Effect of Different Factors on the Success of Tender Shoot Cleft Grafting in Chilgoza (Pinus gerardiana Wall)

Four factors, namely time of grafting, age of clone, age of ischolar_main-stock, and age of scion, have direct bearing on the success of tender-shoot-cleft-grafting on Chilgoza. February is the best period which gives 65-70% success, followed by medium-size of tree (less than one metre girth), two and half years old ischolar_main-stock and two years old scion.
