In calcareous and alkaline soils, which include most of Iran soils, iron deficiency is prevalent. The main cause of iron deficiency chlorosis is high pH of soil. Among fruit trees, peach shows high sensitivity to iron deficiency. Chelated iron fertilizers with a great ability to make iron soluble and readily absorbed by the plant are used for iron deficiency. For this purpose, an experiment bas...

In this study, the effects of postharvest application of γ-aminobutyric acid (GABA), methyl jasmonate (MeJA) and methyl salicylate (MeSA) on chilling injury, peel attributes and fruit juice quality of ‘Moro’ blood orange during cold storage at 3 °C and 90% RH for 150 days was investigated. GABA treatment at concentrations of 20 and 40 mM using vacuum at 30 kPa for 8 minutes and MeJA and MeSA va...

Drought stress is one of the most important restricting factors for plant yield in arid and semi-arid regions. Seaweed extract, as a biofertilizer, enhances plant resistance against abiotic stresses via accelerating seed germination, root growth enhancement and uptake of plant nutrients. The present research was carried out to investigate the effects of foliar spraying of Ascophyllum nodosum se...

A factorial experiment in hydroponic conditions was conducted to evaluate the activity of antioxidant enzymes, membrane stability and Na concentration in seedling of some rice cultivars, in 2014 summer in Ramin Agriculture and Natural Resources University of Khuzestan. Experimental factors were included salinity levels of NaCl (0, 4 and 8 ds.m-1) and rice cultivars (Amol3, Daniel, Shafagh, Fajr...

One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...

Plants with tropical origin including those of the Cucurbitaceae family are generally sensitive to chilling stress and harmed by low temperatures. In this study, we evaluated five plant growth regulators and compared the effectiveness of each substance in improving chilling stress tolerance of cucumber (Cucumis sativus L., cv. Super dominos) seedlings. The experiment was conducted as a randomiz...
