| 摘 要： | 为研究干旱胁迫下小麦幼苗蛋白质和脯氨酸含量变化,进而探明不同品种小麦抗旱性差异,采用15％ PEG-6000渗透胁迫,检测20个小麦品种幼苗蛋白质和脯氨酸含量.结果表明,渗透胁迫下,不同品种小麦幼苗蛋白质含量对照组均高于15％ PEG处理组,品种间蛋白质含量变化率差异较大;不同品种小麦幼苗处理组脯氨酸含量均高于对照组,品种间脯氨酸含量变化率差异也较大;不同品种间处理组与对照组小麦幼苗蛋白质、脯氨酸含量差异均极显著;20个小麦品种中金麦8号、淮麦21和淮麦22具有较强的抗旱性.

| Abstract: | The seeding protein and proline content in 20 wheat varieties was studied under osmotic stress by 15％ PEG-6000,in order to find difference of different varieties and change of seeding protein and proline content under drought stress in wheat.The results showed that the seeding protein content in the control group showed increase compared with the treatment group and had significant difference on change rate among different varieties and that the seeding proline content in the treatment group showed increase compared with the control group and had significant difference on change rate yet.The seeding protein and proline content in different varieties had highly significant difference in the treatment group and the control group.The Jinmai 8,Huaimai 21 and Huaimai 22 had the higher drought resistance among 20 varieties. |
