Water stress in mesophytic (non drought tolerant), as opposed to xerophytic (drought tolerant) cultivated species is probably the most common type of plant stress and in many regions is the bottleneck of agricultural development. Based on data collected from various geobotanical regions, Hurvitz (1958) has categorized drought tolerance of cultivated ...

AbstractThe abscisic acid (ABA) content was determined quantitatively in the leaves from wilted and unwilted tomato plants (Lycopersicon esculentum Mill. CV. Revermun) by the use of the wheat coleoptile test and gas‐liquid chromatography (GLC). Plants which have received an insufficient daily water supply for 18 days showed adaptation to wilting ...

Continually applying salt-laden irrigation water to soils can lead to soil salinization because plants leave most of the salts behind as they uptake water. Osmotic potential energy in saline soils is negative and resists the movement of water toward plant roots.

The widening gap between water supply and demand is the biggest threat and challenge before Pakistan. Of the available water, much is polluted. Both scarcity and pollution threaten the agriculture sector, on which the country’s economy depends.

Water Scarcity and Water Stress in Agriculture
2013In the present era of human population growth and climate changes, water scarcity (insufficient hydro-resources with appropriate quality for long-term food and energy production) are recognised as the key environmental issue. In European countries, water scarcity has already affected a significant portion of the territory (>10%) and population (>14 ...

Water is a distinguished stress factor of soils and ecosystems. The description and analysis of positive or negative soil-water stresses are the preconditions of the efficient control of their mechanisms, reversible and/or irreversible consequences. The most significant soil-water stress is extreme moisture regime: water surplus (flood, water-logging ...

ABSTRACTLike some other growth regulators, internal ethylene levels in plants fluctuate as a consequence of water stress and this phenomenon may be responsible for some of the developmental responses which result. Current work seeks to determine how internal ethylene levels are controlled, i.e. by biosynthesis, translocation, diffusion out of the plant

The Sociogenesis of Water Stress
2006This chapter examines the intertwining between environmental and social processes in the transformation of the Basin of Mexico’s hydro-geology and in shaping socio-economic, cultural, and political structures and patterns. It shows how human intervention in the aquatic ecosystems, punctuated by protracted social confrontations, has burdened successive ...
