摘要
应用徒手切片法对金银忍冬叶进行了解剖学的初步研究,旨在为其解剖学、分类学及生药学的研究提供相应基础。结果表明:金银忍冬叶为异面叶,上下表皮细胞各一列,上表皮没有气孔,下表皮气孔分布的气孔指数为14.3%~25%,多为不定式气孔,栅栏组织为1层,含叶绿体较多,海绵组织内含草酸钙簇晶,表皮细胞外壁加厚形成角质层,皮层有厚角组织,主脉为外韧维管束等。上述特征说明金银忍冬叶的解剖结构与其生理功能及生态环境是相适应的。
Preliminary anatomical structure of leaf from Lonicera maackii was studied by the methods of barehanded section in order to provide the basis for anatomy,systematic and pharmacognosy.The results show that:leaf of L.maackii is bifacial leaf,the upper and lower epidermis are 1 layer,the stomata only exist in lower epidermis,stomatal index is 14.3%~25%,most stomata are anomocytic type,palisade tissue is 1 layer with a lot of chloroplasts,there are cluster crystal of calcium oxalate in spongy tissue,the main vein of leaves is collateral vascular bundle.There is collenchyma in cortex.The characters mentioned aboved show leaf of L.maackii adapted well to the physiological function and ecological environment.
