Technical Field

The invention belongs to the technical field of forest flower promoting and flower controlling, and particularly relates to a method for promoting the differentiation of male and female flowers of cryptomeria fortunei.

Background

The cryptomeria fortunei is a big tree of cryptomeria genus of the family of the cedaceae, has fast growth, strong adaptability and excellent material quality, and is an important timber tree species in south China. In the production practice of the cryptomeria fortunei seed orchard, the number of female globeflower or male globeflower is generally controlled according to different production requirements, the flower synchronization is coordinated, and for example, in order to improve the seed yield, more female flowers need to be bloomed from a certain excellent provenance or family (clone); in order to improve pollination effectiveness and ensure seed quality, the quantity of the male ball flowers needs to be regulated, the flowers are the most important reproductive organs of plants, and multiple ways such as autonomous regulation, vernalization, photoperiod, exogenous hormone regulation and the like exist for flower induction, differentiation and development. Among them, exogenous hormone treatment is simple and rapid, but the treatment effect is greatly different according to different plant species, some plants are sensitive to exogenous hormone in flower bud differentiation and development, and some are completely ineffective. Exogenous hormones such as Gibberellin (GA), abscisic acid (ABA) and florigen (BHL) can promote early flowering and fructification of cryptomeria fortunei, but no effective method exists at present for artificially controlling the differentiation and flowering number of female and male globeforms of cryptomeria fortunei.
