红皮云杉种源间及家系间苗期高生长变异性研究

对红皮云杉5个种源(2年生)苗高生长分析结果表明,红皮云杉种源间存在丰富的变异,变异系数在25.6%~31.2%之间,平均值为28.28%;5个种源间苗高生长差异极显著,高生长最大的鸡西种源(11.5 cm)与克什克腾种源(11.3 cm)分别高出生长量最小的塔河种源(9.05 cm)27.07%和24.86%。各种源内家系之间存在丰富变异,其中克什克腾种源家系间变异最大,变异系数在22.1%~35.3%之间,平均值为27.53%,高生长最大的C15号家系高出最小的C12号家系62.4%,种源内家系间苗高差异极显著。

Report of the Variation on Seedling Height Growth of Picea koraiensis in Provenances and Families

The height growth of two-year-old Picea koraiensis that concluded 5 provenances were analyzed.The result showed that there were rich variations among provenances and the variation parameter fluctuates from 25.6% to 31.2%,and the average is 28.28%.The differences of seedling height growth among five provenances reach the extreme marked level.The height growth of Jixi provenance(11.5cm)and Keshiketeng provenance(11.3cm)were the greatest and which exceed Tahe provenance(9.05cm),the lowest provenance,27.07% and 24.86% respectively.There were significant variance among families for each provenance,and the variation parameter among the Keshiketeng provenance families was the largest range which from 22.1% to 35.3% and the average level was 27.53%.Among the Keshiketeng families,C15 and C12 was the highest and lowest respectively,and the former exceed the later 62.4%.The result showed that there was significant variance in seeding height growth among families for each provenance.
