- 植物生态学植物生态学
- 进化生物学 进化生物学
- 性格特征 进化 演化
背景情况:
- 叶子-种子高度 (LHS) 计划将植物的功能特征 (叶子大小,茎高度,种子质量) 与生命史策略联系起来.
- 以前的研究探讨了跨物种的LHS方案,但不是跨主要植物类.
- 了解特征变异驱动因素对于植物进化和生态学至关重要.
研究的目的:
- 调查LHS方案跨多种植物种群:棕树,其他单种植,双种植和体.
- 确定主要因素驱动植物功能特征的变化,特别是种子质量,在类内和类之间.
主要方法:
- 在选定的植物群中对功能特征 (叶子大小,茎高度,种子质量) 的比较分析.
- 统计检查,以确定树系,叶子大小和植物高度对种子质量变化的影响.
主要成果:

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

02:33Seed Structure and Early Development of the Sporophyte
27.8K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

02:16Light Acquisition
8.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
