前言葡萄四倍体品种‘康能玫瑰’、‘森田尼’(均为欧亚种)、‘巨峰’(欧美杂种)以及‘先峰’(巨峰×康能玫瑰)等,常表现严重落花,有核果不足。其原因之一,是因为伸长到花柱里的花粉管在中途就停止生长,所以,很难进行受精。冈本等对‘先峰’葡萄品种采用异花授粉、重复授粉、蕾期授粉、老花授粉以及花穗高温处理等 Preface Grape tetraploid varieties ’Kangneng Rose’, ’Morita Ni’ (all Eurasian species), ’Jufeng’ (European and American hybrids) and ’Xianfeng’ (Kyoung × Kangon Rose) There is not enough drupe. One reason for this is that pollen tubes that extend into the style stop growing halfway, making them difficult to fertilize.
