| 摘要: |
| 为了了解冬油菜苗期抗寒性与抗旱性的相关性，为北方旱寒区抗寒、耐旱冬油菜新品种选育提供理论参考，本试验对抗寒性不同的8个白菜型冬油菜品种进行苗期抗旱胁迫研究。结果表明，冬油菜抗寒性与抗旱性显著正相关；干旱胁迫后，油菜叶绿素含量逐渐增加，组织含水量与抗旱性不存在相关性，根系活力与抗旱性存在极显著相关性。 |

| Abstract: |
| To investigate the correlation between cold resistance and drought tolerance of winter rapeseed and provide new materials to rapeseed improvement for cold resistant and drought tolerant, the paper studied the drought tolerance of winter rape from eight cold resistance types. The results showed that cold resistance and drought tolerance were significantly correlated. Root vigor and leaf chlorophyll of winter rape were highly correlated with drought tolerance, while tissue water content was not correlated with it. |
