葡萄品种资源落花落果率的调查与分析

Investigation and analysis of the flower and fruit drop rates in different grape variety resources

落花落果在葡萄生产中时常发生。调查落花落果将会为了解品种固有特性,针对不同葡萄品种的特点进行花果管理提供参考,也可为品种资源的利用以及育种亲本的选择提供依据。本文选取7个野生品种,29个鲜食品种,对各个葡萄种质进行的落花落果率调查分析。结果表明:不同种质间的落花落果率差别较大,其中野生种的落花落果率较高,平均落花率为74.17%,平均落果率为47.89%;其次是欧美种,平均落花率为53.82%,平均落果率为51.03%;欧亚种的平均落花率为61.6%,平均落果率为44.07%。

Blossom and fruit dropping often occur in grape production.The investigation of that will understandthe inherent characteristics of different grape varieties,and provide reference for management of flower and fruitaccording to the characteristics of different varieties.It can also provide the basis for the utilization of varietyresources and the selection of breeding parents.7wild varieties and29fresh varieties were selected to investigatethe fruit and flower falling rate in the paper.the results showed that there were the difference between germplasms,the flower and fruit falling rate of wild varieties were higher,the average flower falling rate was74.17%,the averagefruit drop rate was47.89%;Secondly,hybrids of V.vinifera and V.labrusca,the average flower falling rate was53.82%%,the average fruit drop rate was51.03%;the Vitis vinifera L,average flower falling rate was61.6%,theaverage fruit drop rate was44.07%.
