Leaf water potential measurements using the pressure chamber: Synthetic testing of assumptions towards best practices for precision and accuracy. [PDF]
Plant Cell Environ, 2022 Leaf water potential (ψ leaf), typically measured using the pressure chamber, is the most important metric of plant water status, providing high theoretical value and information content for multiple applications in quantifying critical physiological ...

Should we delay leaf water potential measurements after excision? Dehydration or equilibration? [PDF]
BMC Plant BiologyBackground Accurate leaf water potential (Ψw) determination is crucial in studying plant responses to water deficit. After excision, water potential decreases, even under low evaporative demand conditions, which has been recently attributed to the ...

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

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.

Physiological responses of wheat (Triticum aestivum L.) to deficit irrigation and sowing density [PDF]
Iran Agricultural Research, 2021 To evaluate the effect of sowing density (300, 400, 500, 600 and 700 plants/m2) on the growth of wheat under deficit irrigation (100, 75 and 50% crop water requirement, I100, I75 and I50, respectively), an experiment was carried out during 2009 and 2010.
