摘　　要：用硅胶干燥处理豇豆种子,将种子含水量降到4.4%或3.1%(湿基),在20℃温度条件下密封贮存8年后,二者具有与对照(含水量7.7%,0℃)种子相似的贮存效应,显示其在常温下良好的耐藏性。但含水量3.1%处理的种子贮存至10年时,种子活力下降显著。Cowpea seeds were treated with silica gel and its water content was reduced to 4.4% or 3.1% . Its storage effect is the same as stored under 0 ℃ with 7.7% water content after the sealed seeds were stored for 8 years under 20℃ . However, after the seeds with 3.1% water were stored for 10 years its vigor descended significantly .
