- 摘要:
- 以‘大五星’枇杷为试材,研究了阴雨天气对枇杷柱头可授性和花粉活力的影响。结果表明:阴雨天气的持续均可以使枇杷柱头可授性和花粉活力不同程度地降低,降低授粉效率,对枇杷生产均有负面影响。此外柱头可授性检测表明,‘大五星’枇杷柱头可授期为开花当天至花后第5天,在此期任何一天只要天气晴朗,柱头随即恢复并具有较强的可授性,此特性可以一定程度地减少阴雨天气带来的负面影响。
- Abstract:
- The effects of rainfall on stigma receptivity and pollen viability were studied with ‘Dawuxing’ loquat.The results showed that the stigma receptivity and pollen viability decreased with the rainfall lasted days,which should reduce pollination efficiency and had the negative effects on production of loquat.Moreover,the detection results of stigma receptivity showed that the ‘Dawuxing’ loquat had a longer flower receptivity period until 5 days after anthesis,and the stigma receptivity could be recover from negative effects of rainfall by a sunny day which could reduced the negative effects of rainfall on production in some degree.
