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