Water retaining agent (WRA) is widely used for soil erosion control and agricultural water saving. Here, we evaluated the effects of the combination of beneficial soil bacterium Bacillus amyloliquefaciens strain GB03 and WRA (the compound is super absorbent hydrogels) on drought tolerance of perennial ryegrass (Lolium perenne L.). Seedlings were subjected to natural drought for maximum 20 days ...

Catharanthus roseus L. is an important medicinal plant producing several terpenoid indole alkaloids (TIAs) such as vincristine and vinblastine secondary metabolites with anticancer activity. The TIAs biosynthetic pathways are affected by biotic and abiotic stresses. In this study the effect of drought (7 days), salinity (150 mM NaCl), foliar spray of salicylic acid (10-5 M) and salicylic acid i...

Peanut is an important oilseed and food legume cultivated as a rain-fed crop in semi-arid tropics. Drought and high salinity are the major abiotic stresses limiting the peanut productivity in this region. Development of drought and salt tolerant peanut varieties with improved yield potential using biotechnological approach is highly desirable to improve the peanut productivity in marginal geogr...

Water deficit stress is one of the chief abiotic stresses adversely affecting plant endurance leading serious effects on metabolism. Depending upon strength and duration water conditions, plants adjust a series physiological, cellular molecular mechanisms aiming correct response. Some responses to include decreased growth development hence decrease in fresh biomass, content chlorophyll rate pho...

Non-irrigated crops in temperate climates and irrigated crops in arid climates are subjected to continuous cycles of water stress and re-watering. Thus, fast and efficient recovery from water stress may be among the key determinants of plant drought adaptation. The present study was designed to comparatively analyze the roles of drought resistance and drought recovery in drought adaptation and ...

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Sage (Salvia officinalis L.) is cultivated worldwide especially in Mediterranean regions in which the leaves of this herb are widely used in pharmaceutical and food industries. Brassinolides and paclobutrazol are naturally occurring substances which modulate plant growth and development events and have been known to improve the crops tolerance to biotic and abiotic stresses. The effects of spra...

Photosynthesis is the basic process influencing crop productivity. It can be inhibited by drought. Seven sour cherry genotypes were challenged by drought to assess their photosynthetic efficiency in such conditions. All together with relative water content (RWC) as indicator of plant water status, maximum quantum yield of photosystem II (Fv/Fm) and chlorophyll content (Chl a+b) differentiated i...
