drought is the most common environmental stresses that affects plant growth. to study the combined effects of arbuscular mycorrhizal fungi (glomus intratadices) and jasmonic acid on growth and ecophysiologycal characteristics of pistachio seedlings cv. qazvini under drought stress, a greenhouse experiment was conducted in a completely randomized design with three replications. experimental fact...
BACKGROUND Drought is a major abiotic stress that affects crop productivity worldwide. Sugarcane can withstand periods of water scarcity during the final stage of culm maturation, during which sucrose accumulation occurs. Meanwhile, prolonged periods of drought can cause severe plant losses. METHODOLOGY/PRINCIPAL FINDINGS In a previous study, we evaluated the transcriptome of drought-stressed...
considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...
In field conditions, plants are concurrently exposed to multiple stresses, where one stressor impacts the plant's response to another stressor, and the resultant net effect of these stresses differs from individual stress response. The present study investigated the effect of drought stress on interaction of chickpea with Pseudomonas syringae pv. phaseolicola (Psp; foliar pathogen) and Ralstoni...
In order to study effect of the various levels of drought and salinity stress (0, -4, -8, -12, -16 bar) on morphological, physiological and biochemical traits of Atriplex halimus in seedling stage under hydroponic culture, two separated experiments were conducted as completely randomized design in three replications in hydroecology laboratory of Gonbad Kavous University...
Due to the limited Alyssum habitats (Alyssum homalocarpum) in rangeland ecosystems, it is necessary to study various aspects of plant growth under different environmental conditions such as abiotic stresses. The aim of this study was to evaluate the effect of salinity and drought on Alyssum seed germination characteristics in laboratory conditions. The experiment was conducted based on complete...
Bermudagrass (Cynodon dactylon) is one of tolerant grass species to drought and salt. The comparative analyses of bermudagrass in response to drought and salt stresses at the physiological, proteomic, and metabolomic levels were performed in this study. The physiological results indicated that osmolytes accumulation, ROS level and antioxidant enzyme activities were extensively changed by drough...
Drought stress is one of the most important limiting factors for cultivation and production of grapes in the world and Iran. To study the effect of drought stress on some physiological traits of three cultivars, i.e. ‘Fakhri’, ‘Molaei’ and ‘Ghalati’, a factorial experiment in completely randomized design with three soil water potential treatments. i.e. -0.2 (control), -0.7 and -1.2 MPa was impl...
In a greenhouse experiment aimed to compare drought resistance, photosystem II efficiency was evaluated using chlorophyll fluorescence parameters and chlorophyll content of four pistachio (Pistacia vera L.) rootstocks based on a completely randomized design (CRD) as factorial with drought treatment (PEG + Hoagland solution) at four levels (0, -0.5, -1 and -2 MPa) and four pistachio rootstocks(A...
Water deficit is a common and major constrain for agricultural production in arid and semi-arid parts of the world like Iran, to the extent that it might threaten the nation’s food security in years to come. Seed germination is a crucial growth stage that is often affected by environmental stresses, including drought. This study investigated the effects of four levels of water potential (i.e. 0...
