Description
Technical field
The present invention relates to the application on shallow root system vegetable is waterlogging-resistant of a kind of (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate, particularly relate to resist at Solanaceae capsicum plants
Application in flood.
Background technology
Fructus Capsici (Capsicum annum L.) Solanaceae capsicum plants, one of vegetable species that China's cultivated area is maximum, every year
Cultivated area reaches 1,300,000 more than hm2, belongs to shallow root system plant, and root system is thin and delicate, absorbs root less, when soil moisture is too much,
The growth of Fructus Capsici can be affected.The harm of In Middle And Lower Reaches of Changjiang River flood stain frequently occurs, and has had a strong impact on spring and Xia Qiu outdoor cropping Fructus Capsici
Yield and quality, and China plantation Fructus Capsici 60%-70% be outdoor cropping, damage or crop failure caused by waterlogging become domestic open country Fructus Capsici produce master
Want one of stress factors.Fructus Capsici has stronger drought-resistance ability, but resistance to waterlogging ability is more weak, and Fructus Capsici, by after flood, easily occurs macerating root dead
Seedling, yellowing leaf come off and the phenomenon such as fruit drop.Therefore, external measure is taked to improve the resistance to waterlogging ability of Fructus Capsici to promoting Fructus Capsici
Spread and long season cultivation significant.Existing research shows external source Ca2+Can be by regulation pepper seedling root system
The flooding stress injury to plant is alleviated in internal respiration metabolism, but it is only capable of a few days ago spraying one day after with waterflooding just effectively in waterflooding,
And the less effective after spraying.
Although additionally, known (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate can improve the vigor of seed under cryopreservation, improving reply low temperature and the adverse circumstance such as saline and alkaline
Ability, but the application similar with the present invention not yet occurred.
Summary of the invention
It is an object of the invention to provide the new application of a kind of (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate, be applied to (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate alleviate shallow root system vegetables
Dish waterflooding injures, and improves the waterlogging-resistant ability of shallow root system vegetable.
Technical scheme
The invention provides the application of a kind of (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate, be applied to (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate alleviate shallow root system vegetable waterflooding injury.
The most described vegetable is Solanaceae capsicum plants.
Particularly preferred described vegetable is Fructus Capsici.
When described vegetable is Fructus Capsici, it is possible to obtain unexpected alleviation waterflooding injury and improve the good comprehensive of waterlogging-resistant ability
Effect.
The application process of described (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate, the shallow root system vegetable foliage-spray (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate during waterflooding or after waterflooding is molten
Liquid.
No matter the present invention is to spray (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate during waterflooding or after waterflooding, can obtain good alleviation waterflooding injury
Effect.
Such as, the (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate spraying the present invention for after waterflooding 3-8 days also can obtain good effect.
The present invention comprises following preferred technical scheme:
Preferably in scheme, the concentration of described (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution is 0.3-2.0mmol L-1。
The concentration of further preferred described (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution is 0.6-1.0mmol L-1。
Preferably in scheme, spray (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution continuously 1-12 days.
Further preferably spray (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution continuously 3-7 days.
Described (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution is preferably with the aqueous solution obtained that adds water after ethanol solution dissolving.
Described spray during, spray the most continuously to shallow root system vegetable blade face and have lower of liquid.
The volumetric concentration of described ethanol solution is preferably 75-95%.
The blade preferably during waterflooding and after waterflooding turned to be yellow plant diseases leaf and more than 50% area is extractd, and carries out soil
Loose.
Described (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution is preferably preserved by brown reagent bottle before spraying.
Although the present invention has the most only done the waterlogging-resistant experiment of Fructus Capsici, the starting point of research is for improving the waterlogging-resistant gentle of Fructus Capsici
Solution waterflooding injures, it is contemplated that present invention may apply to the vegetables that general vegetable, particularly shallow root system are easily injured by waterflooding
Dish.
Beneficial effects of the present invention
Although prior art having some other application of (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate, but (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate can apply to alleviate plant
Waterflooding injury is that inventor did not expect, the most never has relevant trial in prior art.
(-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate is sprayed the plant leaf surface during waterflooding or after waterflooding by inventor by accident, achieves unexpected good
Good effect.
Present invention reduces the waterflooding injury to shallow root system vegetable, improve the survival rate of shallow root system vegetable, ensured flooding condition
The yield of lower Fructus Capsici, adds peasant income.
In the concrete waterlogging-resistant experimentation of Fructus Capsici, inventor finds, especially by the concentration of (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate solution and
Spray the further optimization of natural law, it is possible to obtain more preferable plant height, root length, whole strain fresh weight, relative conductivity comprehensively improve effect,
It is greatly improved the survival rate of Fructus Capsici.
By substantial amounts of experiment and test, inventor is found surprisingly that in the present invention and improves Fructus Capsici by spraying (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate
Catalase, the activities of antioxidant enzymes such as superoxide dismutase, add osmotic adjustment proline content, reduce by the third two
The accumulation of aldehyde and relative conductivity, improve the activity of anaerobic respiration relevant enzyme ethanol dehydrogenase simultaneously, and make root system keep higher
Malic dehydrogenase, beneficially Fructus Capsici carry out aerobic respiration metabolism.
