Parameters that show a significant genotypic variation at early growth stages and are associated with salt tolerance at later stages may be used as rapid and economic screening criteria in breeding programs. The objective of this study was to test growth parameters at early growth stages for evaluating the salt tolerance of wheat genotypes. Ten wheat genotypes that differ from their salt tolera...

in order to evaluate the physiological and biochemical traits in response to salinity, six varieties of wheat were cultivated in a split plot based on randomized complete block design in the growth chamber in the department of agronomy, faculty of agriculture, university of maragheh. seedlings of wheat cultivars, in three to four leaves stage were treated with 200 mm nacl for 14 days. after the...

Five strains of Trichoderma with known biocontrol activities were assessed for their effect upon pea growth and their antagonistic activity against large Pythium ultimum inocula. The effect of Trichoderma inocula upon the indigenous soil microflora and soil enzyme activities in the presence and absence of Pythium is assessed. In the absence of Pythium, Trichoderma strain N47 significantly incre...

in order to evaluate the effects of biofertilizer on soybean (glycine max l.) seed vigor that produced under water deficit condition and related traits, an experiment was conducted in a factorial layout based of complete randomized block design with four replications at the research greenhouse of aboureihan campus- tehran university, iran. experimental treatments were include biofertilizer (see...
