Abstract
Mechanical methods in propagation are the methods or techniques which improve the physiological and biological parameters of the fruits. Ringing and girdling break the downward translocation of hormones, carbohydrates, and other possible root promoting substances which help in shoot initiation. The techniques like cincturing are also used for induction of flowers. The tree is scored at the start of flower initiation, basipetal transport of auxin will be disrupted, which will led to an increase in root-derived cytokinin. This root- derived cytokinin should stimulate cell division in the developing reproduction bud, thereby raising the metabolic activity of the bud. Notching is also a mechanical technique which is done to increase the growth of lateral shoots, but to be effective it had to be done at bud break or soon thereafter.
