摘要
以3个月苗龄的海芒果和黄槿实生苗为试材,进行不同盐分浓度胁迫试验,通过对苗高、地径和根、茎、叶干重进行测定,并分析叶片中叶绿素、丙二醛含量以及叶片相对电导率,综合评价分析了两种半红树植物的耐盐性。结果表明:海芒果可以在盐分浓度(盐质量/土壤质量)低于0.8%时维持生长,黄槿可在盐分浓度低于0.4%时生长,海芒果耐盐性优于黄槿。
Three-month-old seedlings of two kinds of semi-mangrove species, Cerbera manghas and Hibiscus tiliaceus were tested with salt gradient concentrations, and the seedling height, basal diameter, the dry weights of root, stem and leaf, the content of chlorophyll, malondialdehyde in leaves and the relative conductivity of leaf were measured. A comprehensive analysis was carded out to compare the salt tolerance of the two species. The results show that C. manghas could maintain growth when salt content （mass of salt/mass of soil） below 0.8 %, and H.tiliaceus could grow when salt content below 0.4 %. C. manghas is better than H.tiliaceus in aspect of salt tolerance.
