, a dioecious shrub willow, has been widely used in phytoremediation, yet sexually differences in tolerance to cadmium of which remained unclear. This study focused on different responses to cadmium stress between roots of male and female . Results show that male plants of have stronger cadmium tolerance than female plants, which indicates male should be more considered to be applied for phytoremediation and ecological restoration of cadmium-accumulated soil considering cadmium tolerance characteristics. The findings can provide valuable evidence and insights for researches focused on phytoremediation with dioecious woody plants and sexual dimorphism under abiotic stress.
性别二态的灌木柳，被广泛应用于植物修复领域，然而其对于镉胁迫的耐受存在性别差异，这一差异的具体情况尚不清楚。本研究主要关注了镉胁迫下，雌雄柳树根之间的不同响应。结果表明，雄性植株比雌性植株具有更强的镉耐受能力，这表明考虑到镉耐受特性，在应用于镉污染土壤的植物修复和生态恢复时，雄性柳树应该得到更多的重视。该研究结果可为利用雌雄异株木本植物进行植物修复以及非生物胁迫下的性别二态性研究提供有价值的证据和见解。
