摘　　要：对直干型和普通型大叶相思的种子品质和苗期质量的对比试验结果表明：直干型的种子品质优于普通型的；幼苗高、径生长量两者差异不显著；直干型苗期的死亡率较高，说明其抗逆能力较差。This experiment compared the seed and seedling qualities of straight bole type and common type of Acacia auriculiformis . The results showed that the quality of seeds from the straight type were better than those from common type; The growth of height and stem diameter of both type seedlings, however, were not significantly different. The higher seedling death rate of the straight type demonstrated its poorer hardiness. It is suggested that special attention should be paid to prevent the damping off of seedlings resulted from low temperature and high humidity.
