Drug for improving initiation rate of flower buds of Fuji apples and measuring method

Abstract

The invention belongs to the technical field of cultivation of garden vegetables, and discloses a drug for improving the initiation rate of flower buds of Fuji apples and a measuring method. The drugfor improving the initiation rate of the flower buds of the Fuji apples is glucose. Exogenous glucose is sprayed to process the variety of Changfu 2 of the Fuji apples, the influence of the exogenousglucose on flower-bud initiation is studied, and based on an RNA-seq sequencing means, glycometabolism and florescence related gene expression modes in the process that the exogenous glucose regulatesthe apple flower-bud initiation are comprehensively analyzed; a resequencing technology is adopted to identify and compare variation difference of DNA polymorphism of florescence related genes of budmutation varieties with different florescence characteristics and discover differential genes. Through glucose processing, the increment of the contents of soluble sugar and starch in short shoots and terminal buds is promoted, growth of the short shoots and the terminal buds in the physiological differentiation phase of the flower buds is facilitated, and the florescence rate of the Fuji applesis obviously increased.

Description

technical field [0001] The invention belongs to the technical field of gardening and vegetable cultivation, and in particular relates to a medicament and a measuring method for improving the flower bud germination rate of Fuji apples. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows:According to FAO (2016) statistics, the global apple cultivation area reached 5,293,300 hectares, with a total output of 89,329,200 tons and a unit yield of 168,758 hectares per hectare. Apple has been a cultivated crop for a long time, and its varieties have gradually increased during the long development process. It is one of the most important agricultural economic crops in the world. At the same time, apples are the largest commercial fruit variety in my country. FAO (2016) statistics show that my country's apple cultivation area is 2.3839 million hectares, with an output of 44.4486 million tons. Since 1993, my country's apple ...

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: Fuji apple is the largest variety with the highest yield as my country's cultivated area, and there is difficulty in flowering and low fruit yield in the production process.

[0004] The difficulty and significance of solving the above technical problems: 'Fuji' is the main cultivated variety in my country's apple industry, accounting for more than 70% of the total apple planting area in the country, but there is a common problem of difficulty in flowering in production, which limits the development of the apple industry in northern China. develop

In actual production management, measures such as bud carving, girdling, and ring cutting are often used to alleviate the above problems to a certain extent, but it will have an irreversible impact on the tree itself and the implementation process is labor-intensive and time-consuming.

Therefore, the molecular mechanism of Fuji apple flower induction and the discovery of simple Fuji flower promotion techniques have certain practical guiding significance for solving the problems of low flower formation rate, poor flower quality and unstable yield of Fuji varieties in production.

In recent years, research on the relationship between sugars and plant flowering has become more and more extensive, but the underlying molecular mechanism in apples is still not very clear
