| 摘 要： | 亚稳定可塑性会显著影响植物个体的适合度和个体对环境的反应模式,因此,探讨其起因和维持机制成为非常重要的科学问题.喜旱莲子草性别特征表现为亚稳定可塑性而其它表型特征为常规的可塑性.通过正交控制实验,量化喜旱莲子草的表型特征在不同环境条件下的可塑性表现.结果表明:(1)决定喜旱莲子草性别可塑性和其他大多数可塑性的环境因素相...

| Abstract: | Metastability plasticity could significantly affect the fitness and response model of individual plant to environment.Therefore,it is important to explore the inducement and operating mechanism of metastability plasticity.Alternanthera philoxeroides shows metastable plasticity on gender trait,but stable plasticity on other phenotypic variations.In this study,orthogonal experiments were conducted to quantify the plasticity of phenotypic traits on A.philoxeroides,under various control conditions.The result sh... |
