Abstract :
This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and C4= 8%) and four time use of NaClO (T1= 2, T2= 5, T3= 7, and T4=10 minutes). Result showed germination percentage and seedling dry weight, seed vigor index and seedling length had positive and significant relationship, but with percentage of abnormal seedling had negative and significant relation. Seedling growth rate with radicle length and plumule length had positive and significant relationship. Germination rate and mean germination time had negative and significant relationship. In general, it can be concluded that higher germination percentage led to increase seedling dry weight and seedling length also higher seed vigor index cause to improve germination percentage especially under environmental contaminants situation. Although lower germination percentage led to increase percentage of abnormal seedling. The higher radicle and plumule length depends to seedlings growth rate. Increasing seed quality and disinfection of the environment leads to an increase germination rate and a decrease mean germination time.
