The aim of this study was to determine the effects of water stress on the anatomy of xylem and phloem vessels, mesophyll and epidermal cells, relative water content and ion transfer rate of two wheat cultivars including Azar2 as drought tolerant and Shole as drought susceptible cultivars at four leaf stages. Seeds were sown in pots under normal (soil water content at 100% of FC) and the water s...
A portable unilateral nuclear magnetic resonance (NMR) instrument was used to detect in field conditions the water status of leaves of herbaceous crops (Zea mays, Phaseolus vulgaris), mesophyllous trees (Populus nigra), and natural Mediterranean vegetation characterized by water-spending shrubs (Cistus incanus) and water-saving sclerophyllous trees (Quercus ilex). A good relationship was observ...
In order to study the effect of seed priming on morphophysiological characteristics of seedlings of chickpea (Cicer arietinum L.) under salinity stress, a factorial experiment based on completely randomized design with three replications was conducted at the Research Center for Plant Sciences, Ferdowsi University of Mashhad, Iran, in 2011. In this study, osmotic solutions of NaCl with electri...

This study was designed to investigate the effect of Mycorrhiza symbiosis on some orphophysiological characteristics of four different pistachio rootstocks under salinity stress. This research was conducted in a completely randomized design with factorial arrangement with three factors. The factors were included rootstocks at four levels (Badami-e Riz Zarand, Qazvini, Sarakhs, and UCB1), mycorr...
Trait-based approaches have been widely applied to investigate how community dynamics respond to environmental gradients. In this study, we applied a series of maximum entropy (maxent) models incorporating functional traits to unravel the processes governing macrophyte community structure along water depth gradient in a freshwater lake. We sampled 42 plots and 1513 individual plants, and measur...

In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...
the possible alleviating effects of salicylic acid on protection of cowpea (vigna unguiculata) cv. parastu under water stress conditions were investigated in the university of zanjan agriculture research station during 2008. water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, fws) and when 50% of the pods grew 2-3cm (pod-formation water stress, pfws). sa...
in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...
