摘要
【目的】分析菠萝对云南幼龄橡胶林下的气候适应性,筛选出适合幼龄橡胶林下间作的菠萝品种。【方法】在橡胶林下采用随机区组设计,对8号、冬蜜、金菠萝和蜜宝等4个品种进行引种试种试验,收获前观察生育期,收获后测定果实产量与品质。【结果】在云南幼龄橡胶林下,8号自然抽蕾率达29.84%,显著高于其他3个品种;金菠萝的单果重最重,为1057.50g;8号、冬蜜、金菠萝和蜜宝的果形指数分别为1.33、1.13、1.13、1.11,8号相对较好;8号、冬蜜、金菠萝和蜜宝果心宽为1.43、1.82、2.08和1.56cm,金菠萝的果心最宽,与8号、蜜宝差异显著;可溶性总糖含量8号最高达12.97%;果实内在品质综合评价8号最好,其次为金菠萝、蜜宝、冬蜜。【结论】8号、金菠萝和蜜宝可作为鲜食品种在云南地区推广种植。
[Objective]Climate adaptability of pineapple was assayed to screen out the pineapple varieties suitable for in- tercropping in young rubber plantation. [Method]Randomdized block design was applied in introduction tests of pineapple cul- tivars No.8, Dongmi, Golden pineapple and Mibao. Growth duration was observed before harvest and fruit yield and quality were measured after harvest. [Result]After intercropping with young rubber plantation in Yunnan province, the tested four cuhivars displayed good growth adaptability and fruiting habits. The bud rate of No.8 was 29.84%, which was remarkably higher than that of the other three cultivars. The fruit shape indexes of No.8, Dongmi, Golden pineapple and Mibao were 1.33,1.13, 1.13 and 1.11, respectively, which indicated that No.8 had the best fruit shape. The core widthes of No.8, Dongmi, Golden pineapple and Mibao were 1A3, 1.82, 2.08 and 1.56 cm,respectively, in which core width of Golden pineapple was the biggest and significant different from that of No.8 and Mibao. Total soluble sugar content was in order of No.8 （12.97%） 〉Golden pineapple （10.54%） 〉 Dongmi （10.23%）〉 Mibao （9.84%）. [Conclusion]No.8,Golden pineapple and Mibao could be extended in Yunnan province as fresh fruit species.
