The increase in fresh and dry weights of roots may be due to exogenous application of auxin which generally stimulate the movement of natural auxin and other materials downward from the leaves and shoot tips and accumulate at the girdling zone resulted in root formation with higher fresh weight as reported by Maurya et al. (1998Bhagat et al. These wounds were covered with soil media containing (2016) in jackfruit. of the year i.e. This Chapter's Author Mrs Deumaya Rana Dahachaur-4, Surkhet.
