Revista Brasileira de Engenharia de Biossistemas, 2022 For grasses and other crops in general, soil water potential has been widely studied to determine if there is a deficit or excess of water content in the soil. However, the plant water absorption process is not only modulated by soil water potential but

Soil moisture and soybean physiology affected by drought in an integrated crop-livestock system [PDF]
Pesquisa Agropecuária Brasileira, 2016 : The objective of this work was to evaluate the impact of grazing intensities after 11 years of an integrated crop-livestock system, under no-tillage, on soil moisture and soybean physiological parameters during a summer season affected by drought.

Response of Leaf Water Potential, Stomatal Resistance, and Leaf Rolling to Water Stress [PDF]
Plant Physiology, 1980 Numerous studies have associated increased stomatal resistance with response to water deficit in cereals. However, consideration of change in leaf form seems to have been neglected. The response of adaxial and abaxial stomatal resistance and leaf rolling in rice to decreasing leaf water potential was investigated.

Influence of Temperature Gradients on Leaf Water Potential [PDF]
Plant Physiology, 1977 Water potential was monitored at nine locations along single maize (Zea mays L.) leaf blades with aluminum block in situ thermocouple hygrometers. Water potential showed a continuous decrease toward the tip, with a 2- to 4-bar difference between leaf base and tip under both moist and dry soil conditions.

Chloroplast Response to Low Leaf Water Potentials [PDF]
Plant Physiology, 1973 Electron transport in chloroplasts isolated from desiccated sunflower (Helianthus annuus L. cv. Russian Mammoth) leaves was compared with electron transport in sunflower chloroplasts in sorbitol-containing media having various osmotic potentials. In media having low osmotic potentials and dichloroindophenol as electron acceptor, the activity for ...
