摘要
授粉试验表明,‘大红杏’、‘二红杏’、‘媳妇杏’和‘串枝红杏’均为自花不实品种,彼此间相互授粉时存在着结实率的差异。在栽培条件和气象条件相同情况下,自花不实品种结实率低的主要原因是缺乏合适的授粉品种。 杏品种间存在着杂交不亲和现象,‘二红杏’与‘串枝红杏’、‘媳妇杏’与‘串枝红杏’以及‘大红杏’与‘串枝红杏’之间表现为单方不亲和;‘大红杏’与‘二红杏’、‘媳妇杏’与‘大红杏’之间表现为交互不亲和。
The pollinating test shows that such apricot varieties as 'Da Hong Xing', 'Er Hong Xing', 'Xi Fu Xing' and 'Chuan Zhi Hong' are self-unfruitful. Only by planting suitable pollenizers can they set fruits.
By using the pollen of 'Chuan Zhi Hong' to pollinate 'Da Hong Xing', 'Er Hong Xing' and 'Xi Fu Xing' they can set fruits while 'Chuan Zhi Hong' was pollinated by the pollen of the other three cannot set fruits at all. This fact indicates that there is the one-sided incompatibility between some apricot varieties.Between 'Da Hong Xing' and 'Er Hong Xing' or between 'Da Hong Xing' and 'Xi Fu Xing' the reciprocal pollination cannot set fruits. Thn phenomenon presents that the reciprocal incompatibility exists among some apricot varieties.
The experiment has proved that in the varieties of apricot exists the self-incompatibility series controlled by the multipleallele like sweet cherries.
