温室内文冠果授粉和坐果情况调查

Investigation on Gollination and Fruit Setting of Xanthoceras Sorbifolium in Greenhouse

在温室条件下,5种文冠果的可孕花比例均大于90%,在没有人工授粉的情况下,对其授粉情况进行调查,发现文冠果1号在自然情况下授粉率最高,可达64%,且坐果率也最好,可达21%;2号授粉率22%,坐果率较低,只有5%;3号、4号和5号授粉率均低于2%,坐果率几乎为0。本试验对文冠果实现丰产进行了源头性的探讨,为实现文冠果的产业化发展提供了理论基础。

Under greenhouse conditions,the fertile flower ratio of five species of Xanthoceras sorbifolium Bunge was more than 90%.In the absence of artificial pollination,the pollination of Xanthoceras sorbifolium Bunge was investigated.The result showed that the pollination rate of No.1 was the highest under natural conditions,up to 64%,and the fruit setting rate was the best,up to 21%.The pollination rate of No.2 was 22%,and the fruitsetting rate was only 5%.The pollination rates of No.3,No.4 and No.5 were all lower than 2%,and the fruit setting rates were almost zero.In this experiment,the source of high yield of Xanthoceras sorbifolium was discussed,which provided a theoretical basis for the industrialization development of Xanthoceras sorbifolium.
