In order to study the effects of salt stress and leaf feeding by ascorbic acid on antioxidant enzyme activity, proline accumulation and lipid peroxidation on leaves and roots of Brassica napus L. cvs. Okapi, an experiment was conducted as a factorial in a completely random design with three replications. Plants were exposed to salt stresses by NaCl solution (200 mM) and foliar were treated by a...

In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...

In vitro production is one of the fast and low-cost methods for mass propagation of horticultural crops. But, in vitro plantlets are more sensitive than others and need more adaptation against climatological factors. In order to investigate the symbiosis effects of two species of mycorrhizal fungi on growth and yield of sweet pepper (Capsicum annum L.) cv Inspiration, under drought-stress condi...

The aim of this study was to investigate the effect of organic acid on alleviation of bicarbonate stress in three grafted peach cultivars on GN-15 rootstock. The experiment was performed as a factorial based on a randomized complete block design during 2017-2019. Factors included peach cultivars (Red Haven, Jh. Hale and Barzegar), calcium bicarbonate (0, 7.5 and 15 mM), and a combination of oxa...

Silicon (Si) is a beneficial element for on plant growth and development that plays an important role in plant resistance to environmental stresses such as salinity and drought. The present research was conducted to study the effect of Si and water deficit on biochemical, physio-morphological and qualitative traits of cut rose cv. Club-Nika under greenhouse conditions. The factorial experimen...

Basil (Ocimum basilicum) is a medicinal plant of the family of Lamiaceae. It contains phenylpropanoid and terpenoid componds. Chitosan with elicitor action induce defence mechanisms of plant. In the present study, the effect of chitosan on malondialdehyde (MDA), hydrogen peroxide (H2O2), gayacol peroxidase (GPX) , peroxidase (POD) and poly phenol oxidase (PPO) antioxidant enzymes activity, ph...

In order to evaluate the effect of Inoculation by pseudomonas plant growth promotinh rhizobacteria and  foliar application of boron-nanochelate of pea( Pisum sativum L.) mother plants on germination traits and seedling growth of produced seeds under Cadmium stress a factorial experiment based on completely randomized design with four replications was conducted. Experimental treatments were 12 c...

We conducted a glasshouse experiment as a  factorial in randomized study with six replications on pasture species of Schoenoplectus triqueter in Gonbad Kavoos University from 2012-2013. Treatments included height waterlogging in four levels (control, equal to the water surface, 10 cm below the water surface, 20 cm below the water surface) and waterlogging period over three levels (10, 20 and 30...
