摘要
孢子萌发与原丝体发育对于研究苔藓植物以及其他植物类群的系统发育与系统演化有着十分重要的作用。本文综述苔藓植物孢子萌发类型、原丝体发育特征以及环境影响因子等 ,还介绍了 2 0世纪90年代以来该领域研究的新进展 ,如人们以苔藓植物原丝体为实验材料进一步揭示Ca2 + ·CAM信号系统、、植物激素。
Spore germination and protonema development have been considered to be one of the important characters in the phylogeny and evolution of major groups of the bryophytes and other plant groups. This article reviews domestic and abroad studies on the types of spore germination,characteristics of protonema development and effects of environmental factors . It also presents the latest progress in this field from 1990s, such as the action mechanisms of Ca 2+ ·CAM signal system, plant hormones and light signal system in spore germination and protonema development of the bryophytes.
