| 摘 要： | 采用不同剂量（3000、5000、7000Rad）(60)Co－r辐照肯氏相思种子，选育出诱变化株（M1），以M1的种子（M2）扩种试验。观测M1和M2代的形态、物候，并测定过氧化物酶同功酶带谱、酶活性、蛋白质含量，结果表明，各处理的优株与对照都存在差异。在相同生态条件下，M1代林木生长量和民代地上部生物量分别高于对照见11.48％～21．64％和14．62％～73．98％，以5000Rad辐照剂量最优，其次为7000Rad。访变个体后代表现树干直、花果期提早和种子小。

| Abstract: | M1 mutant was selected from the seeds of Acacia cunninghamia by (60)Co-r irradiation. The results of afforested experiment by using M2 mutant showed that the growth and biomass of 3-year stands increased by 21. 64% and 73. 98%, respectively as compared with controls, and the stands had straight stems and earlier flower phase and fruit maturity period for 7-15 days. |
