概括
植物化通过两种途径发生:化 (适应乱的息地) 和分化 (成为作物的杂草). 粗作物慢慢化,而细作物更快地化,可能涉及有意识的选择.
科学领域:
- 考古植物学 考古植物学
- 进化生物学 进化生物学
- 农业科学 农业科学
背景情况:
- 已经提出了两种主要途径,即鲁德拉和塞格拉,用于植物化.
- 这些路径描述了适应人类改变环境的植物如何成为化作物.
研究的目的:
- 详细介绍原始和细形化途径.
- 为了分析这些路径内的作物的考古植物形态测量数据.
- 推断化事件并计算化特征变化速率.
主要方法:
- 利用了以种子为重点的度量考古植物学数据集.

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.

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
