为突破澳洲坚果存在嫁接难且成活率低等育苗技术难题,研究以华南地区 8 个常见澳洲坚果
品种为砧木和 4 个品种为接穗,采用层次分析法赋值比较砧木—接穗成活率、新梢分支数、最健壮的新
梢直径、新梢最长长度以及新梢氮、磷、钾含量等 7 个指标,结果表明 8 种澳洲坚果砧木品种从优到劣
的顺序为 695 > 900 >桂热 1 号> H2 > A16 > OC >南亚 3 号> 788,亦发现了 3 个最佳砧木 - 接穗的
搭配为 695-A16、900- 桂热 1 号和桂热 1 号 -A16。砧木和穗条的合理选择是解决澳洲坚果嫁接技术难题
的关键。 |

Abstract: |
To resolve the technical problems of difficult grafting and low survival rates in Macadamia spp.,
in this study, eight common varieties of Macadamia spp in South China were used as stocks, and four varieties
were used as scions. An analytic hierarchy method was applied to compare seven indexes including survival
rates of different scions, numbers of newly sprouted shoots, diameters of the strongest new shoots, and content of
nitrogen, phosphorus, and potassium in the new shoots. Our results show that eight stocks of Macadamia varieties
were ordered from the best to the worst: 695>900>Guire No.1>H2>A16>OC>Nanya No.3>788. The top three
stock-scion combinations were 695-A16, 900-Guire No.1 and Guire No.1-A16. Selection of suitable stocks and
corresponding scions is essential to resolve the problems of the grafting techniques in Macadamia spp.. |
