15个澳洲坚果品种在云南的产量及品质

对云南4个澳洲坚果品比点的产量及品质数据分析结果表明:15个品种的产量及品质均低于澳大利亚和夏威夷等澳洲坚果主产区.在4个品比点中,15个品种6a的平均产量为2.24 kg/株,仅有H2、O.C、HAES900和广11的平均产量大于4 kg/株,接近澳大利亚良种标准.在品质指标的比较中,O.C、HAES900、H2、和广11好于其它品种.综合产量和品质分析.供试的15个澳洲坚果品种中,HAES900、O.C、H2、广11优于其它品种,但因广11果仁偏小,在云南热区可将HAES900、O.C和H2作为主导品种在生产上推广种植.

Yield and Nut Quality of 15 Macadamia(Macadamia spp.) Cultivars in Yunnan

A trial was established to compare 15 macadamia cultivars at 4 sites in Yunnan. Data analysis of yield and nut quality from these 4 sites showed that all the 15 cultivars had a lower yield and poor nut quality than those in the main macadamia producing areas, e.g. Australia and Hawaii. At the 4 comparison sites, 15 cultivars yielded 2.24 kg/tree/a over 6 years, of which only 4 cultivars (H2, O.C, HAES900 and Cuanll) yielded over 4 kg/tree/a, which is close to the yield of desirable cultivars in Australia. In terms of nut quality, cultivars O.C, HAES900, H2 and Guangll were better than others. In general, cultivars O.C, HAES900, H2 and Guangll among 15 cultivars were higher in yield and nut quality than the others, but the cultivar Guangll produced relative small kernel. Therefore, cultivars HAES900, O.C and H2 could be recommended as the main cultivars for commercial planting in Yunnan.
