摘要:
为研究玉米的耐盐机理以金帅2008、玉帅2008、河北邯郸585、晋中黑玉米种子为试验材料，分别用0、30、90、120、150、180 mmol·L-1 NaCl溶液处理，对玉米种子的发芽率、发芽势、发芽指数及其萌发过程中α淀粉酶的活性进行测定。结果表明：金帅2008、玉帅2008在NaCl浓度低于60 mmol·L-1、河北邯郸585在NaCl浓度低于30 mmol·L-1时，种子的萌发指标及α淀粉酶活性有一定升高，超过此浓度时萌发指标及α淀粉酶活性又逐渐降低；晋中黑玉米种子的萌发指标及α淀粉酶活性随着NaCl浓度的升高，而呈现下降趋势。
Abstract:
In order to study the salt tolerance mechanism of maize,the seeds of Jinshuai 2008,Yushuai 2008,Hebei Handan 585 and Jinzhong black maize were treated with 0,30,90,120,150 and 180 mmol·L1 NaCl solution respectively.The germination rate,germination potential,germination index and the activity of alphaamylase in the process of maize seed germination were determined.The results showed that when NaCl concentration was lower than 60 mmol·L1 in Jinshuai 2008 and Yushuai 2008,and when NaCl concentration was lower than 30 mmol·L1 in Hebei Handan 585 the germination index and alphaamylase activity of seeds increased to a certain extent,but when the above concentration was higher,the germination index and alphaamylase activity of seeds decreased gradually;and the germination index and alphaamylase activity of seeds of Jinzhong black maize decreased with increase of NaCl concentration.
