Description

Lagerstroemia plant castration-free separated bagging crossbreeding method

Technical Field

The invention belongs to the technical field of plant cultivation, and particularly relates to a lagerstroemia plant castration-free compartmental isolation bagging crossbreeding method.

Background

The Hubei agricultural science, 11 th volume 49 of 2010, 11 th month, records the research reports of Wang Rui Wen, Yanyanling and the like about the research on the viability change of the lagerstroemia indica pollen and the stigmatability, and the research reports are as follows: the crape myrtle has loose buds at 4:30 in the morning, the stigma stretches out, and the top end is green and has no mucus; the petals are unfolded at 5:30-6:00 to expose anthers; the petals are 7:00-7:30, and a small amount of transparent mucus appears when the stigmas are completely unfolded; a large amount of mucus is generated at the beginning of 8:00-9:30, and pollen is fully distributed on the stigma can be observed; the calyx is closed at 16:00 pm, and the stigma is still upright outside. The calyx of the second smallpox blossoms is completely gathered, the bent top of the stigma is full of yellow pollen, the color of the petals is lightened, the ovary is enlarged, the flowers bloom for 3-5 days, and the petals are completely withered. Therefore, the granting performance of the crape myrtle stigma is strongest on the day after the flowers bloom, the granting performance is obviously reduced on the second day, and the granting performance is completely lost on the third day.

The basic method is to perform emasculation and bagging before one variety of a certain plant blooms and pollinates, and select pollen of the other variety for artificial pollination to realize the breeding of new varieties. The crossbreeding method is also suitable for breeding new varieties of lagerstroemia plants.

The emasculation isolating bagging method for amphoteric flower plant hybridization is characterized by that before the amphoteric flower plant hybridization the immature anther in the flower bud can be removed so as to prevent self-pollination, and after the emasculation the flower bud can be immediately bagged (generally using paper bag to make bagging) and isolated.

In the prior art, the castration isolation bagging method is adopted for crossbreeding of lagerstroemia plants, and has the following defects: 1. when the hybridization castration is carried out, a manual castration method is generally adopted and can be carried out only by skilled mastering; 2. The manual operation is time-consuming and labor-consuming, and the production cost is low.
