Advantages of Cutting –

In this method rooting is induced after detaching parts from mother plant, so it is very necessary to have live cells of stem, leaf or roots up to rooting. For this purpose cuttings should be kept in proper environmental conditions. 1) This type of propagation does not require the special technique as like budding or grafting. 2) There is no problem of incompatibility with root stock which is always shown in budding and grafting. 3) In a little period of time we can get more than one feet high plant. 4) The genetical characteristics of plants propagated by cutting are true to type . Limitations of Cutting – 1) Certain fruit plants have difficulty in rooting. 2) Possibility of mutation. 3) Success differs largely according to plant species and season.
