The drought resistance characteristics of leaf anatomical structure of Hedysarum mongolicum, Salix psammophila, Caragana microphylla, Caryopteris mongholica and Atriplex canescens were observed under microscope by paraffin-cross section method.
本文以杨柴、沙柳、小叶锦鸡儿、蒙古莸、四翅滨藜5种沙生灌木的成熟叶片为试验材料,采用石蜡制片法,应用光学显微技术,观察了其叶片解剖结构抗旱特征,测定了叶片厚度、角质层厚度、栅栏组织厚度、主脉导管壁厚度、主脉导管直径等抗旱指标,并对上述抗旱指标进行主成分分析和隶属函数综合评价,分析各树种的抗旱机理,比较抗旱能力的差异,结果表明: 1。
2) anatomical structure index of leaves
叶片解剖结构指数
1.
The computing formula of anatomical structure index of leaves (Y) was made to be Y=0.
结果表明,50份种质材料的栅栏组织厚度与海绵组织厚度比值(X1)、上表皮厚度与海绵组织厚度比值(X2)、栅栏组织厚度与总厚度厚度比值(X3)、角质层厚度与总厚度比值(X4)以及海绵组织厚度与总厚度比值(X5)等都存在显著差异;提出叶片解剖结构指数(Y)的计算公式为Y=0。
