Information on industrial hemp (Cannabis sativa) water use and stress is sparse. We studied impact in two essential-oil cultivars (‘Wife’ ‘Cherry’) prompted by anecdotal differences growth use. In a greenhouse setting, we measured relations, use, growth, essential oil (CBD-cannabidiol THC-delta-9 tetrahydrocannabinol) concentrations. Water did not significantly affect THC CBD concentrations, bu...

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...

In a greenhouse study we quantified the gradual change of gas exchange, water relations and root reserves of aspen (Populus tremuloides Michx.) seedlings growing over a 3-month period of severe water stress. The aim of the study was to quantify the complex interrelationship between growth, water and gas exchange, and root carbon (C) dynamics. Various growth, gas exchange and water relations var...

in this research, some of the echo-physiological characteristics of pistachio trees were studied to understand crop response to drought stress and determine the best irrigation interval. this experiment was carried out in an orchard with a sandy loam textured soil and a commercial cultivar of pistachio named ouhadi grafted on pistacia vera l. rootstock for three years. the irrigation system sel...

Groundwater depletion is becoming a serious policy concern in many developing countries but little is known about the costs of groundwater depletion. I use annual deviations of depth to groundwater from 1999 to 2003 from the 1985-1995 decadal means for Indian districts, to investigate how production and sown area respond to groundwater fluctuations. I find that a 1 meter decline in groundwater ...

Erythrocyte glutathione depletion has been linked to hemolysis and oxidative stress. Glutamine plays an additional antioxidant role through preservation of intracellular nicotinamide adenine dinucleotide phosphate (NADPH) levels, required for glutathione recycling. Decreased nitric oxide (NO) bioavailability, which occurs in the setting of increased hemolysis and oxidative stress, contributes t...

Heat waves that trigger severe droughts are predicted to increase globally; however, we lack an understanding of how trees respond to the combined change of extreme temperatures and water availability. Here, we studied the impacts of two consecutive heat waves as well as post-stress recovery in young Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir) and Robinia pseudoacacia L. (black locust) g...

Chloroacetaldehyde (CAA) is a chlorination by-product in finished drinking water and a toxic metabolite of a wide variety of industrial chemicals (e.g. vinyl chloride) and chemotherapeutic agents (e.g. cyclophosphamide and ifosfamide). In this research, the cytotoxic mechanisms of CAA in freshly isolated rat hepatocytes were investigated.CAA cytotoxicity was associated with reactive oxygen spec...

Water scarcity is increasing in the world, which limiting crop production, especially water-limited areas such as Southern High Plains of United States. There a need to adopt irrigation management practices that can help conserve water and sustain production areas. A 2-year field study was conducted during summers 2019 2020 evaluate effect deficit levels cultivars on root distribution pattern, ...
