A protocol for fast in vitro propagation of Impatiens hawkeri cv. Sweeties Blue Star, an important ornamental-cover species

Abstract Impatiens hawkeri is among the three important bedding plants in world. There no efficient protocol for fast micropropagation of cv. Sweeties Blue Star. Single nodes were germinated on Murashige and Skoog (MS) medium supplemented with 1-naphthaleneacetic acid (NAA; 0.00, 0.10 0.50 mg l-1), 6-benzyladenine (BA; 0.10, 1.00 l-1) kinetin (KIN; l-1). The shoot length was highest containing l-1 NAA control. largest number shoots (14.06 14.00 per explant) produced media BA, NAA, respectively. along BA found to be superior production leaf (57.13). Maximum root (33.80 mm) (29.13) obtained without KIN. Plantlets transplanted pots filled perlite peat moss (in ratio 1:1) transferred greenhouse acclimatization. Regenerated plantlets morphologically identical mother plants. Upon ex vitro transfer, 100% survived.
