| 摘 要： | 目的]研究冬油菜体内必需金属元素在低温驯化过程中的变化特征,旨在揭示必需元素在油菜抗寒性中的作用及机理。方法]通过田间试验比较了不同抗寒性冬油菜(Brassic anapus L.)品种中双11号、甘油杂1号和金裕油1号体内必需金属元素(钙、镁、铁、锰、锌和铜)浓度在低温驯化过程中的变化。结果]油菜体内金属元素浓度在低温驯化过程中变化明显,且品种间差异显著。在根系中,钙、镁、铁、锰、锌和铜浓度均呈显著升高的趋势,可能与低温引起蒸腾作用降低从而导致向上运输受阻所致;在地上部,钙、镁、锌浓度显著降低,而铁、锰和铜为升高趋势,各元素浓度变化幅度均以中双11号最大。结论]维持地上部钙、镁、锌浓度稳定,提高地上部铁、锰、铜浓度,可能有利于冬油菜抗寒性的提高。

| Abstract: | Objective]The paper was to investigate the dynamics of essential metal elements(Ca,Mg,Fe,Mn,Zn and Cu)contents in winter oilseed rape(Brassica napus L.)during cold acclimation,and to reveal the effects and mechanisms of essential elements in cold resistance of oilseed rape.Method]Three varieties with different cold resistance including Zhongshuang No.11(ZS,freezing sensitive variety),Ganyouza No.1(GY)and Jinyuyou No.1(JYY,freezing tolerant varieties)were used in the study,and the changes of necessary meta... |
