Lesquerella fendleri (Gray) S. Wats., a native of the arid and semiarid regions of southwestern US, has been proposed as an important industrial seed oil crop (Thompson and Dierig 1988). Intensive breeding and agronomic research efforts at the US Water Conservation Laboratory have been directed towards domesticating and commercializing the crop (Dierig et al. 1993; Coates 1994; Brahim et al. 19...

Land and water resources are becoming scarce and are insufficient to sustain the burgeoning population. Salinity is one of the most important abiotic stresses affecting agricultural productions across the world. Cultivation of salt-tolerant turfgrass species may be promising option under such conditions where poor quality water can also be used for these crops. Coastal lands in developing count...

Quality of agriculture drain water was assessed from selected locations in Guntur district, Andhra Pradesh, India. Waste samples collected drains were analysed for quality parameters such as pH, electrical conductivity, total dissolved solids, hardness, chlorides, carbonates, bicarbonates, calcium, magnesium, sulphates, phosphates, sodium, potassium, ammonical nitrogen, nitrates oxygen and chem...

BACKGROUND This study investigates the relationship between salinity and biotic communities (primary producers and macroinvertebrates) in Rambla Salada, a Mediterranean hypersaline stream in SE Spain. Since the 1980's, the mean salinity of the stream has fallen from about 100 g L(-1) to 35.5 g L(-1), due to intensive irrigated agriculture in the watershed. Furthermore, large dilutions occur occ...

Adaptation of plants under drought and salinity stress depends directly on the type of soil texture. Therefore, in this research, the morpho-physiological variations of Stachys multicaulis, an Iranian wild endemic plant species, were investigated in different soil textures under drought and salinity stress. For this purpose, plants were cultivated in three different light, medium and h...

introduction water shortage in iran has always been a limiting factor for crop cultivation. drought stress at different growth stages, especially flowering and grain filling stages decreases the yield of the plants. drought stress may limit yield of medicinal and aromatic plants by reducing the harvest index (hi). this can occur even in the absence of a strong reduction in total medicinal and a...
