近两年,我们在河南省郏县林场三个地点开展了侧柏全分布区种源造林试验和种源与家系两个水平的造林试验,对侧柏种源间以及种源内家系间造林成活率的变异进行分析,为选择优良种源提供依据。一、材料与方法供试种源51个;种源与家系两个水平造林试验供试种源11个。每个种源含家系11～
In the past two years, we conducted afforestation experiments with provenances and family provenances in three sites of Juxian Forest Farm in Henan Province. The afforestation experiment was conducted between Arborvitae and their provenance families Rate of variation analysis, to provide a good basis for selection of provenances. First, materials and methods for the test source 51; provenance and family two horizontal afforestation test for the test provenance 11. Each provenance contains pedigree 11 ~
