摘要
普通芦苇广布于世界各地异质性生境,通常表现出遗传、表型和染色体数目上的高度变异性以及生殖策略的灵活性。本文综述了近年来有关异质生境下芦苇的表现和响应,分析其适应异质生境的主要策略是表型可塑性和遗传变异,以期为芦苇适应策略的研究提供新的研究思路。
P.australis is a cosmopolitan species distributed in heterogeneous habitats and shows large variation in genetic material,morphology and chromosome numbers,as well as plasticity in reproductive strategy.This article overviewed the researches on the phenomenon and responses of P.australis in heterogeneous habitats in recent years,and thought that P.australis＇ main adaptive strategies were phenotypic plasticity and genetic variation.This study aimed to provide more research thought for the research of adaptive strategies of Phragmites australis.
