In vitro bulblet productivity in different explants of hybrid lilies

Lilium is one of the most important floriculture crops and is in great demand as cut flower and potted plant. Different explants have been used to regenerate lilies in vitro. In the preliminary experiment different levels of NAA and BA were used to examine their effect on bulblet regeneration, average number and fresh weight of bulblets. The most effective treatment; 2 mg 1 -1 NAA and 1.5 mg 1 -1 BA was selected to compare bulblet productivity in different explants in the five hybrid lily cultivars. The bulblet formation was highest (78.64%) in the bulbscale explants. Average number of 3.1 bulblets per an explant was recorded in root explants followed by node, bulbscale, leaf and internode. Bulblets formed in the bulbscale explants were the largest with an average fresh weight of 350.6 mg. The cultivar 'Beartix' produced the greatest number and the largest bulblets in the explants of node. The bulblets stored at 2°C for 30 days in cocopeat survived with 80-82% success.
