Background: Plant growth is frequently influenced by the environmental conditions that affect the plant. The objective of the study: The present research work was undertaken to study the response of Withania frutescens to changes in the environmental conditions by investigating topographical, climatological, morphological, histological, and phytochemical aspects that influencing plant growth. Material and Methods: The topography of the study area was described using the Digital Terrain Model (DTM). The bioclimatic study was carried out using a climatological database (TerraClimate) recorded for the periods 1960-1970 as an old period (AP) and 2000-2019 as a new period (NP). The histological study on stems, leaves, and roots was investigated according to protocols as described in the present study. The phytochemical analysis was assessed using gas chromatograph coupled to a mass spectrophotometer after silylation. Results: The topographical study showed that the selected stations were varied in terms of topographical characteristics. The average annual precipitation recorded for the study area is 624 mm/year, and the thermal amplitude is about 34.64°C. The Morphometry study revealed that the plant had changes in length and width from one zone to another. The histometrical study of organs showed also changes in tissue structure over time and space. The phytochemical content in the studied plants was found to be also vary over time and space. Conclusion. Based on the obtained results, we could confirm that W. frutescens has developed different strategies to mitigate hard environmental conditions.

Withania frutescens 的反应。L 在地中海地区生长以适应环境条件的变化：一种适应方法

背景：植物生长经常受到影响植物的环境条件的影响。研究的目的：目前的研究工作是通过调查影响植物生长的地形、气候、形态、组织学和植物化学方面来研究 Withania frutescens 对环境条件变化的响应。材料和方法：使用数字地形模型 (DTM) 描述研究区域的地形。生物气候研究是使用将 1960-1970 年作为旧时期 (AP) 和 2000-2019 年作为新时期 (NP) 记录的气候数据库 (TerraClimate) 进行的。根据本研究中描述的方案对茎、叶和根的组织学研究进行了调查。在硅烷化后，使用与质谱仪联用的气相色谱仪评估植物化学分析。结果：地形研究表明，所选站点的地形特征各不相同。研究区记录的年平均降水量为624毫米/年，热幅约为34.64℃。形态测量学研究表明，植物从一个区域到另一个区域的长度和宽度发生了变化。器官的组织计量学研究还显示组织结构随时间和空间的变化。发现所研究植物中的植物化学物质含量也随时间和空间而变化。结论。根据获得的结果，我们可以确认 W. frutescens 已经制定了不同的策略来缓解恶劣的环境条件。
