摘  要:
以4种鸭趾草科屋顶绿化植物为试验对象,设置8种不同的处理温度,采用电导率法,并结合Logistic方程,计算出4种植物在梯度高温处理下的细胞伤害率和高温半致死温度,评价其耐热性.结果表明:4种植物的细胞伤害率随处理温度的升高而呈"S"型曲线增长趋势,经显著性检验,符合Logistic方程,其耐热能力从小到大依次为假紫万年青毛叶变种(Belosynapsis ciliata var. vilosa)<假紫万年青(Belosynapsis ciliata)<牛轭草(Murdannia loriformis)<细竹篙草(Murdannia simplex).与屋顶绿化应用的其他科属植物的高温半致死温度比较,4种鸭跖草科植物的耐热性普遍较好,从耐热性的角度而言,4种鸭跖草科植物是潜在应用于屋顶绿化的优良种质,且在华南地区广泛应用成功的可能性较高.

摘  要:
Four species of Commelinaceae were selected as test objects for roof greening,and treated with eight different temperature. With conductivity method and Logistic equation,the heat resistance of four plants were evaluated by cell damage rate and semi-lethal temperature under different temperature. The results showed that with the increase of treatment temperature,the cell hurt rate of four plants showed an"S"curve,and the significant test of which fitted Logistic equation. The heat resistance of four species of plant followed the order: Belosynapsis ciliata var. vilosa < Belosynapsis ciliata < Murdannia loriformis
