Abstract
The present invention's provides a kind of application of methyl jasmonate, and the waterflooding that methyl jasmonate is applied to alleviate shallow root system vegetables injures, and improves its waterlogging-resistant ability.Injury present invention reduces waterflooding to shallow root system vegetables improves its survival rate, has ensured the yield of shallow root system vegetables under flooding condition, has increased peasant income.
Description
Technical field
The present invention relates to a kind of application of methyl jasmonate on shallow root system vegetables are waterlogging-resistant, more particularly in Solanaceae capsicum
Application on platymiscium is waterlogging-resistant.
Background technology
Capsicum (Capsicum annum L.) Solanaceae capsicum plants, one of maximum vegetable species of China's cultivated area,
Per annual planting area up to 1,300,000 hm2 or more, belong to shallow root system plant, root system is thin and delicate, and absorption root is less, when soil moisture is excessive
When, the growth of capsicum can be influenced.The harm of In Middle And Lower Reaches of Changjiang River flood stain frequently occurs, and has seriously affected spring and summer and autumn open country is planted
The yield and quality of capsicum is trained, and the capsicum 60%-70% of China's plantation is outdoor cropping, damage or crop failure caused by waterlogging has become domestic open country capsicum
One of major stress factors of production.Capsicum has stronger drought-resistance ability, but resistance to waterlogging ability is weaker, and capsicum is after by flood, easily
Phenomena such as root dead seedling is macerated in appearance, yellowing leaf falls off and fruit drop.Therefore, external measure is taken to improve the energy of resistance to waterlogging of capsicum
Power to promote capsicum be widely applied and long season cultivation it is significant.It is existing research shows that external source Ca2+It can pass through
Pepper seedling root system internal respiration metabolism is adjusted to alleviate injury of the flooding stress to plant, but it is only capable of a few days ago and flooding in waterflooding
Water sprays just effectively one day after, and the less effective after spraying.
In addition, although known methyl jasmonate can improve the vigor of seed under cryopreservation, reply low temperature and salt are improved
The ability of the adverse circumstances such as alkali, but not yet there is the application similar with the present invention.
Invention content
The purpose of the present invention is to provide a kind of new applications of methyl jasmonate, methyl jasmonate are applied to alleviate shallow
Root system vegetables waterflooding injures, and improves the waterlogging-resistant ability of shallow root system vegetables.
Technical scheme of the present invention
The present invention provides a kind of application of methyl jasmonate, methyl jasmonate is applied to alleviate shallow root system vegetables waterflooding
Injury.
It is preferred that the vegetables are Solanaceae capsicum plants.
The particularly preferred vegetables are capsicum.
When the vegetables are capsicum, unexpected alleviation waterflooding injury can be obtained and improve the good of waterlogging-resistant ability
Good resultant effect.
The application process of the methyl jasmonate, the shallow root system vegetables foliage-spray jasmonic during waterflooding or after waterflooding
Methyl ester solution.
The present invention sprays methyl jasmonate either during waterflooding or after waterflooding, can obtain good alleviation waterflooding
The effect of injury.
For example, good effect can also be obtained by spraying within 3-8 days after waterflooding the methyl jasmonate of the present invention.
The present invention includes following preferred technical solution：
In preferred scheme, a concentration of 0.3-2.0mmol L of the methyl jasmonate solution-1。
A concentration of 0.6-1.0mmol L of the further preferred methyl jasmonate solution-1。
In preferred scheme, methyl jasmonate solution is continuously sprayed 1-12 days.
Further preferably continuously spray methyl jasmonate solution 3-7 days.
The methyl jasmonate solution is preferably the aqueous solution that after being dissolved using ethanol solution plus water obtains.
It is described spray during, preferably continuously spray to shallow root system vegetables blade face to have and be dripped under liquid.
The volumetric concentration of the ethanol solution is preferably 75-95%.
It is preferred that being extractd during waterflooding and to the blade of plant diseases leaf and 50% or more area jaundice after waterflooding, go forward side by side
Row loosing soil.
The methyl jasmonate solution is preferably preserved by brown reagent bottle before spraying.
Although the present invention has only done the waterlogging-resistant experiment of capsicum in embodiment, the starting point of research is to improve the anti-of capsicum
Flood and alleviation waterflooding injury, it is contemplated that present invention may apply to general vegetables, especially shallow root system is easy by waterflooding
The vegetables of injury.
Beneficial effects of the present invention
Although there is some other applications of methyl jasmonate in the prior art, methyl jasmonate can be applied to delay
It is that inventor did not expected to solve plant waterflooding injury, also never there is relevant trial in the prior art.
Plant leaf surface during methyl jasmonate is sprayed on waterflooding by inventor by accident or after waterflooding achieves expectation
Outer good result.
Injury present invention reduces waterflooding to shallow root system vegetables improves the survival rate of shallow root system vegetables, has ensured and flooded
The yield of capsicum, increases peasant income under water condition.
In the waterlogging-resistant experimentation of specific capsicum, inventor has found, especially by the dense of methyl jasmonate solution
Advanced optimizing for number of days is spent and sprayed, better plant height, root long, whole strain fresh weight, relative conductivity synthesis can be obtained and changed
Kind effect, greatly improves the survival rate of capsicum.
Through a large number of experiments and test, inventor are found surprisingly that in the present invention by spraying methyl jasmonate raising
The activities of antioxidant enzymes such as the catalase of capsicum, superoxide dismutase, increase osmotic adjustment proline content,
Accumulation and the relative conductivity of malonaldehyde are reduced, while improving the activity of anaerobic respiration relevant enzyme alcohol dehydrogenase, and makes root
System keeps higher malic dehydrogenase, is conducive to capsicum and carries out aerobic respiration metabolism.
