Evaluate the germination variables of barley lines and varieties in response to humic priming

Humic Priming is one of the simple techniques that improve seedling power and establishment and thus the efficiency of the plant. This experiment was performed in order to evaluate the effects of different treatments of humic on the germination elements and seedling growth of barley cultivars in laboratory and greenhouse of the research field in Ardabil University in 2012-13. The experiment was as factorial based on CRD in three replications. The first factor was priming and the second was included genotypes. Results showed that there was significant difference between the levels of priming in terms of all traits except dry weight of plumule at 1% level. There was also significant difference between the studied lines and varieties at 1% level apart from the plumule and root dry weight. This implies high genetic diversity among hybrids in order to select for desired traits. There was also no significant difference in terms the interaction of priming levels × hybrids. In general we can say that humic priming had a significant impact on root and shoot length and caused root and stem elongation. In terms of priming levels, the maximum length of plumule and radicle were respectively allocated to 10 hours humic priming and 10 hours hydro priming. The highest percentage of germination was allocated to 5 hours humic priming with an average of 80 percent and the lowest was zero hour distilled water with an average of 62 percent.
