Method for quickly cultivating glyptostrobus seedling through immature embryo

Abstract

The invention discloses a method for quickly cultivating glyptostrobus seedling through immature embryo, and aims at solving the problems that the glyptostrobus sward population is less and the genetic diversity is low due to cutting propagation on the production. The immature strobili of the glyptostrobus cottage plant at the Pingyao Town, Yuhang District, Zhejiang Province is taken as the starting material, the endosperm thereof and the immature embryo are stripped after surface disinfection, the glyptostrobus plant sexual progeny is quickly cultivated through the embryo culture technology,a large number of glyptostrobus seedlings can be acquired within short time. The method disclosed by the invention has the advantages that the glyptostrobus sexual progeny sward is acquired by culturing the immature embryo with endosperm of the glyptostrobus for 30 days, the current status that the glyptostrobus is mainly propagated through the cottage is improved, and the glyptostrobus seedling cultivating speed is accelerated. The method disclosed by the invention is strong in operability, simple and efficient, low in pollution rate, and has significance in protecting the rare or endangeredspecies in the world and quickly cultivating the nursery stock.

Description

technical field [0001] The invention relates to a method for rapidly cultivating Chinese pine seedlings through immature embryos, so as to achieve the purposes of protecting rare and endangered species and rapidly propagating seedlings. Background technique [0002] Water pine, Latin scientific name: Glyptostrobus pensilis; [0003] Alias: water lotus, water emperor pine, metasequoia pine, water pole, long cypress; [0004] Family and genus: Cypress cypress subfamily Cypress; [0005] Origin and distribution: There is only one species of Chinese pine in the genus, which was widely distributed in the northern hemisphere before the Tertiary period. After the Quaternary glaciers, the water pine plants became extinct in Europe and America, and are now only distributed in my country and Vietnam. Water pine grows in latitude 13°09′ (Vietnam)-37°33′ (Shandong Yantai), longitude 102°42′ (Yunming Kunming)-121°31′ (Chinese Taipei), and altitude 32-1980m. Distributed in the Pearl Ri...

AI Technical Summary

Problems solved by technology

Water pine is a tree species that likes moisture. After the seeds mature, they often fall into the swamp. The germination rate is very low or none, and the seedlings grow in water for a long time, and the survival rate is not high.
