摘　　要：为明确湿度和NaCl浓度对花生种子活力及发芽的影响,开展了发芽床不同含水量及NaCl浓度对铜仁珍珠豆型花生种子活力及发芽的影响研究。结果表明,发芽床含水量从20%升高至40%,铜仁珍珠豆型花生种子的发芽率、发芽势、发芽指数呈上升趋势;含水量继续升高至60%,3项指标均呈下降趋势,40%是铜仁珍珠豆型花生最适发芽床含水量,花生发芽各项指标达到最高。用NaCl溶液处理种子,浓度从0 mol/L升高至0.5 mol/L,花生种子的发芽率、发芽势、发芽指数这3项指标表现出先急剧下降后缓慢下降又急剧下降的趋势。In order to clarify the effects of humidity and NaCl concentration on seed vigor and germination of peanuts,this paper studied the effects of germination bed with different water contents and concentrations of NaCl on seed vigor and germination of Tongren pearl bean type peanuts.The results showed that the seed germination rate,germination potential,germination index of peanuts increased when the germination bed water content increased from 20%to 40%,then all three indicators decreased when the germination bed water content reached 60%.The optimum water content of germination bed for Tongren pearl bean type peanuts was 40%,the indicators of peanut sprout was the highest.When the seeds were treated with NaCl solution(from 0 mol/L to 0.5 mol/L),the germination rate,germination potential and germination index of peanut seeds showed a trend of sharp-gentle-sharp decline.
