Method for improving quality of grape fruits by using compound anti-transpiration agent

Abstract

The invention relates to a method for improving the quality of grape fruits by using a compound anti-transpiration agent. In the period of fruit bearing, a hyaluronic acid solution is sprayed; from the initial period of maturation in the beginning to the initial period of maturation, the compound anti-transpiration agent is sprayed onto the surfaces of the fruits, hyaluronic acid can form an edible covered membrane on the surface of the grape skin, and the covered membrane maintains the local environmental humidity of the tissue while hindering the transpiration, thereby increasing the growthspeed of the grape fruits in the first expansion growth period, reducing the weight loss ratio of the fruits, reducing the water evaporation of the fruits, and enhancing the drought resistance ability. In the initial period of maturity of grapes in the beginning, ABA mixing treatment can obviously advance and improve the expression and expression quantity of a VvCWI (cell wall acid invertase) generelated to sugar accumulation and VvUFGT gene related to anthocyanin synthesis in the maturation process, and finally, the content of sugar, anthocyanin and other important quality factors in ripe grape fruits is increased.

Description

technical field [0001] The invention relates to a method for improving grape fruit quality by using a composite anti-transpiration agent, belonging to the technical field of agricultural production. Background technique [0002] my country is the second largest grape producing country in the world. The regions south of the Yangtze River, Guangxi, Fujian, and Taiwan are the main producing areas of grapes. The area of ​​grapes planted by facility agriculture is expanding year by year. As of 2016, the national planting area reached 585,500 hm 2 However, due to the different growth characteristics of the grape itself and the surrounding environment, the reducing sugar, total acid, ear shape, fruit surface color, etc. of the grapes are all different. Therefore, limited by the quality of grapes, my country's grape exports still do not have a competitive advantage in the international market, and have been in a trade deficit for a long time. [0003] There are many reports at home...

Problems solved by technology

But at the same time, a series of problems have been exposed: such as excessive toxicity, pollution to the environment (such as: mercuric benzene acetate), high cost (abscisic acid ABA), poor water solubility, low adhesion (such as: fulvic acid) affecting light Contracting effect (film type), etc. At the same time, the current anti-transpiration agent is mainly water retention, mainly focusing on the research and development of new varieties and the dosage of existing varieties in increasing crop yield and / or fruit post-harvest storage under drought-resistant conditions. It has no effect on the reducing sugar, total acid and color of the fruit, and cannot improve the quality of the fruit

[0006] After searching, there is no public report on the use of hyaluronic acid as a plant anti-transpiration agent, and there is no report on using it as a plant anti-transpiration agent and improving fruit quality
