摘要:
 采用石蜡切片技术，对筇竹(Qiongzhuea tumidinoda)叶片进行了解剖学研究，并对其显微结构进行分析。结果表明，筇竹叶片表皮细胞长5.22～20.38 μm，宽3.90～14.68 μm；泡状细胞长14.98～34.88 μm，宽9.99～32.97 μm；叶肉细胞长7.67～25.20 μm，宽2.68～13.86 μm；薄壁细胞长5.68～13.74 μm，宽2.70～10.09 μm，厚壁细胞长3.11～11.64 μm，宽1.83～8.19 μm。筇竹叶片在解剖结构上存在变异，各指标变异系数为9.30%～26.08%，除个别指标外，变异系数均在15%以上；构建了筇竹叶片各类细胞长宽之间的回归方程，可用各类细胞的宽度对各类细胞的长度进行预测。发现仅少数指标之间存在差异，多数指标不同年龄之间的差异并不显著，筇竹秆龄并没有对叶片形态特征产生明显差别。
Abstract:
 An anatomical study of Qiongzhuea tumidinoda was carried out by using paraffin section technique.The microstructure of Q.tumidinoda leaves was analyzed.The results showed that the length of the epidermal cell was 5.22-20.38 μm,the width was 3.90-14.68 μm,the length of the bulliform cell was 14.98-34.88 μm,the width was 9.99-32.97 μm,the mesophyll cell length was 7.67-25.20 μm,the width was 2.68-13.86 μm.The parietal cell length was 5.68-13.74 μm,the width was 2.70-10.09 μm,the thick-walled cell was 3.11-11.64 μm,and the width was 1.83-8.19 μm.The variation coefficients of the indexes were 9.30%-26.08%.Except for the individual indexes,the coefficient of variation was above 15%.The regression equation between the length and width of the cells was established.The length of all kinds of cells could be predicted by the width.It was found that only a few differences between the indicators,most of the differences between the different ages were not significant.Q.tumidinoda age had no significant effects on leaf morphological characteristics.
