摘要

全球不断变化的气候条件正在增加世界一些地区的干旱发生率。据预测,干旱不仅会影响植物的生长和花朵的发育,还会影响植物与授粉者之间的相互作用以及嗜昆虫植物的授粉成功率。然而,我们对干旱如何影响有性多态物种的不同花朵以及花朵间花粉传递的认识还存在很大差距。在这里,我们评估了雌雄同株的斯蒂文油南瓜,并分别评估了雌花和雄花在干旱胁迫下对花朵产量、花瓣大小、花蜜、花香和熊蜂授粉者造访的反应。除花香外,干旱胁迫对所研究的所有花卉性状都产生了不利影响。虽然雌雄花都受到干旱胁迫的不利影响,但雌花受到的影响更为严重,大多数雌花甚至在开放前就已经凋谢。干旱对传粉昆虫的访花也有负面影响,传粉昆虫通常更喜欢雌花。总之,我们的研究强调了一种雌雄同株植物的两性花受干旱胁迫的影响是不同的,因此需要进一步研究,以更好地了解传粉昆虫用来区分雄花和干旱胁迫植物花朵的线索。

期刊介绍: New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
