| 摘 要： | 利用聚丙烯酰胺凝胶垂直板电泳法，研究了不同浓度ＮａＣｌ对冬小麦根（三叶期）过氧化物酶（ＰＯＤ）同工酶的影响，电泳结果显示：１ｍｇ／ｇ ＮａＣｌ胁迫电泳图谱Ａ区酶带较对照组增加２条，Ｂ区酶带增加１～３条；２ｍｇ／ｇ ＮａＣｌ胁迫时，Ａ区为１条酶带，Ｂ区酶带增加了３条；ｔ检验表明：１ｍｇ／ｇ ＮａＣｌ胁迫时Ｂ区新增３条酶带的品种的株高和穗长极显著（Ｐ〈０．０１）高于Ｂ区新增１条酶带的品种。

| Abstract: | Effects of salt stress with different concertrations on POD isoenzyme of winter wheat roots in three leaf stage were studied by PAGE.The results showed:in the case of 1 mg/g NaCl,the isoenzyme bands were two more than control in region A,and 1-3 more than control in region B,the stem height and spike length of varieties with three new bands were higher than that of those with one new band in region B.In the case of 2 mg/g NaCl,comparing with control,the number of isoenzymes bands was no difference in region A,but three new bands appeared in region B. |
