A study was carried out to assess the use of electrolyte leakage measurement to evaluate radiation sensitivity of 13 freshcut vegetables, and correlated radiation sensitivity with endogenous antioxidant capacity. Fresh-cut vegetables were gamma irradiated at doses up to 3 kGy at 0.5 kGy intervals. Electrolyte leakage of the samples was measured following irradiation. Electrolyte leakage increas...

in order to investigate the physiological and morphological traits of seven autumn sugar beet (beta vulgaris l.) cultivars (jolge, palma, giada, monotunno, sbsi1, suprema and pp8), under  freezing stress, a study was carried out as a factorial experiment (7×10) based on randomized complete block design with three replications in college of agriculture of ferdowsi university of mashhad. the plan...

Seasonal changes in freezing stress resistance of needles of red pine (Pinus resinosa Ait.) and Austrian pine (Pinus nigra Arnold) trees were measured by an electrolyte leakage method and by visual observation. During most of the year, freezing stress resistance determined by the two methods gave similar results. The electrolyte leakage method provided a good estimate of seasonal changes in fre...

ajowan is one of the endemic plants in khorasan province, and there is a little information on its tolerance to cold stress. in order to study freezing tolerance of ajowan, an experiment was conducted in faculty of agriculture, ferdowsi university of mashhad, based on factorial-completely randomized design with three replications and three ecotypes of ajowan (neishabour, birjand and torbat-e-he...

ABSTRACT The pepper genotype, ECW-12346, was developed with bacterial spot resistance derived from Pep13, PI 271322, and ECW123 (Early Calwonder containing Bs1, Bs2, and Bs3 genes). For genetic analysis of this resistance, ECW12346, ECW123, F(1), F(2), and backcrosses were inoculated with a pepper race 6 (P6) strain. Two recessive genes were identified that determined resistance. The genes are ...

The objective of this study was to assess changes in membrane permeability during rehydration of freeze-dried Weissella paramesenteroides LC11. Viability was assessed using the electrical conductivity measurement (ms cm -1 g -1 dry weight) and the plate count method (cfu g -1 dry weight). The symptoms of injury included an increase in the electrolyte leakage during the first 4 h of rehydration ...

abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...

in order to study the effects of ascorbic acid as an important antioxidant reducing salinity damage, an experiment was conducted on two althernantera genotypes (“entire leaf” and “undulated leaf”) at research greenhouse of shahid chamran university in 2013. concentrations of 0, 0.5 and 1 mm of ascorbic acid were sprayed weekly on plants grown under 0, 30, 60, 90 mm nacl. the experiment was carr...

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...

in order to investigate the effect of silicon application on some physiological characteristics and growth of wheat (triticum aestivum l.) under late drought stress condition, an experiment was conducted at the agriculture and natural resources university of ramin, khuzestan during year 2012. the experiment was conducted in the open environment as factorial randomized complete block design with...
