- 摘要:
- 采用人工胁迫盆栽法,对14种地被植物进行25%海水、50%海水2种胁迫处理,根据植株胁迫处理后的生长表现、盐害指数、盐害率、细胞膜透性等指标进行综合分析,比较耐盐性。结果表明:14种地被植物的耐盐性存在差异,耐盐性可以分为4个等级,其中沙地柏(Sabina vulgaris)、八宝景天(Sedum spectabile)、景天三七(Sedum aizoon)耐盐性最强,马蔺(Iris lactea var.chinensis)、麦冬(Liriope spicata)、五叶地锦(Parthenocissus quinquefolia)、射干(Belamcanda chinensis)较强,金酒吧芒(Miacanthus sinensis ‘Gold Bar’)、狼尾草(Pennisetum alopecuroides)、金娃娃萱草(Hemerocallis fulva ‘Golden Doll’)、玉带草(Phalaris arundinacea‘Picta’)中等,丰花月季(Rosa cvs)、荷兰菊(Aster novi-belgii)、青绿苔草(Carex leucochlora)最弱。
- Abstract:
- By used the method of artificial stress potting,14 species ground cover plants were stress treated by two kinds treatments of 25% and 50% seawater concentration.Comprehensive analysis was made by the growth performance,the salt injury index,the salt injury rate,the cell membrane permeability and other index of plants which were stess treated.The results showed that salt tolerance of the 14 ground cover plants varied and classified into four grades,Sabina vulgaris,Sedum spectabile and Sedum aizoon were the strongest;Iris lactea var.chinensis,Liriope spicata,Parthenocissus quinquefolia and Belamcanda chinensis were stronger;Miacanthus sinensis ‘Gold Bar’,Pennisetum alopecuroides,Hemerocallis fulva ‘Golden Doll’and Phalaris arundinacea ‘Picta’ were middle;Rosa cvs,Aster novi-belgii and Carex leucochlora were the weakest.
