摘　　要：采用旱棚盆栽研究土壤水分胁迫对白菜型油菜根系发育、根系活力、组织水状态和根冠比的影响。结果表明,土壤水分胁迫能促使白菜型油菜的根幅、主根长度、未级支根系、根系活力等的增加,杂交种增加幅度大于常规品种。开花期和成熟期抗旱性强的品种BWC/HWC值和根冠相比较大。The root growth, root tissue water status and root/cap of campestric were investigated under oil water stress increased. The result showed that root extension, main root length, terminal branch root and root vigor were increased under soil water stress, and variety with drought resistance possessed high BWC/FWC and root/cap in flowering stage and maturity stage.
