【摘要】 以吉林省露水河林业局宏伟种子园收集的红松全分布区的优树无性系为材料,对其结实性状进行观测与综合分析,结果表明:在628个无性系中,选择出红松结实性状特别优良的无性系11个,优良无性系51个,共计62个。为今后建设红松种子园和果林基地提供了实践依据与基因储备。更多还原

【Abstract】 The fructification character of the plus tree clone of Pinus koraiensis distribution area which was selected by Hongwei seed orchard of Lushuihe Forestry Bureau of Jilin Province was observed and analyzed synthetically. The result showed that 11 particularly superior clone and 51 superior clone of fructification character of Pinus koraiensis were selected from 628 clones. The total number was 62. It provided practical basis and gene reserve for constructing the seed orchard of Pinus koraiensis and fruit forest base.更多还原
