Plant regeneration in Curcuma species and assessment of genetic stability of regenerated plants

open access: yesBiologia Plantarum, 2010
An efficient plant regeneration protocol was developed from rhizomes of two Curcuma species C. longa and C. amada. Response was highly dependent on the season, with above 69 % of culture developing adventitious shoots during spring. Greatest regeneration
