| 摘 要： | 对9个不同产地的大青杨进行了苗期生长量测定,经方差分析,地径与苗高生长量均呈显著差异,3年间的地径、苗高间的净生长并不呈相关关系。经遗传力估算,试验点的优劣对大青杨第1年生长有较大影响,第2、3年生长遗传性非常稳定。通过本试验为东北各造林区选用适用种源提供了依据。

| Abstract: | The growth yields of Pinus ussuriensis Kom.during seedling stage have been measured from 9 different habitat.After variance analysis,there is obvious difference between diameter and height,but there is no correlated relation between the net increment of height and diameter in 3 years.Through the estimate of heritability,the condition of experimental plot can obviously influence growth in first year,the heritability of growth in second and third year is very stable.This experiment can provide the basis for choosing suitable provenances in forestation area in Northeast. |
