Character performance and evaluation of Bellamy navel orange and Fukumoto navel orange in Guangxi Province_ | Bellamy和福本脐橙在广西的性状表现及其评价

Chinese. ［目的］研究Bellamy和福本脐橙在广西的性状表现。［方法］研究了Bellamy和福本脐橙在桂林的物候期、植物学特性、结果性能、果实性状、适应性与抗性，并作出了综合评价。［结果］Bellamy和福本脐橙均表现生长快、结果早，较抗旱。其中，Bellamy脐橙树势稍弱，树形开张，树冠扁圆头形，脐黄落果率为19.42%~39.46%，裂果率为3.18%~7.85%，4~5年生株产量为9.00~12.62 kg，果实11月中下旬~12月上旬成熟，单果重为149.40~179.25 g，固形物含量为10.2%~15.2%，甜酸适中，化渣，表现为早熟、高产、优质、脐黄中等、裂果少；福本脐橙树势稍旺、树形稍开张，脐黄落果率为8.21%~33.88%，裂果率为2.79%~14.7%，4~5年生株产量为7.83~24.63 kg，果实11月上中旬~12月上旬成熟，单果重为225.05~286.40 g，固形物含量为11.0%~13.4%，甜酸适中，化渣，表现为早熟、高产、优质，脐黄、裂果较少。［结论］ 2个品种均值得推广。_

English. ［Objective］ The aim was to study the character performance of Bellamy navel orange and Fukumoto navel orange in Guangxi Province. ［Method］ The phenophase, botanical characteristics, fruiting ability, fruit characters, adaptability and resistance of Bellamy navel orange and Fukumoto navel orange in Guilin were studied and evaluated. ［Result］ Bellamy navel orange and Fukumoto navel orange both presented as rapid growth, early bearing and better drought_resistance. Among them, Bellamy navel orange had relatively weak tree vigor, open tree shape and oblate crown. Meanwhile, its dropped fruit rate of navel yellow was 19.42%-39.46%; its cracking fruit rate was 3.18%-7.85%; its single output of 4-5 years old plants was 9.00-12.62 kg; its fruit matured from the middle and last ten days of November to the early ten days of December, and its single fruit weight was 149.40-179.25 g; its soluble solid content was 10.2%-15.2%; its sweet and sour were moderate; and it presented as early maturity, high yield, high quality, middle navel yellow and few cracking fruit. Fukumoto navel orange had relatively strong tree vigor and slightly open tree shape; Meanwhile, its dropped fruit rate of navel yellow was 8.21%-33.88%; ts cracking fruit rate was 2.79%-14.7%; its single output of 4-5 years old plants was 7.83-24.63 kg; its fruit matured from the early and middle ten days of November to the early ten days of December, and its single fruit weight was 225.05-286.40 g; its soluble solid content was 11.0%-13.4%; its sweet and sour were moderate; and it presented as early maturity, high yield, high quality, few navel yellow and cracking fruit. ［Conclusion］ The 2 varieties were both worth popularizing._
