Septoria tritici blotch (STB), caused by the ascomycete fungus Mycosphaerella graminicola (asexual stage: Septoria tritici), is one of the most important foliar diseases of wheat. In this research, quantitative expression analysis of five candidate genes for the induction of resistance to STB (PR-1, Bsi, Msr, Per, and Ppi) was conducted in the wheat cultivars ‘Seri 82’ (susceptible) and ‘Fronta...

to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

rapeseed (brassica napus l.) is a crop relatively tolerant to salt. the effect of different ratios of nacl/kcl was studied in two cultivars (hyola308 and kristina) of rapeseed in 2002. canola seedlings were grown in hoagland’s solutions, which were salinized by different ratios of nacl/kcl. the treatments or kcl:nacl ratios were 0:0 (control);10:10; 20:0 (total added salt or tas=20 mol.m-3), 0:...

employment of solarization using the polyethylene mulch can be effective as a non-chemical approach for some control noxious weed management such as purple nutsedge (cyperus rotundus). in order to determine the effect of different levels of polyethylene mulches including one- layer clear polyethylene film, two- layer clear polyethylene film, one- layer black polyethylene film and two- layer bla...

Two spotted spider mite (TSSM), Tetranychus urticae Koch, is an important pests on bean in Markazi Province (center of Iran).
