摘要
雌雄异株植物通常表现出性二态性，在形态、生理和生命史特征方面存在差异。以前的研究大多集中于繁殖期间或繁殖后雌雄个体的差异，很少关注个体的繁殖前阶段。在这里，我们评估了雌雄异株植物 Silene latifolia 的雌雄个体在不同生命阶段对非生物胁迫的反应，包括生殖前（即幼苗和幼株）和生殖个体。我们测量了在养分缺乏、水胁迫及其相互作用下的生长、资源分配和对 13C 的鉴别。我们观察到根系生长的性双态性，雌性幼苗的主根比雄性植株长。生殖前的雌雄植株在根系分配方面对养分和水分供应的反应也不同。在繁殖期，当水分不受限制时，雌株比雄株长出更多的根。这些差异有助于解释在 S. latifolia 的自然种群中发现的雌偏性别比例。虽然在幼苗阶段雌性的叶片比雄性长，但我们没有发现地上部干质量存在性二态性的证据。我们的结论是，花叶榕的性别二形性可能不是繁殖的结果，而是早在繁殖之前就出现了。
期刊介绍：
Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology.
Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
