The data revealed significant increase in rooting response of fresh cuttings treated with (0.0001% and 0.1%) concentrations of HNO3 solution, significant increase in rooting response of aged cuttings (for 3 days in d/H20) with (0.0001% and 0.01%) concentration of HNO3 solution and highly significant increase in rooting response of aged cuttings (for 3 days in HNO3 solution) with (0.0001%) concentration, while highly concentration (0.5%) revealed highly significant decrease in rooting response compared to control (d/H20). Quantitative estimation oflAA by spectrophotometric method as indicators for oxidative processes that occurrence during aging phenomenon verified a highly significant increase of IAA content in hypocotyles of fresh and aged cuttings in optimal concentration of HNO3.展开更多
