| 摘 要： | 在自然条件下,对西葫芦幼苗不同节位叶片的形态解剖结构进行了研究.结果表明:节位由上至下,叶片上、下表皮细胞密度及气孔密度呈下降趋势,表皮细胞及气孔大小呈上升趋势,上部叶片栅栏组织厚度与下部叶片栅栏组织厚度之间存在极显著差异,栅栏组织厚度与海绵组织厚度比值在0.84～0.88之间.不同节位之间西葫芦单叶重、叶长及叶面积之间具有极显著相关性.

| Abstract: | The anatomic structures of Cucurbita pepo L.seedling leaves in different nodes under the natural condition were studied.The result showed that as the node from top to bottom,the density of epidermal cell and stoma became lower and the size of epidermal cell and stoma had a tendency of increase.There were extremely conspicuous differences of palisade tissue thickness between sup leaves and subjacent leaves,and the thickness proportionality of palisade tissue and spongy tissue was between 0.84~0.88.There were... |
