Drought has become a critical environmental stress affecting on plant in temperate area. As one of the promising bio-energy crops to sustainable biomass production, the genus Miscanthus has been widely studied around the world. However, the most widely used hybrid cultivar among this genus, Miscanthus × giganteus is proved poor drought tolerance compared to some parental species. Here we mainly...
The production of various reactive oxygen species (ROS) is one of the effects of drought stress on plants. In order to combat with them, enzymatic antioxidant is presented in plant cells. In this study, the ability of adaptation of three native rangelands species (Taverniera cunifolia, Lycium shawii and Rhazya stricta) with multiple capabilities such as soil conservation, medicinal and orna...
Drought stress is a limiting factor for production in agriculture. In order to evaluate the impact of plant growth regulators, Salicylic acid and Paclobutrazol on growth and physiological traits of Sweet Basil (Ocimum basilicum) under drought stress condition, a factorial pot experiment based on Randomized complete design with 4 replication was carried out at research greenhouse of Mohaghegh Ar...
A moderate water deficit stress (S1) applied 10 days after anthesis was found to induce acclimation to a subsequent more severe drought stress (S2) in Solanum lycopersicum L.. When plants were pretreated with S1, and then subjected to S2, fruit water status remained similar to controls. In contrast, S2 induced a decrease in both parameters of water status and diameter of fruits from non-acclima...
Drought Stress is one of the most important limiting factors in plants growth and development. Growth regulator, Trinexapac-ethyl, might improve drought stress resistance via reducing stem growth and improving osmotic adjustments. In present study Trinexapac-ethyl effect on some tall fescue var Rebel physiological and morphological traits under irrigation free conditions was studied. So, an exp...
Drought stress is one of the limiting factors for plant growth and yield all over the world. Stevia rebaudiana from semi-humid area of Paraguay contains steviol glycosides with pharmacological properties. In the present study, the callus obtained from Stevia rebaudiana were treated with different treatments of poly ethylene glycol, paclobutrazol and gibberellin under in vitro culture and then s...
A pot experiment was conducted to determine the response of two recent forage sorghum cultivars (JS-2002 and Chakwal Sorghum) and an old one (JS-263) to three levels of soil moisture (30%, 50% and 70% field capacity). Several traits were assessed addressing plant morphology, functional growth, leaf water status, biomass yield and water use efficiency (WUE). Soil moisture variation greatly affec...
Aim. Drought is one of the most harmful abiotic stresses limiting crop productivity. We study ability photosynthetic apparatus winter wheat varieties differing in their tolerance to acclimate moderate drought stress under pot experiment. Methods. Dynamics relative water content (RWC), chlorophyll content, CO2 assimilation rate (Pn), activity antioxidant enzymes chloroplasts flag leaf drought-to...
environmental stresses trigger a wide variety of plant responses, such as altered gene expression to changes in cellular metabolism and growth. the several plant reactions exist to circumvent the potentially harmful effects caused by light, drought, salinity, pathogen infections and other stresses. a-tocopherol is the major vitamin e compound found in leaf chloroplasts. this antioxidant deactiv...
CBP20 (Cap-Binding Protein 20) encodes a small subunit of the cap-binding complex (CBC), which is involved in the conserved cell processes related to RNA metabolism in plants and, simultaneously, engaged in the signaling network of drought response, which is dependent on ABA. Here, we report the enhanced tolerance to drought stress of barley mutant in the HvCBP20 gene manifested at the morpholo...
