摘要
观察了桃亚属6个种139份材料的气孔长度和宽度。结果表明,不同种间气孔长度和宽度相差较小,光核桃长度非常一致,其变异系数为0,栽培种的品种之间气孔大小差异更小。栽培种的气孔长、宽均呈正态分布,依概率分级方法将气孔长度和宽度分为5个等级。
The leaf stoma length and width of 139 materials （seedlings）of six species of peach （Prunus persica Batsch）were examined. There was a large difference among different species and a small difference among different cultivars （seedlings）. The stoma length of P. mira was so identical that its variation coefficient was O. The distributions of stoma length and width conformed tothe nomal distribution. Stoma length and width could be divided, in a unified way, into 5 grades.
