Effect of Different Media on In vitro Rooting in Different Cultivar of Lilium longiflorum Cv. Elite, Brunello, Cordelia

摘要

Lilium (Lilium longiflorum Thunb.) belongs to the family Liliaceae and is a native of Northern Hemisphere (up to South Canada and Siberia). Conventionally Lilium can easily be propagated by sexual and asexual methods of propagation but these prevalentmethods are not capable of meeting the increasing demand in domestic and global market. Generally, Lilium is propagated through bulbs but, limited number of bulbs per plant, long dormancy period of bulbs which again results into non-availability of planting material throughout the year. Keeping in view the above facts, the present study was undertaken with the following objective: “To standardize the cost effective protocol for micro propagation of lilium to produce disease free and true to type plants at a faster rate”.The present investigation was carried out in the Tissue Culture Laboratory of the Centre for Research and Application in Plant Tissue Culture. The experiment was laid out in a C.R.D. (Factorial) with three replications. In vitro raised bulblets were separated out and were transferred on to the root regeneration media. Different levels of NAA were used in MS media for the rooting of in vitro raised bulblets and percent rooting of plantlet is recorded.It was interesting to note that the media LR-3 (MS + NAA 1.0 mg/l) is most efficient for rooting in all type of cultivars. All the three cultivars used responded very poor on media LR-1 (MS basal).
