Features of propagation by seeds of rare and endangered plant species in culture

Abstract

The article is devoted to the conservation of rare and endangered species in a culture The problems and features of reproduction by seeds of these species were been considered. The stages were been distinguished – preparatory (informational), seed collection, drying, peeling, storage, germination, genetic identification. Approaches to seed collection and storage were been presented. It is proposed to use a refrigeration chamber (+ 4 ° C) for long-term storage of seeds.

Ssr Analysis on the Genetic Diversity of Deinanthe Caerulea Stapf., a Rare and Endemic Plant in China

“…In order to investigate the following questions: (1) What are the basic biological characteristics of D.caerulea seeds? (2) What is the viability of D.caerulea seeds? (3) Through experimental studies on the intrinsic characteristics of seeds and the germination of D.caerulea seeds under different temperature, light and moisture conditions in simulated environmental conditions, to investigate its adaptation mechanisms in the eld and further explore the causes of its endangerment, with a view to providing a reference for the conservation and exploitation of germplasm resources of D.caerulea.…”
