| Abstract : The aim of this study is to elucidate the synergistic role of ascorbic (AsA) and salicylic acids (SA) through different timing of their supplying with auxin (IAA) in adventitious root formation of mung bean cuttings under controlled conditions . AsA concentrations that stimulates rooting response with healthy features were 50,100,200 ppm but the best rooting response occurred at 200 ppm , that raised the rooting response to 2.3 times compared to control .The best SA concentration recorderd at 10-6 M which developed significant increase in root number 17 root compared to control 10.4 root. Using Hoagland́s solution in half strength with AsA increased roots number and length in the cuttings that treated with AsA at 100 , 200 ppm compared to AsA alone whereas Hoagland΄s solution with SA has no significant affect . AsA didn΄t act synergistically with IAA , 5 10-4 M but the best rooting response required, supplying AsA after IAA (posttreatment).SA has a synergistic action with IAA when supplied after IAA (posttreatment) .The later case raised the root numbr to 80 root comparing to SA (17 root) or IAA (70 root ) when supplied as indivisual for both . Key words: Adventitious root formation Antioxidant defense mechanism, Ascorbic acid , Auxin , Mung bean , Salicylic acid and Synergism. | ||
