In vitro multiple shoot regeneration of Solanum nigrum L., an Indian medicinal plant was accomplished on MS medium utilizing shoot tip and nodal explants. Direct multiple shoots differentiated within 6 weeks when explants were cultured on MS medium containing BAP (1.0-5.0 mg/l) and KIN (1.0-5.0 mg/l) individually. Among various concentrations of cytokinins tested, maximum number of multiple sho...

An improved micropropagation protocol was developed for Zingiber moran and Z. zerumbet, two wild species of the genus Zingiber, found in Northeast India. The effects of growth regulators, sugar concentrations, and nutrients were tested on the rate of shoot initiation and multiplication. An increase in proliferation and multiplication occurred in modified Murashige and Skoog (MS) medium suppleme...

The promotive effect of AgNO3 and aminoethoxyvinylglycine (AVG) on in vitro shoot regeneration from cotyledons of Brasska campestris ssp. peklnensls in relation to endogenous 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, ACC, and ethylene production was investigated. AgNO3 enhanced ACC synthase activity and ACC accumulation, which reached a maximum after 3 to 7 days of culture. ACC accu...

Until now numbers of efforts have been made to deduce the optimized conditions for the in vitro regeneration of tomato plant. The optimized conditions deduced are contradictory to each other and to validate the optimum conditions the present investigation was carried out which directs the use of 1.5 mg/l IAA + 1.5 mg/l Zeatin with full strength Murashige and Skoog’s (MS) medium for the developm...

The gerbera market would benefit from an efficient and simple protocol for high rate regeneration for propagation and genetic engineering. With these objectives, this investigation was done on shoot regeneration via direct organogenesis from leafy petiole explants of Gerbera jamesonii ‘Royal Soft Pink’. Murashige and Skoog (1962) (MS) medium was supplemented with 0.1 mg L-1 indole-3-acetic acid...

In vitro propagation of C. morifolium cv. ‘Homa’ and cv. ‘Delkash’ and wild C. coccineum via direct and indirect organogenesis and somatic embryogenesis were investigated. BAP at 0, 1, 2 and 3 mg l-1 or NAA at 0, 0.05, 0.1 and 0.2 mg l-1 concentrations were used to induce direct and indirect organogenesis of shoot tip explants. To study the callu...
