abstract seed germination is an important phase of plant development during which soil water availability is crucial. salinity can affect seed germination in two ways: 1) change of osmotic potential of available water, 2) toxicity effects. in this experiment, interactive effects of salinity and water deficit on germination criteria of two species of a, littoralis and a. logopoides were studied ...

water deficit, ultraviolet radiation and carbon dioxide enrichment are the most important environmental factors in global climate change. this research was conducted in tarbiat modares university, research greenhouse and the objective of that was to study the effects of three levels of carbon dioxide (500, 900 and 1300 ppm), uv-radiation (uv-a, b and c with intensity of 18, 25 and 40 µw.cm2 res...

BACKGROUND WRKY proteins, which comprise one of the largest transcription factor (TF) families in the plant kingdom, play crucial roles in plant development and stress responses. Despite several studies on WRKYs in wheat (Triticum aestivum L.), functional annotation information about wheat WRKYs is limited. RESULTS Here, 171 TaWRKY TFs were identified from the whole wheat genome and compared ...

Activated water irrigation has been widely investigated as an effective production increasing measure. However, the response of activated in plant growth and use efficiency (WUE) with amount is not well understood. Here, a pot experiment was conducted to determine effects on winter wheat growth, yield, WUE under amount. Twelve treatments included four types, (i) tap (TW), (ii) magnetization (MW...

The effectiveness of chitosan zinc oxide nanoparticles (CS-ZnO-NPs) on growth and yield wheat (Triticum aestivum L., Sakha-93), content water use efficiency (WUE) under stress were investigated. A pot experiment was conducted in a completely randomized design by foliar application CS-ZnO-NPs. Wheat plants sprayed four times at 15, 30, 45 60 days after sowing. treatments were: control (treated w...

BACKGROUND Drought is a common stress limiting crops growth and productivities worldwide. Water deficit may increase cellular membrane permeability, resulting in K outflow. Internal K starvation may disorder plant metabolism and limit plant growth. However, it is seldom reported about the effects of external K on drought tolerance of contrasting wheat cultivars. METHODOLOGY/PRINCIPAL FINDINGS...

this study was performed to investigate the effect of putrescine and spermine on some physiological and biochemical characteristics and antioxidant enzymes activity of peach (prunus persica cv. alberta) and almond (prunus dulcis cv. rabi) seedlings under water deficit. the first factor was water regime at two levels (80% or 50% of soil available water), and the second factor was polyamine treat...
