Lagerstroemia plant castration-free locellus isolation bagging crossbreeding method

Abstract

The invention relates to a lagerstroemia plant castration-free locellus isolation bagging crossbreeding method, and belongs to the technical field of plant cultivation. The lagerstroemia plant castration-free locellus isolation bagging crossbreeding method comprises the following steps: 1, manufacturing lagerstroemia pistil and stamen locellus isolator; 2, bagging; 3, pollinating, and 4, removing. The lagerstroemia plant castration-free locellus isolation bagging crossbreeding method provided by the invention has the advantages that the 'lagerstroemia pistil and stamen locellus isolator' directly covers flower buds without stripping buds for castrating, so that the operation is simple, and the defect that operation skills are required to be mastered perfect by a castration isolation bagging method; the manual operation of bud stripping and castration is omitted, so that the cost can be reduced, and the defects of manual castration operation and requirement on high cost are overcome; flower organs of each part can be prevented from being damaged, the normal growth and development of flowers can be ensured, and the defect that flower organs can be damaged easily by the castration isolation bagging method can be overcome.

Description

technical field [0001] The invention relates to a hybrid breeding method for plants of the genus Lagerstroemia without male compartment isolation and bagging, and belongs to the technical field of plant cultivation. Background technique [0002] "Hubei Agricultural Sciences", Volume 49, No. 11, November 2010, recorded a research report by Wang Ruiwen, Yang Yanling, etc. on "Research on the Viability Changes of Lagerstroemia in Pollen and Receptivity of Stigma". Around 4:30, the flower buds are loose, the stigma is protruding, and the top is green without mucus; 5:30-6:00, the petals begin to unfold and reveal the anther; At 9:30, a large amount of mucus began to be produced, and the stigma was observed to be covered with pollen; at 16:00 in the afternoon, the calyx closed, and the stigma was still upright outside. On the second day of flowering, the calyx is completely closed, the curved top of the stigma is covered with yellow pollen, the color of the petals becomes lighte...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the hybrid breeding of Lagerstroemia plants adopts the above-mentioned emasculation isolation bagging method, which has the following defects: 1, when carrying out hybrid emasculation, generally adopts the artificial emasculation method, which needs to be mastered to carry out; The operation is time-consuming and labor-intensive, and the production cost is high; 3. The work progress is slow and the efficiency is low; 4. It is difficult to operate the plants with small flowers, and it is easy to peel and damage the ovary
