摘要
通过两年对板栗授粉特性的试验研究,发现虫媒授粉在板栗授粉过程中有着重要的地位,与对照样株自然授粉相比,隔离虫媒授粉的处理样株,柱头上的平均花粉数量减少32%～50%,平均球苞重减少22%～35%,空苞率高19%～23%,平均每总苞内坚果数少0.58～1.14个.
The pollination characteristics of Castanea mollissima were studied by experiments. It was showed that entomophilous pollination played a very important role in the pollinating process for Castanea mollissima plants. Compared to the natural pollination, the average quantity of pollens on the isolated stigmata was reduced by 32% - 50% ; and the average weight of the involucre was reduced by 22% - 35%, the ratio of empty involucre was increased by 19% -23%, and the mean number of nuts inside the involucre was decreased by 0. 58 - 1.14.
