本试验对我国首批选出的枫香优树 83个子代进行了苗期测定 ,其结果表明 :优树子代平均场圃发芽率 35 .6% ,最高家系达 5 7.0 % ,最低家系仅 12 .3% ,家系间差异极显著 ;保存率主要受场圃发芽率影响 ,差异不甚明显。家系间苗高生长量差异极显著 ,有 15个家系显著优于对照 ,占参试家系数的 18.3%”
In this study, 83 progenies of Liquidambar formosana were selected for seedling determination. The results showed that the average seed germination rate was 35.6%, the highest pedigree reached 7.0%, the lowest pedigree only 12.3%. There was a significant difference among pedigrees. The rate of preservation was mainly affected by the germination rate of field nursery, but the difference was not obvious. There was a significant difference in the growth of seedling height between families, 15 families were significantly better than the control, accounting for 18.3% of the coefficient of the test "
