Method for culturing and propagating descendants of platycrater arguta through immature seeds

Abstract

The invention discloses a method for culturing and propagating descendants of platycrater arguta through immature seeds, which aims at solving the problem of underdeveloped seed propagation of rare platycrater arguta of national secondary protection. The method is that the immature fruits of platycrater arguta are collected under the natural condition; the surfaces of the fruits are sterilized, then the immature seeds and some ovary tissue are picked off to propagate the descendants of platycrater arguta by the culture technology, so as to obtain more sterile seedlings of platycrater arguta. The method has the advantages that the explants are the immature seeds which are cultured through an artificial medium, and therefore, the defect of undeveloped propagating of the seeds can be reduced, and more platycrater arguta plants can be obtained within a short period. According to the method, the operability is high, simple and practical effects are achieved, the pollution rate is low, and the method has important significance on storage and quick propagation of rare plants.

Description

technical field [0001] The invention relates to a method for cultivating and breeding offspring of calyx arachnids by cultivating immature seeds, and relates to the technical field of achieving the purpose of preserving and propagating rare species by improving the breeding level of seeds. Background technique [0002] Arachnecalyx is a species of the genus Arachnea ( Platycrater ) plants are small deciduous shrubs that grow under evergreen forests in low mountains and hills at an altitude of 400-1000 meters. They like to grow beside streams and damp bare rocks. They grow poorly under strong light and are 0.5-1 meters high. The flowering period is July, and the fruit matures in October, with many seeds and dark brown. It is a single species endemic to East Asia, distributed intermittently in China and Japan, and distributed in Zhejiang, Anhui, Jiangxi, Fujian and other places in China. In addition to being used as an ornamental, it also has important scientific value for t...

AI Technical Summary

Problems solved by technology

It was found that in the two methods, the mature seeds could not germinate normally, indicating that it is very difficult for the calyx to use seeds to reproduce

Therefore, there is an urgent need for a complete set of technologies and rapid propagation systems that can improve the seed reproduction of the calyx to rescue and multiply this endangered plant, but so far there is no research report on this aspect
