不同品种花粉和授粉量授粉对砀山酥梨果实萼片的影响

为改善砀山酥梨果实外观,提高果实品质,以不同授粉品种和授粉量给砀山酥梨授粉,授粉后立即套袋,10 d后去袋,于生理落果结束后,调查果实萼片脱落情况.结果表明,有73.0%的处理3序位果实脱萼率显著高于4、5序位的脱萼率或没有显著差异.其中,早美酥的全部处理、其他供试品种的1∶2和1∶4混合花粉的全部处理3序位的果实脱萼率都显著高于4、5序的脱萼率.以黄宝石或早美酥的1∶4混合花粉点授3、4、5序位花朵,可以分别获得73.2%、65.8%的果实脱萼率.若以50%为坐果率要求,用早美酥1∶6混合花粉点授花序中3、4、5序位花朵,可以获得80.1%的果实脱萼率.
