Panicle water relations during water stress
Plant Science Letters, 1984Abstract Although the importance of water stress-induced sterility during reproductive stages of cereal development is obvious, little is known about the tissue water relations of the panicle. The water potential and water content of rice panicles were found to be linearly related.

Asian Survey, 2019
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.

Crop Water Stress Index and Yield of Water‐Deficit‐Stressed Alfalfa
Agronomy Journal, 1988AbstractThe yield relationship of water‐deficit‐stressed alfalfa (Medicago sativa L.) with the Crop Water Stress Index (CWSI) may be dynamic over the alfalfa harvest period. This investigation was conducted to define the alfalfa yield‐CWSI relationship(s), to test possible advantages of using the CWSI over the canopy‐minus‐air temperature (Tc−Ta ...

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 ...

The effects of arsenate and arsenite on growth and transpiration were investigated in cucumber plants grown in nutrient solution containing 2, 10, and 100 μM phosphate, respectively. Root and shoot growth decreased by 48–64% compared to the control in all treatments and there was no significant difference between the effects of arsenic As(V) and As(III)

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

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 ...

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.

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 ...

Drymoglossum under Water Stress
American Fern Journal, 1984Drymoglossum is an epiphytic fern found commonly on the trunks of some local trees. It exhibits typical CAM features (Hew & Wong, 1974; Wong & Hew, 1976). It has fleshy fronds for storing water, but it is not uncommon to observe shrivelling of its fronds during dry spells. Different CAM plants seem to respond to drought differently. Under water stress,
