Bellamy和福本脐橙在广西的性状表现及其评价

Character Performance and Evaluation of Bellamy Navel Orange and Fukumoto Navel Orange in Guangxi Province

[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9．00～12．62kg，果实11月中下旬～12月上旬成熟，单果重为149．40～179．25g，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7．83～24．63kg，果实11月上中旬～12月上旬成熟，单果重为225．05～286．40g，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。

[ Objective ] Tile 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.
