创新的多尺度方法研究四种苋属植物幼苗叶片表型变异。
通过图像分析(从显微镜图像到通过遥感进行的大规模采集)对植物形态解剖性状进行表型分析,是一种低侵入性的工具,可以深入了解生理和结构性状的变化,以及植物与环境的相互作用。苋菜属植物表型多样性高,包括对重要夏季作物和营养粮食或蔬菜作物具有高入侵性和影响的一年生杂草。杂草苋菜幼龄叶片形态解剖特征的鉴定有助于更好地了解其在农业生态系统中的表现。本研究采用创新的多尺度方法,通过共聚焦显微镜和相机采集对4种苋属植物约20个单叶形态特征进行了表型分析。结果表明,在不同的调查水平上,叶片性状的测定突出了幼期的种特异性性状,这些性状对植物的发育、竞争和建立至关重要。其中,叶片圆度和毛羽纵横比能较好地区分结核。此外,叶片重、毛面积和周长等变量也有助于区分雌雄异株苋和雌雄同株苋。本文所采用的方法为系统发育相关物种的功能表征以及分类学和生物多样性研究中涉及的性状的统计量化提供了一种有前途、可靠和低影响的方法。

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.
