摘要
通过对清河城红松无性系种子园优树收集区内550个无性系2 196株母树连续4年进行结实情况及生长性状观测调查,结果表明:清河城红松林木种子园各无性系间结实量差异极显著;采取显现概率法选育出179、332、380、589、578、328等43个高产结实无性系,平均结实量增产114%。
Observation survey(yield and growth characteristics)was conducted on 2 196 mother trees of 550 clones in Qinghecheng Pinus koraiensis Seed Orchard for four years.Result shows that:seed yield among clones of Qinghecheng Pinus koraiensis Seed Orchard are significantly different;43high-yielding clones(P.koraiensis 179,P.koraiensis 332,P.koraiensis 380,P.koraiensis 589,P.koraiensis 578 &P.koraiensis 328 and others)were selected by adopting apparent probability method;the mean seed yield increase by 114%.
