Studies on the Effect of Auxin and Season on Rooting Stem Cuttings of some Important Shrubs in Nursery Beds

Abstract

This paper describes the results of experiments on rooting of stem cuttings of Debregeasia hypoleuca, Coriaria nepalensis, Woodfordia floribunda and Berberis lycium as affected by season and auxin application. 100 mgl^-2 IBA and 100 mgl^-1 NAA gave maximum rooting in D. hypoleuca and W floribunda respectively during spring whereas, 100 mg^-1; IBA resulted in better rooting of C. nepalensis during rains. Rooting of C. nepalensis was enhanced when cuttings were dipped in 0.5 per cent IBA-AC during rainy season. B lycium failed to initiate roots irrespective of season and auxin application.
