| 摘 要： | 目的]为蓝桉种子的常温贮藏提供理论依据。方法]以干燥处理后含水率分别为9％、8％、7％、6％、5％、4％、3％、2％、1％并在常温条件下密封贮藏300、54．0d及未经干燥处理分别在常温和低温条件下贮藏300、540d（对照）的蓝桉种子为材料，测定不同处理种子的发芽、幼苗生长及生理生化指标。结果]超干燥处理的蓝桉种子（含水率9％～1％）常温密封贮藏300、540d后，种子发芽率、发芽势、细胞膜透性、脱氢酶活性、α-淀粉酶活性总体高于常温对照组而接近低温对照组，部分指标甚至高于低温对照组；当种子含水率为2％时，种子的发芽能力、幼苗生长及生理生化特性最好。结论]蓝桉种子超干燥处理后长期常温贮藏是完全可行的，且种子最佳含水率为2％．
