以红里肥城桃、白里肥城桃为受粉母本,用与肥城桃混栽的6个品种作为授粉父本进行授粉试验,连续3年调查其坐果率,研究肥城桃与不同品种花粉授粉的特异性(亲和性)。结果表明:红里肥城桃可自花授粉结实,授白里肥城桃花粉亦可结实;白里肥城桃可自花授粉结实,授红里肥城桃花粉亦可结实;红里肥城桃、白里肥城桃用其他品种授粉均不结实。研究表明肥城桃群体存在授粉特异性,人工辅助授粉可有效提高坐果率。
Feili peach and Baolili peach were pollinated with 6 varieties mixed with Feicheng peach as pollination parents. The fruit setting rate was investigated for 3 consecutive years, and the pollination of Feicheng peach and different varieties of pollen Specificity (affinity). The results show that the red peach peach can be self-pollination and fructified, and the white peach peach pollen can also be strong; Feicheng peach pollination with other varieties are not strong. Studies have shown that there are pollination Feicheng peach population specificity, artificial pollination can effectively improve the rate of fruit set.
