| Abstract: | The effects of chitosan on physiological biochemisal characters of mulberry seeds germination and seedling by treated the seeds with different concentration of chitosan citriacid solution were studied.The results showed that chitosan solution in appropriate concentration could improve germinating percentage,germinating index and vigor index of mulberry seeds,stimulate growth of seedling.The rate of respiration of germinating seeds,the content of chlorophyll and the soluble protein were higher than control.The avtivities of peroxidase,nitrate reductase and amylase increased along with increase of chitonsan concentration. |
