Hybrid seedling culture method capable of increasing cherry cold resistance

Abstract

The invention belongs to the technical field of fruit culture and particularly relates to a hybrid seedling culture method capable of increasing cherry cold resistance. The method specifically includes the steps of firstly, culturing stocks; secondly, culturing scions; thirdly, grafting, and culturing after grafting. Hybrid seedlings obtained by the method have the advantages that membrane destroying and leakage under low temperature can be inhibited effectively, calcium ions are inhibited from entering cells, phospholipid degradation is lowered, cell membrane stability is protected, the balance between the generation and the elimination of free radicals in cherry trees is kept favorably, membrane lipid peroxidation can be avoided, relative intracellular environment stability is kept effectively, plasma membrane freezing injury degree is lowered, more moisture is retained, the probability of protoplasm injury and death caused by freezing is reduced, and cells and tissue are protected.

Description

technical field [0001] The invention belongs to the technical field of fruit seedling cultivation, in particular to a hybrid seedling cultivation method for improving cold resistance of cherries. Background technique [0002] Cherry, the fruit is gorgeous, high-quality, nutritious, known as the "treasure in the fruit", the fruit matures the earliest among the deciduous fruit trees in the north, and enjoys the reputation of "the first spring fruit". Its dormancy period is relatively short, and its cold resistance is weak. Low temperature is an important factor that limits the distribution and growth of plants. Especially in inland areas, the winter is long and cold, which makes cherries suffer from low temperature damage, often resulting in damage to flower buds and branches. When severe, the whole plant will die and cannot survive the winter safely; therefore, inventing a kind of high cold resistance cherry can effectively promote the rapid development and promotion of the c...
