Article Synopsis
  • * Research indicates that populations from forest plantations have noteworthy shoot growth and moderate chlorophyll levels, while agricultural field populations demonstrate robust biomass and enhanced photosynthetic capacity, like higher chlorophyll and carotenoid levels.
  • * Roadside populations exhibit adaptations like deeper roots and greater leaf expansion but show reduced biomass; they're able to cope with environmental stress despite lower overall growth compared to other habitats.

Phreatophytes play an important role in maintaining the ecological services in arid and semi-arid areas. Characterizing the interaction between groundwater and phreatophytes is critical for the land and water management in such areas. Therefore, the identification of key traits related to mitigating desertification in differently adapted T.

Parthenium weed poses significant threats to cropping systems, socioeconomic structures, and native ecosystems. The pronounced impact is primarily attributed to its rapid and efficient invasion mechanism. Despite that the detrimental effects of Parthenium weed are widely acknowledged, an in-depth scientific comprehension of its invasion mechanism, particularly regarding modifications in structural and functional attributes under natural conditions, is still lacking.

Withania coagulans is a valuable medicinal plant with high demand, but its wild growth and local usage pose a threat to its natural habitat. This study aims to understand the plant's growth, anatomy, and physiology in different environmental conditions to aid in conservation and re-vegetation efforts. Fifteen differently adapted populations of Withania coagulans were collected from diverse ecological regions, viz.

Article Synopsis
  • L. is a resilient perennial grass found in various environments, including harsh deserts, with a study focusing on its adaptations to aridity in Punjab, Pakistan.
  • Populations thriving in extreme dryness showed notable structural changes, such as increased root epidermal and leaf thickness, alongside a decrease in root pith cell area.
  • Key survival strategies for these grass populations included the accumulation of organic osmolytes like glycinebetaine and proline, which help retain water and manage stress in arid conditions.
