This study focuses on the growth and morpho-physiological responses of Malaysian commercial variety MR219 rice to salinity stress during early vegetative stages, specifically germination five-leaf stage. For responses, seeds were grown for 10 days in different salt concentrations. Low significantly improves seed increases total number germinated seeds. However, higher (160 mM NaCl) inhibits red...
Grafted rootstocks of fruit vegetables have been widely used in recent years. Due to the availability of local pumpkin germplasms, identification and selection of the landraces resistant to salinity and introducing for production of hybrid rootstocks is necessary. By grafting Spadana cucumber on 3 local landraces ofcucurbits (pumpkin, squash and bottle gourd), 3 imported hybrids of Ferro,19-64 ...
Drought stress, as the most important environmental stress, severely disrupts plant growth and limits production and yield more than any other environmental factor. Investigation of the role of drought stress conditions on plant morphological, physiological and photosynthesis characteristics may provide a tool to understand the basic drought resistance. To investigate the drought tolerance of I...
Environmental challenges to plants typically entail retardation of vegetative growth and delay or cessation of flowering. Here we report a link between the flowering time regulator, GIGANTEA (GI), and adaptation to salt stress that is mechanistically based on GI degradation under saline conditions, thus retarding flowering. GI, a switch in photoperiodicity and circadian clock control, and the S...
To evaluate the resistance of promising chickpea ecotypes to freezing temperatures, an experiment with eight promising cold tolerant chickpea was performed. The ecotypes consisting of 4301, 4322, 4360, 4361, 4366, 4380, 4715, 4816 along with a sensitive one (304) were sown in pots at natural conditions. All the chickpea ecotypes were exposed to freezing temp eratures at controlled conditions d...
in order to study the response of coriander medicinal plant to salt stress, two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. the treatments were salinity at five concentrations including 0, 25, 50, 75 and 100 mm nacl. response of coriander seeds germination in...
Droughts are increasing in severity and frequency, yet the mechanisms that strengthen ecosystem resilience to this stress remain poorly understood. Here, we test whether positive interactions in the form of a mutualism between mussels and dominant cordgrass in salt marshes enhance ecosystem resistance to and recovery from drought. Surveys spanning 250 km of southeastern US coastline reveal spat...
In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...
Salinity stress reduces plant metabolic activity, which reduces plant growth in saline environments. this study aimed to investigate the effect of salinity stress as one of the limiting factors of plant growth and the effect of nanoparticles on stress conditions as one of the auxiliary factors in plant control against stressful conditions by studying physiological factors such as soluble sugars...
experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...
