Studies on Flowering and Pollination Biology of Almond
摘要
Abstract
[Objective]Almond (Amygdalus communis L. ) is an important economic forest tree species in Xinjiang. Most of the almond varieties are allogamy plants and depend on the insect pollinators for their fruits set. The purpose of this study aims to make sure the composition of insect pollinator species and the efficiency of the dominant pollinators in almonds. [ Method ] Blossom characteristics and visitors' visitation were observed in the field during the flowering period. The pollinator efficiency was estimated by microscopic counting of the pollens deposited on the stigma and pollens remaining in anthers after a single visit to virgin flowers. [Result]The results showed that almond tree has a generalist pollination system, with bees, flies and butterflies being effective pollinators. In addition to the artificial breeding bees Apis mellifera and Osmia excavata, the wild bee Anthophora testaceipes is the main pollinator of local almond trees. There was no great difference in the deposited amount of pollens on the stigmas of the three kinds of bees, but they showed obvious difference of removing pollens in a single visit. Pollination efficiency of A. mellifera was lower than that of the other two bee species. Artificial breeding bees improved the fruit - setting obviously. [ Conclusion] Almond belongs to generalist pollination system. A. testaceipes is the safest and most effective pollinator among the pollination vectors.关键词
