A Note on Field Grafting in Chir Pine

Syotematic field. grafting was carried out every month in Chir Pine (Pinus roxburghii Sarg) at New Forest, Dehra Dun from September, 1975 to june, 1976. One hundred per cent success in 'graft take' was obtained both in autoplastic and homeoplastic grafls made during the months of September, November and january. The grafts made daring the months of April, May and june failed completely. The grafts made during the months of October, Decetmber, February and March showed 60, 70, 65 and 55 percent suecess in homeoplaotic grafts and 55, 60, 60 and 50 per cent in autoplastic grafts. The knowledge gained from this trial on the best time of the year for grafting with this species it is expected that the work on establishment of seed orchard will get speeded up.
