摘要
翅果油树为国家2级珍稀濒危保护植物,为了深入探讨翅果油树濒危的原因,提高其经济及社会价值。试验对其叶片表皮形态结构、叶解剖结构特性进行了初步研究。结果表明,相对于同科植物沙枣、沙棘来说,其气孔少、角质层厚度比较薄、叶片栅栏组织与叶肉组织的比例也比较小。作为旱生植物的翅果油树较同科旱生植物的叶蒸腾效果弱,抗旱性就相对弱一些,这可能是其成为濒危物种的重要原因之一。
Elaeagnus Mollis is among the list of rare endangered State-level II plants under protection. In order to understand the endangered causes of Elaeagnus Mollis, improve it＇s economic and social values, this paper studied the morphological structure of leaf epidermis and leaf characteristics of the anatomical structure. The result showed that, compared to the same family of plants Elaeagnus angustifolia L and Hippophae rhamnoides, the pore was small, the cuticle thickness was relatively thin, leaf mesophyll palisade tissue and the proportion of organizations was also small. Thus it can be seen that Elaeagnus rnollis has weaker leaf transpiration, and hence weaker drought resistance. This may be one of the very causes for Elaeagnus Mollis to become endangered.
