传粉昆虫对棕榈海葵黄色紫外线花纹与白色无紫外线花纹花朵二形性的反应。
花色多态性在被子植物中并不常见,但却很普遍,可以通过各种平衡选择机制来维持。棕榈海葵大多为黄花,但在一些种群中也有白花植株。我们分析了棕榈海葵在其分布区内的颜色形态分布。我们还分析了它们的颜色特征,并比较了它们的无性和有性生殖特征、授粉者关注度和适应性。棕榈属植物的分布范围仅限于西地中海地区,而白花植物则仅限于葡萄牙和西班牙西南部,在这两个地区的白花植物比例较低。黄花具有独特的紫外线模式,中心吸收紫外线,外围反射紫外线,而白花则没有这种模式。两种形态的颜色特征非常明显,便于传粉者区分。两种形态均为原雌花,有性阶段的持续时间相同,除花色外,与吸引传粉昆虫有关的主要花朵特征也相似。膜翅目昆虫和双翅目昆虫是主要的传粉昆虫,表现出对黄色形态的偏好,传粉昆虫群在两种颜色形态之间有明显的分工,并且在觅食过程中对花朵颜色有明显的恒定性。两种形态都结合了克隆繁殖和有性生殖,但白花植物的有性生殖潜力较低。最后,黄色形态的雌性适合度较高。尽管白花植物的受粉率和适应性较低,但传粉者分工和花色恒定性可以维持这种多态性,从而促进其克隆繁殖。

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.

Permeability of postzygotic barriers: embryology of a partially fertile Epidendrum (Orchidaceae) hybrid. Issue Information Modulatory responses of physiological and biochemical status are related to drought tolerance levels in peanut cultivars. Reduced soil moisture drives leaf anatomical shifts more than chronically elevated temperatures in European temperate trees. Salicylic acid priming before cadmium exposure increases wheat growth but does not uniformly reverse cadmium effects on membrane glycerolipids.
