测定了桃的72个品种（系）的花粉量以及其中大部分品种的花药重量，结果表明，花粉量的总体分布为两个分布的集合分布，花粉量和花药重量极显著相关（r＞0．95），一些品种的花粉量差异显著或极显著。将品种的花粉量（粒·花粉-1）分为：无可育花粉（＜350）、少（351～750）、中（751～1200）、多（1201～1500）、极多（＞1501）。正常花粉量的品种花粉发芽率没有显著差异。
The results showed that the overall distribution of pollen quantity was the distribution distribution of two distributions, and the pollen quantity and the anther weight had a very significant correlation (r> 0 .95), some varieties of pollen amount difference was significant or very significant. Pollen grains (pollen-pollen-1) were divided into four groups: pollen without pollen (<350), pollen with less (351-750), medium (751-1200) ). Pollen germination rate of normal varieties of pollen did not differ significantly.
