Macropropagation of Ban Oak - Quercus leucotrichophora Camus, Through Stem Cuttings

Ban Oak (Quercus leucotrichohora Camus), a principal forest tree species of North-West Himalayan forest eco-system, was used to investigate the effect of chemical treatment, season, donor plant and shoot position on ischolar_maining and primary ischolar_main number, and subsequent survival of the ischolar_mained cuttings. The per cent ischolar_maining and primary ischolar_main number improved markedly upon application of chemical treatment. maximum per cent ischolar_maining (35.25) was recorded in the rainy season planted seedling cuttings treated with chemical formulation of 0.8% IBA + 0.2% p-HBA + 5% sucrose + 5% captan. Irrespective of chemical treatment, season and position, seedling cuttings demonstrated significantly better per cent ischolar_maining and primary ischolar_main number than tree cuttings. Primary ischolar_main number were more in lower portion of the shoot cuttings, while per cent ischolar_maining was higher in cuttings collected from the upper portion of the shoot. The seedling cuttings collected from upper portion of the shoot during rainy season displayed better survival than others. From the present study, it can be concluded that for achieving maximum ischolar_maining and survival of the ischolar_mained propagules, the cuttings should be collected during rainy season from the upper portion of the seedling shoot and treated with chemical formulation of 0.8% IBA + 0.2% p-HBA + 5% Sucrose + 5% Captan.
