Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Land‐Atmosphere Coupling Is Associated With Severer Vegetation Productivity Losses During Compound Dry‐Hot Events in Drylands

International Journal of Climatology, EarlyView.
Compound dry‐hot events (CDHEs) exerted severer damage on vegetation productivity for temperate shrublands, savannas and grasslands in drylands. Land‐atmosphere coupling was associated with severer negative impacts of CDHEs through soil moisture–temperature feedback, especially for dry‐event‐leading CDHEs.

Wheat Wild Relatives and Modern Cultivars Differ for Salt Resistance in Terms of Morpho‐Physiological Traits

Journal of Plant Nutrition and Soil Science, EarlyView.
Wheat wild relatives are untapped genetic resources from salinity and drought hit areas. This study presents differential comparative morphophysiological responses of these species and modern wheat cultivars under saline conditions. Salt resistant species produce more shoot and root biomass under saline conditions through salt exclusion and/or tissue ...

Effects of Microplastic Pollution on Growth, Photosynthesis, and Nutritional Composition of Maize (Zea mays L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Microplastic (MP) contamination in agroecosystems is an increasingly recognized environmental concern, whereas its polymer‐specific impacts on plant growth and nutritional composition remain poorly understood. Aim Our study aimed to evaluate how polymer type and concentration of MPs directly affect plant growth, physiological traits,

An evaluation of the effects of over-production of ABA on whole plant water use, growth and productivity [PDF]

Predicted climate change and increasing global populations suggest that water will become an increasingly scarce and valuable commodity. Breeding plants which produce equivalent yields with reduced water input is therefore vital to sustain and ...

Accounting for sap flow from different parts of the root system improves the prediction of xylem ABA concentration in plants grown with heterogeneous soil moisture. [PDF]

, 2008
When soil moisture is heterogeneous, sap flow from, and ABA status of, different parts of the root system impact on leaf xylem ABA concentration ([X-ABA]leaf). The robustness of a model for predicting [X-ABA]leaf was assessed.

A mathematical model for the estimation of stomatal conductance

Journal of Physics: Conference Series
Abstract Global climate change has significantly impacted plants in Mediterranean-type climate areas, with heatwaves and reduced rainfall leading to more frequent and severe droughts. In this context, stomatal conductance plays a fundamental role in the exchange of gases between the atmosphere and vegetation, particularly in relation to ...

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.
