| 摘 要： | 通过石蜡切片法对亮叶忍冬,蔓生紫薇叶片的解剖结构进行了观察,并对叶片厚度、主脉厚度、栅栏组织厚度、海绵组织厚度、第1层栅栏组织细胞密集度、栅栏组织厚/海绵组织厚、栅栏组织/叶肉组织、上下表皮厚度等抗旱性结构指标上进行检验比较,方差分析。结果表明:亮叶忍冬,蔓生紫薇在水分胁迫下,叶片的解剖结构与对照在叶片厚度、主脉的厚度等抗旱性指标上均极显著变薄,而栅栏组织与叶肉组织比、栅栏组织与海绵组织比、第1层栅栏组织密集度上,2种处理及与对照均没有显著差异;亮叶忍冬、蔓生紫薇2种植物间叶片的解剖结构在各抗旱指标上表现出极显著的差异,其抗旱性为亮叶忍冬蔓生紫薇。

| Abstract: | Observed the leaf tissue para meters between Lonicera japonica Thumb.and Lagerstroemia indica 'Sumer and Sumer' with the paraffin wax slices.Through the comparison and variance analysis of the drought resistance on the thickness on the leaf,major vascular tissue,palisade tissue,spongy tissue,the density of first floor cell palisade tissue,palisade tissue/spongy tissue,palisade tissue/mesophyll tissue,upper and lower epidermis,etc.The results showed that the drought resistance on the leaf tissue para meters ... |
