The text discusses the effects of drought and other environmental stressors on plants. These include an increase in leaf senescence, drooping, scorching, limp leaves, and other signs of damage such as wilting and defoliation. Drought and salinity can also result in cellular dehydration and reduced cell growth and shoot growth. The effects of drought on plants can also extend to their reproductive capabilities, with impaired germination and reduced seedling vigor. Plants have mechanisms to withstand drought stress, such as curtailed water loss and enhanced photosynthesis. However, prolonged drought stress can lead to complex changes in biochemical, physiological, and morphological aspects of plants. This can make them more susceptible to diseases and other stressors, such as de-icing salts and excessive light. Overall, drought stress can lead to a loss of turgor in plants and ultimately impact their health and survival.
