摘要
采用闽引圆叶决明(Chamaecrista rotundifolia)为材料进行盆栽低温试验,栽培温度分别控制在5℃、10℃、15℃、25℃(CK),研究其在低温气象条件下的生长变化,结果表明低温使闽引圆叶决明生长受阻,其株高、根长,地上部重、根重和总生物量都表现为明显降低,根冠比下降,根系活力下降。
In order to study the growth change under the meteorological condition of low temperature,we focused on the case study of low temperature,which were controlled at 5℃,10℃,15℃ and 25℃(CK),with chamaecrista rotundifolia.The results indicated that the growth rate of chamaecrista rotundifolia decreased in low temperature,and the plant height,root length,dry mater weight of shoot,root weight,total biomasses,root-top ratio and root activity also obviously decreased in low temperature.
