取玉米4个类型代表品种进行人工老化试验的结果表明,随着老化天数的增加,发芽率、发芽指数、活力指数均呈下降趋势,糯质型下降慢,其次是粉质型,以硬粒型最快,初步认为糯质型及粉质型耐藏性优于硬粒型及马齿型。对种子活力进行评价时,活力指数是一个比较灵敏的指标。
The results of artificial aging test showed that the germination rate, germination index and vigor index decreased with the increase of aging days, the waxy type decreased slowly, followed by the silty type, Type the fastest, initially that waxy and silty-type storage better than the hard-type and the dent. When evaluating seed vigor, the vitality index is a more sensitive indicator.
