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.

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.
