摘要
选取10个品种的芍药作为研究对象,观察芍药叶片气孔的形态、分布规律,并对其气孔大小、气孔长宽比、表皮细胞密度、气孔密度及气孔指数等进行品种间比较及差异分析。结果表明:10个品种的芍药叶片气孔形态及分布规律一致。各项指标的品种内变异系数均较小。4个品种(1、2、8、9)的4项指标(气孔长度、宽度、长宽比及气孔指数)均没有差异。2个品种(1、9)的5项指标(气孔长度、宽度、长宽比、气孔密度及气孔指数)均没有差异。各项指标相比较,气孔宽度和气孔指数在各品种间变化较小。气孔密度与气孔长度呈反相关。结果不支持将气孔长度、宽度、气孔长宽比、气孔密度、气孔指数及表皮细胞密度作为芍药种或品种分类的依据。
The 10 Paeonia lactiflora varieties＇ stomatal width,length,stomatal density and epidermal cell density were measured,and the stomatal index and the ratio of length and width were caculated.Then the 10 Paeonia lactiflora varieties＇ stomatal morphology and distribution mutually were compared systematically.The results showed that the 10 Paeonia lactiflora varieties＇ stomatal morphology and distribution were uniform.There were no differences about 4 indexes（stomatal width,length,the stomatal index and the ratio of length and width）of 4 Paeonia lactiflora varieties（1,2,8 and 9）,and no differences about 5 indexes（stomatal width,length,stomatal density,the stomatal index and the ratio of length and width）of 2 Paeonia lactiflora varieties（1 and 9）.Compared with other indexes,the change of stomatal width and stomatal index were minimum.It showed inverse correlation between the stomatal length and the stomatal density.The results did not support the stomatal width,length,stomatal density and epidermal cell density,the stomatal index and the ratio of length and width as the classification basis of species or varieties.
