Abstract

In order to reveal the rooting mechanism of Dalbergia odorifera.T.Chen, the rooting mechanism of Dendrocalamopsis mongolica was 4,600 mg / L NAA rooting (POD), polyphenol oxidase (PPO), superoxide dismutase (SOD), indole (SOD), indoxylate (SOD), indoxidase Acetic acid oxidase (IAAO) and other root-related enzyme activity changes. The results showed that the rooting type of callus was decreased by 600 mg / L NAA, and the rooting rate and rooting quality were obviously improved. The activity of PPO, SOD and IAAO increased gradually after cutting, reached the peak at the time of root formation, and then decreased gradually. The activity of PPO, SOD and IAAO increased gradually after cutting. The activity of POD enzyme increased gradually after cutting, reached the peak at the root formation stage, then gradually decreased, then gradually increased, reached another peak at the root elongation, and finally decreased gradually, showing a bimodal trend.
