摘　　要：通过控制超干处理时间获得8.09%、4.12%、2.03%3种不同含水量的籽粒苋(Amaranthus hypo-chondriacus)种子,在50℃恒温箱内进行人工老化处理10 d,回水后测量种子发芽率等指标。结果显示,老化前超干种子与未超干种子各项指标无明显差异,老化后4.12%超干处理的籽粒苋种子发芽率、脱氢酶和过氧化物酶均高于对照组,电导率、丙二醛含量低于对照组,并且抗老化效果优于2.03%超干处理,表明适度含水量的超干处理可以使籽粒苋种子保持较高的活力,提高其耐贮藏性。An experiment was conducted to determine the effects of ultra drying on vigor of Amaranthus hypochondriacus seeds.The seeds of A.hypochondriacus were ultra dried at different time to get seeds with 8.09%,4.12% and 2.03% of moisture content,respectively.These seeds were stored in calorstat at 50 ℃ temperature for 10 days to age.The germination rate and other physiological parameters of aged seeds and no-aged seeds of A.hypochondriacus were measured in this study.The results of this study showed that there we...
