摘  要：
利用石蜡切片法以及徒手切片法,对雪柳(Fontanesia fortunei Carr.)、连翘(Forsythia suspense Vahl.)和小叶丁香(Syringa microphylla Diels.)的叶片进行了形态解剖学观察。结果表明,三种植物均为异面叶,但是栅栏薄壁组织层数、栅海比以及叶片主脉的结构有着明显的差异性。三种植物的气孔密度的排列顺序为:雪柳>连翘>小叶丁香;栅海比的排列顺序为:雪柳>连翘>小叶丁香。由此得出,三种植物的抗旱性雪柳最强,连翘其次,小叶丁香最差。

摘  要：
The paraffin section and hand sliced methods were used to study on anatomical structure of leaves of Fontanesia fortunei Carr.,Forsythia suspense Vahl.,and Syringa microphylla Diels.The results showed that the leaf structure of three species were bifacial type,but the significant difference existed among the four in the aspects of the number of the palisade tissue,the ratio of palisade tissue to spongy tissue and primary vein structure.It showed that the order of the stomatal density was Fontanesia fortunei Carr.>Forsythia suspense Vahl.>Syringa microphylla Diels.;the order of the ratio of palisade tissue and spongy tissue in three species was Fontanesia fortunei Carr.>Forsythia suspense Vahl.>Syringa microphylla Diels.The drought-resistant ability of Fontanesia fortunei Carr.was the strongest among these three plants,the second was Forsythia suspense Vahl.,and the thinnest was Syringa microphylla Diels.
