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 ...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

effect of free and symbiotic nitrogen fixing bacteria on seed and seedling produced seeds under deficit irrigation was conducted in laboratory and field experiments in 2006. in laboratory of karaj’s seed and plant research and certificate institute an experiment was conducted based on factorial in form of completely randomized design with four replications and in field’s of islamic azad univers...

Ergosterol, a membrane sterol found in fungi but not in plants, was used to estimate live mycelial biomass in ectomycorrhizae. Loblolly pine (Pinus tueda L.) seeds were sown in April 1993 and grown with standard nursery culture practices. Correlations between total seedling ergosterol and visual assessment of mycorrhizal colonization were high during July and August but low as ectomycorrhizal d...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...

The effects of salt stress and auxin on germination factors of three wheat cultivars viz. Sepahan, c-84-8, and c-83-1 were studied under controlled conditions. Germination was assessed using three replicates of 25 seeds in a factorial lay out in Completely Randomized Design (CRD) testing combinations of three levels of salinity (0, 4, and 8 dSm-1 NaCl) and three levels of auxin (0, 0.5, and 1 p...

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 ...
