Method for inducing differentiation of flower buds of bayberry female tree to form staminate flowers

Abstract

The invention discloses a method for inducing differentiation of flower buds of a bayberry female tree to form staminate flowers. According to the method, in a flower bud differentiation period of a bayberry female tree, a plant growth inhibitor is applied to branches, differentiation of the flower buds of bayberry is induced to form staminate inflorescence, wherein the plant growth inhibitor comprises one or more of paclobutrazol, uniconazole, prohexadione calcium and triiodobenzoic acid. The method is simple, convenient, fast and efficient, and can provide bayberry hybridization with male parent pollen which has clear source and property, so that bayberry crossbreeding is smoothly carried out. The method provides a base for culturing diversified bayberry varieties.

Description

technical field [0001] The invention belongs to an important part of bayberry hybrid breeding, and relates to a key technology and a specific operation method for providing a large amount of bayberry pollen with clear sources and clear fruit phenotypes for bayberry hybrid breeding, and specifically relates to a method for inducing flower buds of female bayberry trees to differentiate into male flowers. Background technique [0002] Bayberry ( Myrica rubra (Lour.) Sieb. et Zucc. ) is a perennial fruit tree of Myricaceae and Myrica rubra, an evergreen tree, and is an economic fruit with Chinese characteristics. One of people's favorite fruits in summer, and it has the effects of promoting body fluid and quenching thirst, helping digestion, relieving alcohol and summer heat. Waxberry fruit is rich in nutrients. In addition to being rich in a variety of essential nutrients such as vitamins, sugars, calcium, phosphorus, sodium, iron, zinc and other minerals, it also contains a l...

Problems solved by technology

[0006] To carry out cross-breeding, it is necessary to clarify the fruit traits of the parents, so that the male and female parents can be selected for cross-breeding. Since bayberry is dioecious, we can only clarify the fruit traits of the female parent, but cannot identify the male parent. Therefore, it is impossible to select parents with complementary traits for cross-breeding according to people's wishes. Therefore, all cultivars of bayberry are cultivated through bud mutation or fitness variation.
