摘要
薹草属(Carex)隶属于莎草科,是被子植物中最大的属之一.该属植物种类繁多,可见于林下、林缘、湿地、草甸等多种生境,分布较为广泛.该属内许多薹草种株型优美,抗性较强,在园林植物造景、盐碱地绿化和湿地植被修复等方面起着重要的作用,因而近年来逐渐受到人们的关注.基于此,本文从薹草属植物的系统分类、抗逆性与栽培繁殖3个方面对其分类依据、新种发现情况、不同非生物因子的影响以及不同繁殖方式和养护特点进行了总结,并提出了研究展望.以期为薹草属植物应用于园林绿化与生态修复提供理论依据,也为薹草属植物后续在抗逆机理、种子萌发和快速繁殖等方面深入研究提供思路.
Abstract
Carex(Cyperaceae)is a vast genus,representing one of the largest within angiosperms.These sedges exhibit remarkable ecological breadth,colonizing diverse habitats including forests,forest margins,wetlands,and meadows.Many Carex species possess aesthetically pleasing morphologies and exceptional stress tolerance.Consequently,they play crucial roles in landscape design,saline-alkali land revegetation,and wetland restoration efforts.This growing appreciation has spurred a surge in scientific interest in recent years.Building upon this momentum,the present research offered a comprehensive review of Carex research across three key aspects:Systematic classification,stress resistance,and cultiva-tion and reproduction techniques.We summarized current literature on these themes,highlighting the dis-covery of novel species,the influence of abiotic factors,and the characteristics of various breeding and con-servation methods.Furthermore,we proposed promising avenues for future research.This review aims to establish a theoretical foundation for the application of Carex in landscaping and ecological restoration,pro-viding valuable insights for future investigations into stress resistance mechanism,seed germination,and rapid propagation techniques.
