This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and...

  The aim of the present study was to determine effects of artificial drought stress on the characteristics of germination and seedling growth in bread wheat cultivars. The material of experiment consisted of seeds obtained from eight bread wheat cultivars with different response to drought (Alpu 2001, Sultan 95, Konya 2002, Eser as sensitive cultivars; Karahan 99, Tosunbey, Kate A1 as resista...

in order to study the effects of four concentrations (check, 5, 10 and 15%) of hull extracts on growth of 10 iranian rice cultivars, two experiments were conducted in completely randomized block design with factorial arrangement and three replications at two sites, laboratory and greenhouse. laboratory study showed that same rice hull extracts had stimulat effects and the others had inhibitory ...

this study was conducted at the gorgan university of agricultural sciences and natural resources farm, iran, golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on azivash (corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. treatments were four sowing dates such as may 5, jun 5, ju...

Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...

environmental stress especially drought is one of the most important factors to reduce and disturbance in different stages of floral growth especially sprouting in dry and semi-dry lands of iran. for this purpose a factorial essay executed in accidentally manner with four iterations in vitro condition. four genotypes of bromus tomentellus pasture types were used (92 tehran, 630 kordestan, 3414 ...

in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

a pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (sesamum indicam l.) during seedling development and the early vegetative growth. factors included five priming treatments : control (non priming) , hydropriming, halopriming with nacl, kcl , cac...

Annual Sainfoin (Onobrychis crista-galli (L.) Lam.) is widely adapted to moderate and cold regions of Iran and naturally grows in pasture and rangelands used for forage in these areas. In order to study the effects of priming on seed germination and seedling growth in O. crista-galli, two factorial experiments were conducted based on a randomized complete design with three replications under la...
