摘要

植物已经进化出各种适应能力来应对各种环境压力,如干旱、盐度、极端高温和干旱。这些适应包括深入土壤的根系,与真菌的共生关系,以及根系改造以应对水分胁迫。干旱是一种主要的环境压力,可能对植物生长和生产力产生负面影响。植物已经进化出各种适应能力来应对缺水、干旱、盐度和极端温度。深层根系、气孔调节和叶片变化对于从深层土壤获取水分至关重要,而浅层根系则有利于土壤水分不足的地区。渗透调节、离子转运和固存以及形态适应有助于植物维持膨压和水分吸收。遗传适应性可以帮助在盐碱地培育耐盐作物。

Plant Adaptations to Extreme Environments: Survival Strategies for Plants in Harsh or Unique Habitats -A Review
Plants have evolved a variety of adaptations to cope with various environmental stresses, such as drought, salinity, extreme heat, and drought. These adaptations include deep-soil-accessing root systems, symbiotic relationships with fungi, and root system modifications to deal with water stress. Drought is a major environmental stress that can have a negative impact on plant growth and productivity. Plants have evolved a variety of adaptations to cope with water stress, drought, salinity, and extreme temperatures. Deep root systems, stomatal regulation, and leaf modifications are essential for accessing water from deep soil layers, while shallow root systems are beneficial for areas with insufficient soil moisture. Osmotic adjustment, ion transport and sequestration, and morphological adaptations help plants maintain turgor pressure and water uptake. Genetic adaptations can help develop salt-tolerant crops for saline soils.
