摘要:

为提高柑橘杂交坐果率,本试验以柑橘品种红美人为母本,以甘平和鸡尾葡萄柚为父本配制杂交组合,研究赤霉素喷施时期对柑橘杂交果品质及坐果率的影响。结果表明,红美人×甘平和红美人×鸡尾葡萄柚杂交组合授粉后喷施赤霉素的坐果率分别为43.30%和46.36%,均显著(p<0.05)高于对照(21.20%、27.44%)和幼果喷施处理(23.93%、29.61%)。2个杂交组合授粉后喷施处理的果实固酸比为26.17、26.21,幼果喷施处理的果实固酸比为23.35、24.40,均显著高于对照(18.92、21.77)。授粉后1~2 h喷施50 mg·L-1赤霉素能显著提升杂交果的坐果率和果实内在品质,对父本花粉生活力差异较大的杂交组合均表现出相同的促进作用。在柑橘杂交育种过程中,采用授粉后1~2 h喷施50 mg·L-1赤霉素来提升杂交果坐果率的方法可行。

Abstract:

In order to improve the fruit setting rate for citrus hybridization,two hybrid combinations were prepared with the citrus variety Hongmeiren as the female parent and the citrus varieties Ganping and cocktail grapefruit as the male parents,and the effect of gibberellin spraying period on the quality and fruit setting rate of citrus hybrid fruits was studied. The results showed that for the hybrid combination of Hongmeiren× Ganping and Hongmeiren × cocktail grapefruit,the fruit setting rate of pollination spraying treatment were 43.30% and 46.36%,respectively,which were significantly(p<0.05)higher than those of the control(21.20%,27.44%)and young fruit spraying treatments(23.93%,29.61%). The fruit solid-acid ratios of pollination spraying treatment of the two hybrid combinations were 26.17 and 26.21,while the fruit solid-acid ratios of young fruit spraying treatment were 23.35 and 24.40,which were significantly higher than those of the control(18.92,21.77). The results indicated that spraying 50 mg·L-1 gibberellin within 1-2 h after pollination could significantly improve the fruit setting rate and fruit quality of hybrid fruits,and showed the same promoting effect on the hybrid combination with large differences in pollen viability of male parents. The results showed that it was feasible to spray 50 mg·L-1 gibberellin within 1-2 h after pollination to improve the fruit setting percentage of hybrid fruits in the process of citrus cross breeding.
