| 摘 要： | 对哈尔滨地区东北杏(Anneniaca mandshurica(Maxim.)Skv.)有关落花落果现象进行调查,并对杏花器做了解剖学研究,以探求杏落花落果的原因。结果表明,杏落花落果现象严重,不同地点落花率在31%～100%之间;同株不同部位落花率在31%～65%之间。在花器结构上出现花被片萎缩、子房变小、花柱未伸长等现象。研究认为,杏落花落果及雌蕊败育与品种特性、树体营养状况、外界环境因子等有关。

| Abstract: | The article mainly investigated the flower and fruit drop and studied the flower organ anatomical structure in Anneniaca mandshurica, so that we could find the cause of flower and fruit drop. The result showed, it was serious to the flower and fruit dropping in Anneniaca mandshurica (Maxim.) Skv. The dropping rate is 31-100% at the different areas. The dropping rate is 31%-65% at the different position of the same plant. There are some flowers bedding shrinking, the germen smaller and flower pole fold at the flower organ structure. Through the above study, we believed that the flower and fruit dropping and pistile abortion is related to breed character, the nutrition state of the tree and the factor of environment in Anneniaca mandshurica. |
