摘　　要：采用常规石蜡切片技术,对厚壁毛竹Phyllostachys edulis‘Pachyloen’和毛竹Phyllostachys edulis的叶片进行比较解剖研究,分析厚壁毛竹和毛竹叶表皮、叶肉细胞和梭形细胞等性状的解剖特征。结果表明,厚壁毛竹与毛竹叶的解剖结构组成基本相似;同一竹种不同年龄竹叶间各解剖因子存在明显差异,1年生新竹叶片的梭形细胞最为发达,导管截面积,输水截面积和韧皮部截面积也均高于其他年龄竹;而3至5年生竹的叶角质层厚度、维管束鞘细胞截面积大于1年生和2年生竹。The comparative anatomical structures of leaves between Phyllostachys edulis ＇Pachyloen＇ and Ph. edulis were conducted by paraffin section method. Anatomical characteristics of epidermis, mesophyll cell and fusoid cells in Ph. edulis ＇pachyloen＇ and Ph. edulis were analyzed. The results indicated that the anatomical structure ofPh. edulis ＇Pachyloen＇ and Ph. edulis are extremely similar, but there are obvious differences in each anatomical factor between different ages of the same species. One-year old new bamboo has the most developed fusoid cells; the vessel section area, conveyance water section area and phloem section area of one-year old bam- boo leaves are also higher than the others. The cuticle thickness of 3 years to 5 years old bamboo is much bigger than that of one year old and two years old bamboo.
