引进美国扁桃品种间授粉坐果率的比较

[目的]确定引进美国扁桃品种间授粉搭配最佳的组合.[方法]以Nonpareil、Sonora、Mission、Thompson、Nepulusultera、Butte 6个品种花粉对其坐果率的影响为研究对象.[结果]用Nonpareil、Sonora、Mission、Thompson、Butte对Nepulusultera授粉,其平均坐果率为31;、19;、14;、15;和29;.用Sonora、Mission、Thompson、Nepulusultera、Butte对Nonpareil授粉,其平均坐果率为35;、32;、22;、31;和38;.用Nonpareil、Mission、Thompson、Nepulusultera、Butte对Sonora授粉,其平均坐果率为37;、31;、31;、33;和20;.[结论]Sonora、Butte、Nonpareil为Nepulusultera最佳授粉品种, Mission、Sonora、Butte、Nepulusultera为Nonpareil最佳授粉品种,Nonpareil、Thompson、Nepulusultera、Mission为Sonora最佳授粉品种.

Comparison on Fruit Setting Percentage in Introduced American Almond with Pollination between Varieties

【Objective】To confirm the optimum combination of the introduced American almonds with pollination between varieties.【Method】Taking the six varieties of Nonpareil,Sonora,Mission,Thompson,Nepulusultera and Butte and study the effect of their pollens on fruit setting percentage.【Result】The result shows that: the average fruit setting percentage were 31%,19%,14%,15% and 29% respectively,by Nepulusultera pollinated with Nonpareil,Sonora,Mission, Thompson and Butte;the average fruit setting precentage were 35%,32%,22%,31% and 38%,by Nonpareil pollinated with Sonora,Mission,Thompson,Nepulusultera and Butte;the average fruit setting percentage were 37%,31%,31%,33% and 20%,by Sonora pollinated with Nonpareil,Mission,Thompson,Nepulusultera and Butte.【Conclusion】Sonora,Butte and Nonpareil are the optimum pollination varieties for Nepulusultera;Mission,Sonora,Butte and Nepulusultera are the optimum pollination varieties for Nonpareil;Nonpareil,Thompson,Nepulusultera and Mission are the optimum pollination varieties for Sonora.
