Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region. We attempted to identify the relationship between drought and excess moisture tolerance through evaluation of a set of elite maize inbred lines, including lines with known performance under drought, excess moistu...

Most meteorological soil moisture budgets do not account for soil moisture stress changes in the drying cycle or for changes in ground cover or expanding root system. A simple modulated technique is described which considers these factors. Soil moisture stress determined by this technique has a significantly higher correlation with wheat yield than does moisture stress determined by R common me...

to assess moisture stress tolerance at the reproductive growth stage in 11 promising genotypes of spring rapeseed (brassica napus l.), two field experiments were conducted in two growing seasons (2008-2010) at the agricultural research center of safiabad, dezful, iran. genotypes were sown under two non-stress (well-irrigated) and moisture stress (irrigation ceased at flowering) conditions using...

Little is known about phosphorus metabolism in plants suffering from moisture stress. Several metabolic processes, which are completely dependent upon phosphorylated intermediates, are noticeably affected by moisture stress conditions. Photosynthetic rate decreases markedly in severely stressed plants (13). Rate of fixation of CO2 in the dark decreases (12). Above a diffusion pressure deficit (...

the research was conducted in order to determine the bending stress, young’s modulus, shearing stress, and shearing energy of safflower stalk as a function of moisture content and stalk region. the bending forces were measured at different moisture contents and the bending stress and the young’s modulus were calculated from these data. for measuring the shear forces, the stalk specimens were se...

Laminated composite structures operating in a marine environment are subject to moisture ingress. Due to the slow diffusion process of moisture, the distribution of moisture is not uniform so that the laminates can develop hygrothermal stresses. An accurate prediction of the moisture concentration and the associated hygrothermal stress is vital to the understanding of the effect of marine envir...

Light use efficiency (LUE) is a key biophysical parameter characterizing the ability of plants to convert absorbed light to carbohydrate. However, the environmental regulations on LUE, especially moisture stress, are poorly understood, leading to large uncertainties in primary productivity estimated by LUE models. The objective of this study is to investigate the effects of moisture stress on L...

abstract this research was conducted in toroq experimental field station, mashhad, iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. moisture stress treatments (at seven levels) were assigned to main plots, including: d1 ( full irrigation), d2 (no irrigation from one-leaf to double ridge) stag...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...
