| 中文摘要: |
| 以12年生兔眼蓝莓品种‘杰兔’为试材，研究了结果枝类型对着果率和果实品质的影响，在此基础上探讨了枝长和着果率与果实性状的相关性分析，以期阐明实现“着果率—单果重—产量—品质—效益”正相关关系的结果枝类型。研究结果表明，所试结果枝类型对着果率、叶果比、果实纵径、果实横泾、单果重和可溶性固形物(TSS)含量均有显著影响，长果枝和中果枝的终着果率为50%左右，显著高于短果枝和超长果枝，且平均果实数和TSS含量亦表现出相同的趋势。同时回归分析结果表明，TSS含量和预测平均枝产量最高的结果枝长度分别为33.38cm和45.64cm。综合分析表明，中果枝和长果枝是蓝莓实现优质高产的结果枝类型。 |

| In this study, it was investigated using the ‘Premier’ that the effects of different bearing shoots on fruit set and fruit quality in Rabbiteye Blueberry, so as to elucidate the correlation between fruit set and fruit quality and different bearing shoots. The results showed that there was a significant difference in fruit set, leaf-fruit ratio, longitudinal diameter, fruit diameter, single fruit weight and soluble solid content, among different bearing shoots. The final fruit set of long bearing shoots and middle bearing shoots was about 50%, which was significantly higher than extra-long bearing shoots and short bearing shoots. And the average number of fruit and TSS also showed the same trend. Meanwhile, the results of regression analysis showed that, the optimal length of bearing shoots were 33.38 cm and 45.64 cm for TSS and yield predicted per shoot respectively. In total, the aforementioned results showed that the long bearing shoots and middle bearing shoots are conducive to good quality and high yield in Rabbiteye blueberry. |
