摘　　要：以3年生澳洲坚果品种‘A16’半同胞家系的155株化学诱变苗为材料,进行茎粗生长量的变异分析,结果表明:(1)澳洲坚果诱变苗木的茎粗生长量受遗传因素和秋水仙素共同影响,产生了丰富的变异,处理间变异系数排序为处理E(39.37%)>处理A(38.9%)>处理F(29.54%)>处理B(26.22%)>处理D(21.25%)>处理C(16.68%)>对照(14.58%);(2)对照(CK)苗木长势比较整齐,化学诱变苗木受秋水仙素影响,苗木长势参差不一,同一处理内茎粗的最大值是最小值的5.38倍;(3)对照(CK)的年均增粗量最快为14.72 mm,处理F增粗最慢年均增粗8.82 mm。3-year-old of seedlings by chemical induction from half-sib progenies family of macadamia ‘ A16’ were used as materials,and the variation of basal diameter was analyzed. The results showed that the seedlings of chemical induction had highvariation under the influence of both gene and colchicines. Variation coefficients in different treatments ranked as following：Treatment E（39.37%）〉Treatment A（38.9%）〉Treatment F（29.54%）〉Treatment B（26.22%）〉Treatment D（21.25%）〉Treatment C（16.68%）〉Control（14.58%）. Seedlings in control showed relatively orderly while that of chemical inductionshowed uneven. The maximum value of diameter was 5.38 times than the minimum one under the same treatment. The fastestenlargement for diameter averaged in 14.72 mm annually in control, and the slowest enlargement was only 8.82 mm in treatmentE. This high variation will then provide a theoretical foundation for chemical induction of macadamia.
