| 中文摘要: |
| 脆香甜柚是四川省南部县地方优良品种，但裂果严重，为找到既能有效防止脆香甜柚裂果又能保持其优良品质的方法。以沙田柚、江永香柚、琯溪蜜柚和本地酸柚花粉进行授粉处理，以不授粉为对照，研究了不同柚花粉授粉处理对脆香甜柚坐果率、裂果率和果实品质的影响。结果表明，与对照相比，琯溪蜜柚和沙田柚授粉处理的坐果率分别提高了17.0个百分点和14.3个百分点，差异均达显著水平。4个处理的裂果率均显著低于对照，其防裂效果为琯溪蜜柚>江永香柚>本地酸柚>沙田柚。4个处理均显著提高了脆香甜柚的产量，其中以琯溪蜜柚授粉的产量最高，为51.04kg，但各处理间差异不显著。在品质方面，4个处理均使脆香甜柚果实种子总数显著增加，但琯溪蜜柚授粉仅显著增加退化种子数。除江永香柚处理的可滴定酸含量显著高于对照、TSS/酸值显著低于对照外，其余处理的果实单果重、可食率、可溶性固形物含量、可滴定酸含量和固酸比与对照均没有显著差异。用琯溪蜜柚作为脆香甜柚的授粉树，既可防止裂果，又能增加产量和维持其优良品质。 |
| 英文摘要: |
| ‘Cuixiangtian’ pomelo [Citrus grandis(L.) Osbeck] is a local good citrus variety in Nanbu county in Sichuan province. However, it suffers severe fruit crack from July to October. This study aimed to find suitable pollination pomelo varieties for effective reducing ‘Cuixiangtian’ pomelo fruit crack with no or minimum side effects. ‘Cuixiangtianyu’ pomelo flowers were pollinated with the pollens of ‘Shatian’,‘Jiangyongxiang’,‘Guanximi’and local sour pomelos, respectively, and the fruit-set rate, fruit crack rate and fruit quality were measured. The results showed that the fruit-set rate of ‘Cuixiangtian’ pomelo was increased by 17.0% and 14.3% when pollinated with‘Guanximi’ and ‘Shatin’, respectively. All 4 pollination treatments had significantly reduced the fruit crack rates as compared with the control, and the fruit crack rate was ‘Guanximi’<‘Jiangyongxiang’ |
