Abstract
In order to find out the feasibility of producing grafted red pepper (Capsicum annuum L.) seedlings with root-removed rootstocks, rooting response and subsequent seedling growth was also evaluated. Pinching the top of pepper seedlings for cutting significantly reduced the rooting of cuttings in 10 commercial hot pepper cultivars. Normal rooting was obtained from all commercial cultivars even though the rooting response varied considerably among cultivars. Poor rooting was observed in 'Gukbo' and 'Chungyang'. Rootone treatment significantly promoted rooting in all tested cultivars and the decrease of rooting response caused by pinching could be fully recovered by rootone treatment. Among the ten commercial rootstocks developed for hot pepper grafting, 'Tantan' showed the best rooting response followed by 'Konesian Hot' and 'Wonkwang 1'. Most of these rootstocks, however, showed higher rooting response as compared to the popular commercial cultivars, 'Manit', 'Chungyang', and 'Nokkwang'. Pasting of IBA at cut surface promoted the rooting of pepper cuttings, but the effect was not quite pronounced as compared to rootone treatment.
