Abstract: An experiment with Benzyl Amino Purine (BAP) on gladiolus ‘Candyman’ was conducted in the research farm of the Division of Horticulture, ICAR Research Complex for NEH Region, Umiam, Meghalaya, during 2007-08. In the study, corms (5.5-6.0 cm diameter) were soaked with different concentration of BAP (25, 50, 75, 100 and 150 ppm) and in tap water as control for 24 hours before planting, replicated four times in RBD. Results revealed that significant reduction in plant height, leaves/shoot, length and breadth of 2nd pair leaves with the increase of concentration of BAP from 25 to 150 ppm. However, maximum number of shoots per plant (5.73) was found in corms treated with BAP (100 ppm). Corms soaked with BAP, irrespective of concentration, recorded delay in flowering, reduction in flower diameter, spike length, spike diameter, florets/spike and rachis length. Significantly more spikes/plant (1.45) was observed with the soaking of corms with BAP (25 and 50 ppm). Among the corm characters, significant reduction was recorded in corm weight, corm diameter, coremls/plant and propagation coefficient with corms treated with BAP. Interestingly, significantly increase in number of daughter corms/plant was recorded with BAP (from 25 to 150 ppm), being maximum (8.16) in BAP (150 ppm) over control (1.53). Corm soaking with BAP (25 ppm) produced highest number of contractile roots/plant (22.86) over control (8.33). Corm soaking with BAP @ 25 or 50 ppm before planting found best for rapid multiplication of gladiolus ‘Candyman’.
