| Abstract: | Present study investigated the effects of IBA on Scaevola crassifolia rooting and relevant oxidases.The dynamics of activity of peroxidase(POD),super oxide dismutase(SOD),catalase(CAT),polyphenol oxidase(PPO) and indole acetic acid oxidase(IAAO) during rooting were studied with random block experiment.The results showed that rooting type of S.crassifolia was the phloem.When its cutting was treated by IBA at a suitable concentration,rooting rate and the quality of root system could be significantly enhanced.... |
