结果表明，玉米种子的发芽势、发芽率、发芽指数和活力指数均随老化时间的延长而降低；
Activity of POD, which was positively correlated with virous vigor indexes of maize seeds, was also declined with aging time.
随着盐处理浓度增高，发芽率和发芽势呈下降趋势，胚芽、胚根的生长也受到抑制，但也有例外。
The germination potential and rate of germination are declined, the growth of embryo and radicle are inhibited with salt concentration increasing, though with some exception.
但不同的玉米品种在抗旱性上存在极显著差异，抗旱性强的品种在水分胁迫下仍然保持较高的发芽势和发芽率。
There were obvious difference on drought resistance among the varieties, higher drought resistance varieties kept higher vigor of germination and germination (capacity).
