“Hungariana,” “Beauty Zest,” and “Home Flavor” hot pepper plants (Capsicum annuum L. var. annuum) were grown with an ample or a limited water supply. The fruits of plants in the water deficit treatment were small, had a proportionally heavier placenta and had a higher concentration of capsaicin. The concentration of capsaicin in the placenta of “Beauty Zest” fruits in the water deficit treatmen...

Nitric oxide (NO) production and amino acid metabolism modulation, in particular abscisic acid (ABA)-dependent proline accumulation, are stimulated in planta by most abiotic stresses. However, the relationship between NO production and proline accumulation under abiotic stress is still poorly understood, especially in the early phases of plant development. To unravel this question, this work in...

Two experiments were conducted to study the effects of water deficit stress on the germination, emergence and seedling growth of sorghum [Sorghum bicolor (L.) Moench] using Completely Randomised Block Design in four replications. Five sorghum cultivars (Jigurti, Gambella 1107, Meko, 76 T1 #23 and P9403) were evaluated under three water deficit stress treatments (0, -0.20 and -0.85 MPa) using PE...

Despite the importance of Artemisia annua L. as the only source of the anti-parasitic drug artemisinin, little is known on the effects of biotic and abiotic stress on artemisinin accumulation. Water deficit is the most limiting factor on plant growth, however it can trigger secondary metabolite accumulation, depending on the plant growth stage and intensity. A. annua cultivated in growth chambe...

knowing and applying the basic management functions of planning, organizing, staffing, directing, and controlling, as well as their permutations and combinations, are vital to effective delivery of public health services. presently, graduate programs that prepare public health professionals neither emphasize teaching management theory, nor its application. this deficit puts those who become man...

according to the global water shortage problem, the exploring for reducing its harmful effects is very important. this experiment was conducted as split plots method based on randomized complete block design with three replicates in urmia university research field during growing season of 2013-14. water deficit stress as main plot consisted of three levels (irrigation when soil moisture reached...

mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...

many factors affect wastewater management and utilization plans’ success with any change occurring in any of these factors leading to various feedbacks on other elements of wastewater use system. hence, development of a model with the capability of simulation of all factors, aspects and interactions that affect wastewater utilization indispensable. the objective followed in this study was to mo...

Trend analysis and estimation of monthly and annual precipitation, reference evapotranspiration ETo, and rainfall deficit are essential for water-resources management and cropping-system design. Rainfall, ETo, and water-deficit patterns and trends at Macon in eastern Mississippi for a 120-yr period (1894–2014) were analyzed for annual, seasonal, and monthly periods. The analysis showed historic...
