Variation in leaf and fine root traits with altitude in Abies georgei var.smithii in Mt.Shergyla
叶片和细根是植物对环境变化响应的主要功能器官,在气候变化趋势下,研究其随环境梯度的变化,对理解植物对环境的适应策略具有重要意义.本文是在色季拉山急尖长苞冷杉分布区,按海拔梯度(3800、3900、4000、4100、4200、4300、4400m)选择7个典型样地,在样地内对其叶片基本特征、叶绿素含量、比叶重和细根特征(0-60cm)等参数进行了测量.结果表明:(1)随海拔梯度升高,急尖长苞冷杉叶片叶面积减小、叶片厚度增加、叶绿素含量逐渐降低、比…查看全部>>
The relationship between plant and environment is one of key issues in the field of ecology.Plant functional traits and the responses of some traits to environment have been of interest to scholars since the 19th century.Studies on the changes in plant leaf and fine root traits and their correlation with elevation gradient explain how plants respond and adapt to a changing environment.Leaf length,width,thickness,area,specific leaf weight,chlorophyll content,…查看全部>>
