A kind of desert rose pollination crochet and desert rose artificial hybridization method

Abstract

The desert rose pollination hook provided by the invention comprises a handle and a needle bar, and the needle bar is composed of a straight bar section and a bent section. The steps of artificial hybridization of desert roses using desert rose pollination crochet are as follows: (1) select the male parent flower; Do not grow on the same desert rose; (3) extend the bent section of the pollination hook of the desert rose into the pollen sac of the male parent flower, so that the pollen adheres to the bent section; The bent section of the pollen of the flower extends into the anther sac of the female parent flower, and then the bent section is pulled out from the anther sac, so that the pollen of the male parent flower falls onto the stigma of the female parent flower. Using the method provided by the invention to artificially pollinate the desert rose will not destroy the structure of the male parent flower and the female parent flower, will not lead to the early termination of the life cycle of the female parent flower due to damage, and improve the pollination efficiency and success rate.

Description

technical field [0001] The invention relates to the technical field of plant artificial pollination, in particular to an artificial hybridization method for desert roses. Background technique [0002] Desert rose, also known as Tianbao flower, belongs to Apocynaceae, is a succulent plant, that is, a succulent plant, and the flowers that bloom are generally single-petal flowers. like figure 1 As shown, the flower of desert rose is shaped like a small trumpet, and the stamens and pistils are wrapped in a trumpet-shaped flower tube 1. The stamens include an anther 2 at the bottom of the flower tube and an extension 3 extending upward from the top of the anther 2, and the pollen Located in the pollen sac 2, the flower of the desert rose generally has five stamens, and the tops of the anther sacs 2 of the five stamens gather together to form a cone-shaped space, and the stigma 4 of the pistil is located in the cone-shaped space, so the stamens Both the anther 2 and the stigma 4...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to solve the problem that desert roses are self-fertile and not easy to grow fruit pods, and provide a desert rose pollination crochet and desert rose artificial hybridization method, which will not damage the parent during artificial pollination. The structure of the parent flower and the female parent flower will not cause the female parent flower to end its life cycle prematurely due to damage, improving pollination efficiency and success rate
