本试验以从郑州刘庄种子市场购买的滑丰8号玉米种子为实验材料,配制了不同浓度的PEG-6000溶液(0,5%,10%,15%,20%)来模拟实验条件下不同的干旱胁迫条件,来探究不同干旱胁迫条件下对玉米种子萌发的影响。同时分别配制了不同浓度0(对照)、0.05、0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9、1.0 mol/L的NaCl 溶液,研究了不同浓度的NaCl 溶液对玉米种子萌发的影响。得出试验结论总结如下：随着试验中PEG-6000溶液浓度的增加,玉米种子萌发受抑制程度越大,玉米种子的发芽率,发芽势,胚根长度,胚芽长度,胚根/胚芽,发芽指数与PEG浓度的大小呈负相关；随着试验中NaCl溶液浓度的增加,玉米种子萌发受抑制程度越大,玉米种子的发芽率,发芽势,胚根长度,胚芽长度,胚根/胚芽,发芽指数随着的NaCl溶液浓度的增加而呈现出不同程度的下降趋势。

The corn seed, named‘Hua Feng 8st’,purchasing from seed market in Zhengzhou, Liuzhuang, was chose in this test. In order to explore ef ect of seed germination under different drought stress, the research was carried out by deploying different concentration of PEG-6000 solution (0,5%,10%,15%, 20%)and NaCl solution (0,0.05,0.1,0.2,...,1.0mol/L) to simulate different drought conditions in laboratory.The results showed that with the increase of concentration of PEG-6000 solution, the control ed extent of corn seed was bigger, and its germinationrate, germination power, germ length, radicel length and radicle/germ, negative correlation existed. As the concentration of NaCl solution went up ,these results also were fund in relevant indicators accordingly.
