Determination Sodium Hypochlorite (NaClO) Application on Quantitative Parameters of Wheat (Triticum aestivum L.) Seed and Correlation Between Measured traits

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance indicated interaction effect of treatments on germination 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) and seedling dry matter (p≤0.01) was significant, but on mean of germination time, radicle dry weight, plumule dry weight and abnormal bud was not significant. Germination rate as important 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 dry matter (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 germination parameters.
