Abstract

A study was made on the vegetative parameters of Dendrobium cv. Sonia-17 during 1999-2000 in Green House. The planting material consisted of ex-vitro established, six months old tissue culture plantlets of Dendrobium cv. Sonia-17 involving forty two treatment combinations. It was found that NPK 30:10:10 at 0.2% concentration along with BA 200 ppm resulted in larger diameter of the pseudobulb (3.92 cm) and more number of internodes per pseudobulb (5.67).
