enough to its understanding, and itself is again the Main Constructive Species of this area vegetation; If research and protection work lag behind; Not only its allied species is difficult to seek, and causes dying out of these rare or endangered species, but also can cause the irreversibility of ecotope to destroy.
Finding four through investigation in many ways, to close wood endangered, and it is very urgent with Study on breeding that it is implemented protection.At present the researcher for four close wooden raising technology research mainly concentrate on cultured in vitro and aspects such as organ generation and wild degradation mechanism; And it is not deep enough to close the research of wooden seed production ability to four; To bloom, the restriction of aspect such as the research of fertilization, achievement is thorough inadequately, the raising technology under the natural conditions is failed the progress of making a breakthrough property.Wherein its thousand grain weigth is low, and the low and seeds abortion rate height of seed vitality is one of bottleneck that limits its self-reproduction, breeds the research of performance and does not appear in the newspapers as yet and close wood with regard to plant hormone to four.
Summary of the invention
The purpose of this invention is to provide the method that wooden seed production ability is closed in a kind of raising four; Can utilize different plant hormones handle four close wooden plant with improve four close wooden seed seed production abilities such as thousand kernel weight, seed vitality, solve present four and close wood breeding difficulty and endangered present situation.
The method that wooden seed production ability is closed in a kind of raising four; Its special feature is; When comprising the steps: that closing wood every year four turns green, the dust that removal four is closed on the wooden plant is selected calm bright day gas; Close the aqueous solution that consumption that wooden plant sprays 100ml according to every square meter sprays the 2-6mg/L basic element of cell division to four, or 200-400mg/L gibberellin adds the aqueous solution of the 2-6mg/L basic element of cell division.
If wherein, will once spray again spraying rainfall in back three days.
The beneficial effect of the inventive method is; Can utilize to spray the seed production ability that wood plant is closed in exogenous hormone improvement four, improve the thousand kernel weight and the seed vitality of its seed, reduce the abortion rate of its seed; And method of operating is simple, closes to improving four that wood is grown and the breeding present situation provides new approach.The present invention utilizes different auxins to regulate and control four first and closes the growth of wood and breed performance; Through under the observation different disposal four close wood indexs such as thousand kernel weight, seed vitality; In the hope of to improve four close wooden seed production ability best plant hormone proportioning, four close wooden seed production ability for improving, improve four and close wooden situation in imminent danger new approach is provided.
Embodiment
The technical scheme that the present invention adopted is to close wood annual four to select calm bright day gas in turning green, and sprays several kinds of hormones, and spraying behind the hormone can not have precipitation in three days, otherwise needs sprinkling again, measures each seed production ability index of correlation afterwards.
Embodiment 1:
Close in wood turns green four, remove four dusts that close on the wooden plant, select calm bright day gas, close wooden plant to four and spray the aqueous solution of the 4mg/L basic element of cell division (CTK), after spraying hormone, do not have rainfall in three days according to consumption (every square meter sprays 100ml).
Record four closes indexs such as wood (seed) thousand kernel weight and seed vitality when four close wooden seed maturity.The thousand kernel weight of wherein not spraying hormone is 1.0581g, and four after utilizing the 4mg/L basic element of cell division to handle closed wooden thousand kernel weight and be 1.6232g, and comparison has improved 53.4% according to strain, and its seed vitality is 6.7mg.g
-1.h
-1, contrast is merely 2.8mg.g
-1.h
-1, be significantly higher than contrast, therefore effectively improved four close wooden seed thousand kernel weight and seed vitality.
Embodiment 2:
Four close in wood turns green; The dust that removal four is closed on the wooden plant is selected calm bright day gas, closes wooden plant according to consumption (every square meter sprays 100ml) to four; Spray the aqueous solution of 250mg/L gibberellin (GA)+4mg/L basic element of cell division (CTK), after spraying hormone, do not have rainfall in three days.
Record four closes indexs such as wooden thousand kernel weight and seed vitality when four close wooden seed maturity.The thousand kernel weight of not spraying hormone is 1.0581g, and four after utilizing the aqueous solution of 250mg/L gibberellin (GA)+4mg/L basic element of cell division (CTK) to handle to close wooden thousand kernel weight be 1.3123g, comparison improves 24.0% according to strain, its seed vitality is 7.1mg.g
-1.h
-1, contrast is merely 2.8mg.g
-1.h
-1, effectively improved four close wooden seed seed production ability.
Claims (2)
- One kind improve four close wooden seed production ability method; It is characterized in that; When comprising the steps: that closing wood every year four turns green, the dust that removal four is closed on the wooden plant is selected calm bright day gas; Close the aqueous solution that consumption that wooden plant sprays 100ml according to every square meter sprays the 2-6mg/L basic element of cell division to four, or 200-400mg/L gibberellin adds the aqueous solution of the 2-6mg/L basic element of cell division.
- 2. the method that wooden seed production ability is closed in a kind of raising four as claimed in claim 1 is characterized in that: if wherein spraying rainfall in back three days, then once spray again.
