Method of relieving high temperature stress of kiwi fruit trees

Abstract

The invention provides a method of relieving the high temperature stress of kiwi fruit trees. The method comprises the following steps of: irrigating kiwi fruit seedlings having five leaves and one heart with melatonin having the concentration of 50-200 micromole/L one time every two days, and irrigating for five times totally. The method has the beneficial effects that the method can protect the completeness of plant cell membranes under high temperature stress, promotes the increase of free proline content in plant bodies, relieves the degradation of kiwi fruit protein under high temperature stress, promotes the increase of soluble sugar content in the plant bodies, enhances and maintains the intracellular osmotic potential ability and can stimulate and induce the activity of SOD, CAT and POD in the plant bodies under high-temperature adverse environmental factors, so that the relatively high active state of the SOD, CAT and POD is maintained, thereby facilitating the removal of H2O2 and maintaining the stability of the cell membranes and improving the high temperature resistance of kiwi fruit.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a method for alleviating high temperature stress of kiwi fruit. Background technique [0002] Temperature is the main limiting factor of the natural geographical distribution of plants, and it is also one of the necessary conditions for plant growth and development. It is also a quantitative factor of plant growth dynamics, because plants must have a certain amount of activity to achieve a certain amount of growth or complete a certain growth period. Accumulated temperature. However, with the deterioration of the global climate environment and the intensification of the greenhouse effect, temperature has become a major stress factor affecting plant growth and development. A large number of studies have found that the normal growth and development of both horticultural plants and field plants will be affected under high temperature stress, which will eventually l...

Problems solved by technology

[0004] At present, there are few methods to alleviate the high temperature stress of kiwifruit, mainly focusing on the use of methyl jasmonate, brassinosteroid and ascorbic acid, such as "The influence of brassinosteroids on the physiological indicators related to heat resistance of kiwifruit seedlings under high temperature stress", "Effects of ascorbic acid on physiological indicators related to heat resistance of kiwifruit seedlings under high temperature stress" and "Effects of methyl jasmonate on membrane lipid peroxidation and related antioxidant enzymes of kiwifruit seedlings under high temperature stress"
