采用酸解离法对富士系苹果叶片气孔进行了观察,从而对富士芽变品种及不同的变异性状进行了鉴别。结果表明:叶片气孔密度的变化范围在91~173个/mm2,保卫细胞长度变化在25.8~32.4μm之间;保卫细胞宽度变化在18.4~24.2μm之间,芽变品种的保卫细胞的宽度有变长的趋势。通过聚类分析表明,短枝型芽变品种的气孔密度显著低于原品种的气孔密度,可利用气孔密度进行短枝型芽变品种的鉴定;着色型、早熟型及大果型变异的品种在3个类群中都有分布,不能用气孔性状来鉴别这类变异。
The acid-dissociation method was used to observe the leaf stomatal of Fuji apple leaves, and the Fuji bud varieties and different variation traits were identified. The results showed that the stomatal density varied from 91 to 173 cells / mm2, the length of guard cells varied from 25.8 to 32.4μm, the guard cell width varied from 18.4 to 24.2μm. The width of guard cells in budding varieties was The longer the trend. The results of cluster analysis showed that stomatal density of spur type varieties was significantly lower than that of the original varieties, and stoma density could be used to identify varieties of spur type. Varieties of pigmented, precocious and large fruit varieties There are distributions among the three taxa, and stomatal traits can not be used to identify such variations.
