| 摘 要： | 在广东省八一林场试验点，对来自全国11个种子园组的110个杉木优良家系的苗高生长节律进行了研究.结果表明种子园组间，7月初以前存在显著差异，以后差异不显著；家系间从6月1日起始终存在极显著差异；与对照比较，91.82%的家系优于对照，经LSD法检验，有39.02%和26.33%的家系分别达较显著和显著水平；9.09%达极显著水平；1年生苗高生长在生长的前期与后期，存在极显著相关性，10月中下旬起，秩次相关系数高且趋于稳定，达0.862～0.912.

| Abstract: | This paper deals with the height growth rhythm of 110 elite families from 11 groups of Cunninghamia lanceolata orchards in China. The experiment site is Bayi State own Forest Farm. The results show that the growth before early July is eminently different among orchards groups, but after July it has no eminent difference; that the growth of elite families after June 1st always eminently different; and that 91.82% of families grow faster than the control does. The results of LSD show that the growth of 39.02% families is relatively higher than that of the control and the growth of 26.33% families is obviously higher than that of the control; and that there is an early late relationship of seedling growth and after October the relationship is stable with a coefficient between 0.862 to 0.912 . |
