摘　　要：对山东枣庄抱犊崮林场37个地理种源的23年生侧柏种源林种子的发芽率、发芽势、活力指数、发芽值4个指标研究发现:不同地理种源间侧柏种子的发芽能力存在很大差异,福建南平(FNP)、辽宁凌源(LLY)、甘肃徽县(GHX)3个种源发芽能力较强,发芽率分别为65.00%,62.50%和52.00%;山东灵岩(SLY)、河南灵宝(HLB)、内蒙乌拉山(NWS)发芽能力较弱,发芽率仅为6.50%,7.50%和10.50%。确定枣庄抱犊崮林场及毗邻地区种子发芽能力最佳种源为福建南平(FNP)、辽宁凌源(LLY)、甘肃徽县(GHX)3个种源。A seed test on 23-year-old experimental plantation with 37 geographical provenances of Platycladus orientalis on Baodugu Forest Farm in Zaozhuang, Shandong Province was conducted by taking germination percentage, germination potential, vigor index and germination value as test indices. The results showed that there were significant differences in the germination ability of P. orientalis seed among the provenances. The germination abili- ty of Fujian Nanping provenance （ FNP）, Liaoning Lingyuan provenance （LLY） and Gansu Huixian provenance （GHX） was stronger and the germination rate was 65.00%, 62.50% and 52.00% , respectively. The germination ability of Shandong Lingyan provenance （SLY） , Henan Lingbao provenance （ HLB）, Neimeng Wulashan provenance （NWS） was weaker, and the germination rate was only 6.50% , 7.50% and 10.50% , respectively. The provenances from Fujian Nanping （FNP）, Liaoning Lingyuan（LLY） and Gansu Huixian （GHX） were identified as the best for the Baodugu Forest Farm and the adjacent areas in Shandong Province according to the seed germination ability indexes.
