Studies on the micropropagation of Easter lily 'Lilium longiflorum Thunb' bulbs I-establishment.

摘要

On taking explants from field grown lily plants, no growth response was detected for any of the bulb explants and they eventually died. On the contrary, scales of the aerial bulbils grown on the flowering stem, survived and positively responded exhibiting growth and proliferation. Only the basal part of the in vitro grown leaf explants survived excision and after inoculation on MS medium showed a positive response by growth and proliferation. Strength of MS medium did not significantly affect shoot number/explant. On the contrary, shoot weight was significantly increased as the medium strength increased. Using MS medium at 3/4 and full strength gave the significantly longest shoots, the highest leaf number and the highest total chlorophyll content of shoots. The full strength MS resulted in the heaviest shoots.
