Abstract
To assessment effect of concentration and times of disinfection wheat seeds, infected byAspergillus fungus a research was conducted based on Factorial experiment accordingrandomized complete block design with four replications. The factors included four levelsof sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and10 minutes). Result of analysis of variance indicated interaction effect of treatments ongermination percentage (p≤0.05), Radicle length (p≤0.05), plumule lentgh (p≤0.05),germination rate (p≤0.05), seed dry matter (p≤0.01), speed of germination (p≤0.05) andseedling dry matter (p≤0.01) was significant, but on mean of germination time, radicle dryweight, plumule dry weight and abnormal bud was not significant. Germination rate asimportant trait had significant relation with seedling dry matter (0.992**), radicle length(0.990**), germination percentage (0.983**), plumule length (0.982**), speed of germination(0.981**), seed dry matter (0.924**) and abnormal bud (-0.767*). Treatment of 6%concentrations of sodium hypochlorite along 7 minute had highest amount of Seed drymatter (0.0899 gr), speed of germination (38.991 day), seedling dry matter (0.1899 gr),germination percentage (98.87 %), radicle length (11.40 cm), plumule length (10.91 cm),germination rate (39.98 day), so it possible to advised for improve wheat seed germinationparameters.
