印楝叶解剖结构与抗旱性关系初步研究

A Study on the Relationship between Anatomical Structure of Leaves and Resistance Drought of Neem (Azadirachta indica)

对印楝叶解剖结构的观察和分析 ,研究发现印楝叶具旱生结构特征 :a)较厚的角质层 ;b)有大量贮水细胞 ;c)栅栏组织发达 ,初步具有双栅叶特征 ;d)叶组织细胞排列紧密 ,栅栏组织细胞密度大 ;e)维管系统发达 ,具维管束鞘的伸展区 ;f)表皮层较厚 ,气孔密集 ;g)含晶细胞分布广 ,数量多。从解剖学的角度证实印楝是一种抗旱植物 。

By observing and analyzing the leaves anatomical structure of Neem (Azadirachta india),it was found that Neem possessing the characters of xeromorphic structure,i.e.a) thick cuticle; b) a large amount of water storage parenchyma; c) flourishing palisade tissue; d)leave tissues forming tight; e) developed conducting tissue; f) thick epidermis and dense stomata; g)a lot of crystal cells.So Neem is belonging to drought resistant plants,which are adaptable to the dry and hot valley area in China
