香蕉不同品种生长发育、结果性状和产量比较

为了评价不同香蕉品种在广西的表现，对广西崇左市龙州县 10 月秋植的 6 个香蕉品种（桂蕉 6 号、中蕉3 号、中蕉 4 号、中蕉 6 号、巴西蕉、南天黄）的生长发育、结果性状和产量进行了比较，旨在为广西香蕉生产的品种结构调整提供理论依据。试验结果表明：在整个生长发育阶段的同一时期，生长最旺的是中蕉 3 号，最弱的是南天黄，中等的是桂蕉 6 号、中蕉 4 号、中蕉 6 号和巴西蕉。生育期最长的是桂蕉 6 号和巴西蕉，比生育期最短的中蕉 3 号和中蕉 4 号多 17.8 d，南天黄和中蕉 4 号居中。产量最高的是桂蕉 6 号、中蕉 3 号、中蕉 4 号和中蕉 6 号，但 4 个品种间产量没有显著差异，其次是巴西蕉，最低是南天黄。果实综合性状较好的是中蕉 4 号、桂蕉 6 号、中蕉 3 号和中蕉 6 号，南天黄和巴西蕉较差。从综合表现看，中蕉 3 号、桂蕉 6 号、中蕉 4 号和中蕉6 号表现较好，适合在广西种植并获得较高产量，南天黄和巴西蕉表现较差。香蕉不同品种的假茎高度、假茎和叶片数的月增长量与月积温均呈显著或极显著相关关系，在一定温度范围内，高温促进香蕉植株的生长，低温则抑制香蕉植株的生长。

Comparison of Growth,Fruit Setting Characters and Yield of Different Banana Varieties

In order to evaluate the performance of different banana varieties planted in Guangxi, the growth, fruit set?ting and yield characters of six banana varieties (Guijjiao No. 6, Zhongjiao No. 3, Zhongjiao No. 4, Zhongjiao No. 6, Brazil Banana and Nantianhuang) planted in early September in Longzhou County, Chongzuo City, Guangxi were com?pared. It could provide a theoretical basis for the variety structural adjustment of banana in Guangxi. The results showed as follows: During the same development period, the growth of Zhongjiao No. 3 was the most prosperous. The weakest one was Nantianhuang, the medium were Guigui No. 6, Zhongcao No. 4, Zhongjiao No. 6 and Brazilian banana. The growing period of Guijiaoo No. 6 and Brazilian bananas was the longest, which was 17.8 days longer than that of Zhongjiao No. 3, and Zhongjiao No. 4 with the shortest growing period, and that of Nantianhuang and Zhongjiao No. 4 was in the middle. The yield of Guijiao No. 6, Zhongjiao No. 3, Zhongjiao No. 4 and Zhongjiao No. 6, with no signifi?cant difference among them were the highest, and the lowest was Nantianhuang. The synthetic fruit traits of ZhongjiaoNo. 4, Guijiaoo No. 6, Zhongjiao No. 3 and Zhongjiao No. 6 were better than that of the others. Judging from the com-prehensive trait performance, Zhongjiao 3, Guijiaoo 6, Zhongcao 4 and Zhongcao 6 performed well, which were suitable for planting in Guangxi. The monthly growth of pseudostem height, pseudostem circumstance, and leaf number of different banana varieties showed significant or extremely significant correlation with the monthly accumulated temperature. In a certain temperature range, high temperature promoted the growth of banana plants, and low temperature suppressed banana plants.
