this experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in iran. the experiment was a factorial design with three replications. treatments were four nitrogen biofrtilizers (control (n1), nitroksin (n2), azotobacter (n3) and supernitroplat (n4)) and three phosphate biofrtilizers ( control(p1), biosfer phosphate (p2) and ...

Seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. Many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. Seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. Du...

Plant-frugivore mutualism serves an important function in multiple ecological processes. Although previous studies have highlighted the effect of frugivore gut passage on fresh seed germinability, no study has investigated the effect on seed storage after frugivore gut passage. We used the endangered plant, Euryodendron excelsum, to determine the combined effects of frugivore gut passage and st...
