This study was conducted on two canola (Brassica napus) cultivars, Okapi a winter type and cold tolerant and Rgs003 a spring type and cold sensitive. Seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °C (day/night, control). At the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°C (day/night, cold treatment) an...

The present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vYaghouti. The experiment was done at Agricultural and Natural Resources Research Center, Ilam, Iran at 2014. The experiment was a completely block design (CRD) with four replications. Saline factor was NaCl salinity in seven levels (Zero, 50, 100, 150, 200 and 250 mM). Grap...

The present study evaluates the genotoxic potential of different soil samples collected from rice fields employing Allium cepa root chromosomal aberration assay using in situ and root dip modes of treatment. The study also involves assessment of oxidative stress by analyzing responses of certain antioxidative enzymes viz. catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), g...

a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...

Bryophytes are poikilohydric organisms that can be used as model plants to study desiccation tolerance mechanisms. The main objective of this was examine the activities antioxidant enzymes ascorbate peroxidase (APX), catalase (CAT) and guaiacol (POD) in rehydrated desiccated states Syntrichia ruralis (Hedw.) Web. & Mohr. from two slopes, one North-east (NE) South-west (SW) facing collected ...

to find out the effect of sodium nitroprusside (snp) in reducing oxidative damage induced by salinity stress in barley 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 two snp levels (0.1 and 0.2 mm snp; as nitric oxide (no) donor) ...

Drought is one of the main abiotic stress factor that limits plant growth and development. effects on Borago officinalis L. (borage) plants in terms physiological antioxidant responses have been evaluated this study. In parallel with purpose, relative rate (RGR), leaf water content (RWC), osmotic potential, chlorophyll fluorescence (Fv/Fm), lipid peroxidation, hydrogen peroxide (H2O2) level, su...

The goal of this study was to identify the zoysiagrass rust pathogens and analyze differences in rust-resistant rust-susceptible Zoysia japonica germplasm upon inoculation. Based on assessment spore morphology 18S ribosomal DNA (rDNA) molecular identification, pathogen identified as Puccinia zoysiae Diet. development mycelium, rate spreading, timing production were more delayed (RR) genotype th...
