Salinity and water deficit [PDF]

open access: possible, 2020
Drought and salinity are among the environmental factors that constrain citrus productivity most dramatically. The citrus crop is predominantly cultivated in arid and semiarid regions under irrigation conditions, giving rise to problems frequently associated with salt stress rather than water deficit.

Water relations in sugarcane and response to water deficits

Field Crops Research, 2005
Abstract Knowledge of water relations is fundamental to improved crop management in regions where irrigation is practiced or where dry conditions cannot be avoided. The objective of this review was to assess where knowledge of sugarcane water relations must be strengthened in order for progress to be made in irrigation management as well as genetic ...

Crop Water Deficits

1976
Publisher Summary This chapter emphasizes the measurement of plant water potential following the realization of the importance of atmospheric demand in determining plant water deficits. The total water potential concept determines the movement of water through the soil-plant-atmosphere continuum in response to gradients in water potential and of the ...

Comparison of Drought Probability Assessments Based on Atmospheric Water Deficit and Soil Water Deficit

Agronomy Journal, 2013
Methods that estimate the probability of agricultural drought using atmospheric data can be widely applied but have not been compared with actual drought occurrence indicated by soil moisture measurements. Our objectives were to develop a drought probability assessment method using long‐term measurements of soil water deficits (SWDs) and to compare the

Deficit Irrigation and Water Conservation

2020
In this chapter, we tackled some of the concepts and definitions used in application of deficit irrigation instead of full irrigation as a technology aims at conserving irrigation water. Both water use efficiency and water productivity are important estimators in the assessment of the effect of deficit irrigation.

Water deficit tolerance in genotypes of Urochloa spp.: Water deficit in Urochloa spp.

2021
It is estimated that the world’s population will increase considerably in the coming years. Thus, there is a need to maximize the production of animal protein, of which the pasture production system is the most economical way. However, abiotic factors influence animal production, with water deficit being the factor that most limits the development of ...

Water deficit in plant communities

Canadian Journal of Botany, 1970
Comparative investigations within the two different plant communities of Croatia (Fagetum silvaticae croaticum abietetosum Ht and Querco-Carpinetum croaticum erythronietosum Ht) indicate that (1) the two communities have their own range of water deficit values, (2) the Dw values are dependent on the capability of the species to regulate their water ...

Effect of water-deficit on tassel development in maize

Gene, 2019
Maize often exhibits asynchronous pollination under abiotic and biotic stress conditions; however, the molecular basis of this developmental deficiency has not been elucidated. Tassel development is a key process affecting the anthesis-silking interval (ASI) in maize.

Plant responses to water deficit

Trends in Plant Science, 1997
Plant responses to water deficit are dependent on the amount of water lost, the rate of loss and the duration of the stressed condition. The characterization of a large number of genes induced by stresses involving water deficit has significantly improved understanding of the response.

Acclimation of Photosynthesis to Water Deficits

1984
Photosynthesis (Ps) is inhibited at low leaf water potentials (Ψ). Generally, both stomatal and chloroplast functions are affected such that the supply and utilization of CO2 are decreased. Although sto-matal closure generally occurs when plants are exposed to water deficits, in some cases Ps may be more limited by chloroplast capacity to fix CO2 than ...
