苹果授粉特性研究进展

ADVANCES OF STUDY ON THE POLLENING CHARACTERISTICS OF APPLE TREES

苹果是异花授粉树种 ,授粉是影响其果实品质的重要因素。花粉的形态、生活力等直接影响授粉效果 ;雌蕊的生长发育对受精有着重要的影响 ;柱头有效授粉期的长短决定授粉品种的选择 ;光照、气温、空气湿度、风以及传粉方法都对授粉效果有着重要的影响。授粉程度影响果实形状和大小 。

Apple trees are cross-pollinated plants, and pollination is an important factor which affects the fruit quality .Pollination effects are directly affected by pollen shape and its viability . The development of pistil plays an important part in fertilization choosing pollinated variety is determined by the length of effective pollination period. Pollination results are also affected by the illumination ,air temperature ,air humidity ,wind speed and pollinating method. The degree of pollination affects the fruit shape and its size.The characteristics of pollinated variety affect the fruit shape index and other fruit quality aspects.
