在自交不亲和李的商业果园中进行试验，其授粉和果实产量通常是这种早花作物的真实的问题。为此，我们在果园里引进了蜜蜂、石匠蜂和熊蜂。通过在果园的五个采样区域每天计数3小时访问主品种的花的次数来评估传粉昆虫在开放领域中的效率，没有检测到熊蜂访问主品种的花。另外两种传粉者。表现出觅食活动，减少从各自的出发点的距离增加：在每个采样区，访问的总次数是密切相关的果实数量和总产量。在果实品质方面没有发现显著差异。访问最多的地区的果实产量非常接近通过花粉喷雾机械授粉后获得的产量。还在笼中的树木上进行了pollution，分别使用不同的昆虫，以评估其各自的效率。(C)1998年Elsevier Science B.V.
Trials were performed in a commercial orchard of self-incompatible plum, whose pollination and fruit yield often are a real problem in this early blooming crop. For this reason we introduced in the orchard honey bees, mason bees, and bumble bees. The efficiency of pollinator insects was evaluated in the open field by counting-for 3 h a day in five sampling areas of the orchard-the number of visits to the flowers of the main cultivar, No bumble bees were detected visiting the flowers of the main cultivar. The other two pollinators. showed a foraging activity which decreases by increasing the distance from their respective starting points: In each sampling area, the total number of visits was strongly related to fruit number and total yield. No significant differences were detected regarding fruit quality. Fruit yield of the most visited areas was very close to that obtained after mechanical pollination by pollen spray. Pollination was also performed on caged trees, using the different insects separately in order to evaluate their respective efficiency. (C) 1998 Elsevier Science B.V.
