Abstract: | An efficient protocol was developed for regeneration of healthy plant derived from six categories of explants from both in vivo and in vitro raised plants, viz. roots, corm buds (dormant and nondormant), young leaves, stems, pedicels, and shoot tips from aerial shoots. MS medium supplemented with various concentrations and combinations of auxin, cytokinin, and organic acids was used. 98% of callus induction occurred in nondormant corm bud explants. The greatest number of multiple shoots (57) was observed in corm-derived calluses. Vigorous root formation occurred in all cases when multiple shoots were derived. Histomorphogenetic studies revealed that not only the origin of shoot and root buds in in vitro systems, but the morphology and structure of leaves resemble those of in vivo plants too. |
