Method for inducing flower bud differentiation and fruiting of blueberry

Abstract

The invention discloses a method for inducing flower bud differentiation and fruiting of blueberries. The method comprises steps of tree vigor recovery, short-day treatment, gradient cooling, vernalization and gradient heating. By controlling lighting conditions, and adjusting culture temperature control, moisture and culture time, flower bud differentiation, blossoming and fruiting of blueberry plants after fruit harvesting are induced, practical problems that blueberries are easily limited by seasons, blossom once and harvest once every year, and the like, can be broken through, on premise that fruit quality is ensured, blueberries are mature twice per year, even whole year production can be achieved. Therefore, not only are great economical benefits made, but also great practical significances can be brought to development of the blueberry industry.

Description

Technical field [0001] The invention belongs to the technical field of blueberry tissue culture, and specifically relates to a method for inducing blueberry flower bud differentiation and fruiting. Background technique [0002] Blueberry (Vaccinium ssp.L.) is a plant of the genus Vaccinium ssp. of the Ericaceae family (Ericaceae), and is one of the economical berry species with high nutritional value. [0003] Blueberry fruits are rich in antioxidants such as anthocyanins and vitamins. They have good health care value and are very popular among consumers. In recent years, consumers have increasingly demanded blueberry fruits. [0004] The flowering period of blueberries is concentrated, and the fruit supply period and shelf life are relatively short. At the same time, due to the seasonal cycle, most blueberry varieties can only bloom once a year and harvest the fruit once a year, resulting in the seasonality of the shelf life of blueberries. Strong, there is often a phenomenon that ...

AI Technical Summary

Problems solved by technology

[0004] The blueberry flowering period is concentrated, the fruit supply period and shelf life are short. At the same time, due to seasonal periodicity, most blueberry varieties can only bloom once a year and harvest fruit once a year in production practice, resulting in a relatively short shelf life of blueberries. Strong, the phenomenon that the supply of blueberry fruit is often in short supply

[0005] Temperature, humidity and light are the three factors that affect the differentiation of blueberry flower buds. However, the relationship between light conditions and blueberry flower bud differentiation, especially how to induce blueberry flower bud differentiation by controlling light and temperature conditions, so as to achieve two crops a year, etc. Research not yet reported
