Abstract
The invention discloses a plant cold resistant agent. The cold resistant agent comprises the following components: 1.0 to 3.0mmol/L of salicylic acid, and 45 to 60mumol/L of methyl iasmonate. A method for cold resistance of the plants by using the plant cold resistant agent comprises the following step of: spraying the plant cold resistant agent on the leaves of the plants in 12 to 72 hours before cold wave comes, so that the plant cold resistant agent naturally flows down from the leaves. The plant cold resistant agent and the method for cold resistance of the plants greatly improve the cold resistance of the plants, and reduce the loss of low-temperature harm.
Description
Technical field
The present invention relates to agricultural technology field, particularly keep out the cold agent and be used for the method for plant cold resistance of a plant species.
Background technology
At arctic weather, plant can be damaged to plants caused by sudden drop in temperature and these two kinds of low temperature harm of freeze injury usually.When low temperature environment acts on plant, can cause the variation on a series of physiology, biochemistry and the molecular biology in the plant corpus, mainly comprise the change of biofilm structure and composition, the increase of many specific proteinses, sugar, osmotic adjustment material (betain and proline etc.), and the appearance of some new enzymes etc.Plant corpus performance is made a living long and metabolism is suppressed, in the time of seriously even cause and irreversible injury finally cause plant death.Therefore, if the harm of the low temperature of plant occurrence of large-area will bring great economic loss.Though some plant can not be dealt with problems concerning most of plants by adding such as brooder and careless waiting facility of going to a winter resort.Therefore, deterioration day by day along with global ecotope, research to plant cold resistance is extremely urgent, develops method that a plant species keeps out the cold agent and be used for plant cold resistance with the cold-resistant anti-cold energy power that improves plant and to reduce the loss that low temperature harm causes be that ten minutes is necessary.
Summary of the invention
The object of the present invention is to provide keep out the cold agent and be used for the method for plant cold resistance of a plant species, improve the cold-resistant anti-cold energy power of plant.
The invention provides the plant species agent that keeps out the cold, its composition comprises salicylic acid and methyl jasmonate, and component is as follows: salicylic acid 1.0～3.0mmol/L, methyl jasmonate 45～60 μ mol/L.
The present invention also provides the plant species agent that keeps out the cold to be used for the method for plant cold resistance, wherein, arrives preceding 12～72 hours at cold wave, sprays the blade of described plant with the agent that keeps out the cold of described plant, and the agent that keeps out the cold of described plant is flowed down from described leaf natural.
Preferably, carry out root and irritate, make the following ground moistening of tree crown scope of described plant with the agent that keeps out the cold of described plant.
Keep out the cold agent and be used for the method for plant cold resistance of plant provided by the invention has following advantage:
1, cost of material is low, wide material sources;
2, process equipment is simple, processing ease, and processing cost is low;
3, transportation and storage are convenient, use simply, and environmental sound.
Embodiment
For purpose of the present invention, feature are become apparent, below the specific embodiment of the present invention is further described.
In an embodiment of the present invention, all use cucumber seedling as test material.The anti-cold finger of cucumber seedling is designated as: malonaldehyde (MDA) content, peroxidase (POD) content, catalase (CAT) content, superoxide dismutase (SOD) content.Wherein, malonaldehyde is one of product of plant inner cell peroxidation of membrane lipids, and its generation can aggravate the damage of cell membrane.Therefore, the degree that the height of mda content and cell membrane the are hurt relation that is proportionate has substantially also reflected the anti-cold energy power of plant.Simultaneously, the activity of protective enzymes such as peroxidase, catalase and superoxide dismutase is high more, and the cold resistance of plant is strong more.This is because under normal circumstances, exist oxygen production and these two processes of removing in the plant cell.The low temperature environment stress can promote oxygen production, and the excessive accumulation of active oxygen in plant corpus can damage the film system.Exist the removing protective enzyme system of active oxygen and free radical in the plant corpus, comprise peroxidase, catalase and superoxide dismutase etc., they can eliminate this murder by poisoning, keep cell membrane stability.Certainly, application of the present invention is not subject to cucumber seedling, can also be applied to plants such as other vegetables, woods fruit, flowers.
Embodiment 1
The plant agent component that keeps out the cold: salicylic acid 1.0mmol/L, methyl jasmonate 60 μ mol/L.
Arrived preceding 12 hours at cold wave, spray the blade of cucumber seedling, the plant agent that keeps out the cold is flowed down from leaf natural, carry out root simultaneously and irritate, make the following ground moistening of tree crown scope with the plant agent that keeps out the cold.Then, cucumber seedling was handled 40 hours under the low temperature environment of 6 ℃ of temperature, relative moisture 70%～75%, at last the anti-cold finger mark of cucumber seedling was tested.Test shows was compared with not using the keep out the cold situation of agent of plant, and the MDA content of the cucumber seedling of handling has reduced by 12.2%, and the POD activity exceeds 19.5%, and the CAT activity hangs down 17.1%, and the SOD activity is former 1.2 times.This shows that the cold resistance of cucumber seedling obtains bigger improvement, has reduced the loss of low temperature harm.
Embodiment 2
The plant agent component that keeps out the cold: salicylic acid 2.0mmol/L, methyl jasmonate 50 μ mol/L.
Arrived preceding 24 hours at cold wave, spray the blade of cucumber seedling, the plant agent that keeps out the cold is flowed down from leaf natural, carry out root simultaneously and irritate, make the following ground moistening of tree crown scope with the plant agent that keeps out the cold.Then, cucumber seedling was handled 40 hours under the low temperature environment of 6 ℃ of temperature, relative moisture 70%～75%, at last the anti-cold finger mark of cucumber seedling was tested.Test shows was compared with not using the keep out the cold situation of agent of plant, and the MDA content of the cucumber seedling of handling has reduced by 12.9%, and the POD activity exceeds 20.1%, and the CAT activity hangs down 17.9%, and the SOD activity is former 1.3 times.This shows that the cold resistance of cucumber seedling obtains bigger improvement, has reduced the loss of low temperature harm.
Embodiment 3
The plant agent component that keeps out the cold: salicylic acid 3.0mmol/L, methyl jasmonate 45 μ mol/L.
Arrived preceding 72 hours at cold wave, spray the blade of cucumber seedling, the plant agent that keeps out the cold is flowed down from leaf natural, carry out root simultaneously and irritate, make the following ground moistening of tree crown scope with the plant agent that keeps out the cold.Then, cucumber seedling was handled 40 hours under the low temperature environment of 6 ℃ of temperature, relative moisture 70%～75%, at last the anti-cold finger mark of cucumber seedling was tested.Test shows was compared with not using the keep out the cold situation of agent of plant, and the MDA content of the cucumber seedling of handling has reduced by 13.4%, and the POD activity exceeds 20.6%, and the CAT activity hangs down 18.2%, and the SOD activity is former 1.4 times.This shows that the cold resistance of cucumber seedling obtains bigger improvement, has reduced the loss of low temperature harm.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
