| Abstract:
To find out suitable age of seedlings, the best time for patch budding veneer grafting and their comparative success, five monthly sowings from May to September; budding/grafting from November to March and two methods of propagation viz. patch budding and veneer grafting were studied. In case of veneer grafting, both defoliated and undefoliated scions were tried. In addition, the comparative performance of patch budding and veneer grafting was studied in situ also, on one year old seedlings during rainy season. Percenatage success in both the cases (potted and in situ seedlings) was recorded after sprouting i.e. about two and half months after the operation. The results obtained from propagation trials indicate that pach budding gave better success (61%) than veener grafting (36%) in potted seedlings and the performance of 6 to 7 months old seedlings was found satisfactory. In the case of veneer grafting, undefoliated scions were found to be a complete failure and hence defoliation, about a week prior to grafting operation was found essential. However, the observations recorded in situ that veneer grafting gave as high as 92 per cent success as against 62 per cent in case of patch budding during rainy season. For large scale multiplication of promising clones, seeds should be sown in alkathene bags during September-October and patch budding operation should be undertaken during March (i.e on about 6 month old seedlings), so that the sprouted buddings could be planted just before the onset monsoon. For quick multiplication, budding is preferable over grafting since more number of buds can be than scions per unit area of clonal material. | |
