| 摘 要： | 研究了体积分数为0.2%、0.4%、0.6%、0.8%、1.0%、1.2%、1.4%、1.6%、1.8%的NaCl溶液对黑麦种子抗盐性的影响。结果表明,在盐胁迫下,随NaCl的增加,黑麦的发芽率逐渐下降,平均发芽时间随NaCl的增加而变长。胚芽和胚根长度随NaCl的增加受抑制程度增加,根数随NaCl的增加呈现递减的现象。

| Abstract: | Under the concentration of 0.2%,0.4%,0.6%,0.8%,1.0%,1.2%,1.4%,1.6% and 1.8% of NaCl solution,anti-salinity experiment of secale cereale seeds was carried out.The result indicated that under salt stress,germination percentage,germination index and vitality index of secale cereale gradually dropped,and average germination time prolonged along with increase of salinity concentration.In addition,the length of plumule and radicle and the number of roots were suppressed along with increase of salinity concentration. |
