Abstract
‘Conference’ (Pyrus communis L.) is a self-incompatible cultivar, although it can also set fruit parthenocarpically. Stimulating parthenocarpy through gibberellin (GA) applications increases the fruit set, but it may also negatively affect the fruit size and shape. The aim of this study was to investigate the effects of a bumblebee (BB) amendment in combination with a GA treatment on the fruit set and fruit shape of ‘Conference’ pears. In the first experiment, we applied three treatments (GA, GA + BB & control) in a ‘Conference’ monoculture. In the second experiment, we applied two treatments (GA & GA + BB) in a ‘Conference’ orchard inter-planted with ‘Concorde’ as pollinizer trees. Both experiments showed that the GA application and bumblebee supplementation did not affect the fruit set. However, the BB treatment resulted in significantly higher amounts of normally shaped pears. Trees closer to the bumblebee hive had more normal shaped pears than trees further away.
“会议”(Pyrus communis L.)是一种自交不亲和的品种,尽管它也可以单性结果。施用赤霉素(GA)刺激孤雌核可增加坐果量,但也可能对果实大小和形状产生负面影响。本研究的目的是研究大黄蜂(BB)改性剂与GA处理相结合对“会议”梨的坐果和果实形状的影响。在第一个试验中,我们在“会议”单一栽培中应用了三种处理(GA, GA + BB和对照)。在第二个试验中,我们在“会议”果园中间种了“协和”作为授粉树,采用了两种处理(GA和GA + BB)。两项试验均表明,GA施用和大黄蜂添加对坐果没有影响。然而,BB处理导致正常形状梨的数量显著增加。靠近大黄蜂蜂巢的树比远离蜂巢的树有更多正常形状的梨。
