To find the protective role of exogenous nitric oxide (NO) on salinity-stressed rice seedlings, a CRD-based factorial experiment with three replications was conducted in Agronomy Laboratory of the Faculty of Agricultural Sciences, University of Guilan, in 2012. The experimental design consisted of healthy and vigorous seedlings of two rice cultivars, Khazar and Goohar, the last already known as...

Drought stress is a serious adverse factor that limits sunflower growth and productivity. The stress induces a range of physiological and biochemical responses in sunflower. So, evaluation of defense systems is important for producing resistant cultivars. In this study, physio-biochemical changes and antioxidant enzymes activitiesof six sunflower lines were evaluated under normal and irrigation...

ABSTRACT-Water stress is the main cause for crop yield reduction in the majority of agricultural regions of the world because it affects almost all plant functions. The effects of Glomus mosseae on growth, nutrients uptake, and antioxidant enzymes of sour orange (Citrus aurantium) and rough lemon) Citrus jambheri) rootstocks were assessed in sterilized soil under greenhouse conditions.  A three...

Recently, the use of nanofertilizers has received a great deal attention in managing plants under biotic and abiotic stresses. However, studies that elucidate role silicon dioxide nanoparticles (SiO2NPs) regulating maize tolerance to drought stress are still at early stages development. In this study, were treated with SiO2NPs (0.25 g/L as foliar spray) displayed considerable improvement growth...

Wheat intercropping in watermelon could provide relief from the occurrence of Fusarium wilting watermelon, a severe soil-borne disease caused by fungus oxysporum f. sp. niveum (FON). The current study aims to investigate effect root exudates three wheat cultivars and one cultivar on growth FON responses wilt with wheat. results revealed contrasting effects mycelial FON; inhibited FON, promoted ...

Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...

Low-temperature storage is convenient for postharvest preservation of peach fruit, but fruit sensitive to cold damage, which lowers its quality. Nitric oxide (NO) has the potential improve bitter resistance fruit. In this work, was treated with 15 ?mol L?1 NO and 5 c-PTIO [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxo-3-oxide], study changes in mitochondrial fatty acids expression C-...
