| 摘 要： | 采用盆栽试验，在高温胁迫条件下,通过测定4种地被植物的细胞质外渗率、丙二醛含量、超氧化物歧化酶活性、过氧化物酶活性和脯氨酸、可溶性糖、可溶性蛋白质及叶绿素的含量等生理指标，利用隶属函数法对4种地被植物进行了耐热性综合评价。通过综合隶属函数值评定的耐热性强弱顺序为:广西过路黄Lyaimachia alfredii>花叶过路黄L.christinae var huaye>聚花过路黄L.congestiflora>金叶过路黄L.nummularia‘Aurea’，这一结果与4种植物的实际表现相一致。结果表明，模糊隶属函数法可以避免单一指标的片面性，能较全面地评价地被植物的耐热性。

| Abstract: | The high-temperature tolerance index of four ground covering plants under different heat stress was studied.Through measuring physiological high-temperature tolerance characteristics such as relative permeability of plasma membrane,content of MDA,SOD and POD activity,proline,chlorophyll,soluble sugar and soluble protein content;and a comprehensive evaluation on high-temperature tolerance of different species of four ground covering plants was given based on subordinate function values analysis.The results i... |
