松嫩平原芦苇的生物学和生态学特征

Biological and ecological characterization of Phragmites australis in Songnen Prairie

芦苇(Phragmites australis)在松嫩平原生存的历史久远而且分布广泛,通过查阅文献,本文分析了芦苇在松嫩平原特有的气候、土壤环境下形成的一系列生物学和生态学及遗传学特征,具体表现在形态解剖结构和光合、抗性生理特征,根茎的多种生物功能,抵抗盐碱、干旱和低温的能力,基因流,克隆间、种群间的遗传差异,表型可塑性、繁殖策略的可塑性以及生长调节和物质分配策略等方面。

Phragmites australis widely distributed in Songnen Prairie with long history and formed a series of biological, ecological as well as genetic characters contributing to accommodate to the specific local climatic and edaphic conditions. These characters included anatomy and ultrastructure, photosynthetic and resistance physiology, various functions of rhizome, resistance to different stresses including salinity, alkalinity, drought and cold, gene flow, genetic variation among clones and populations, phenotypic plasticity, plasticity in reproductive strategy as well as coordination of reed growth and biomass allocation strategy.
