Translocation of dormancy and maturity factors which are located in certain parts of scales was studied in shoots from non-vernalized and vernalized double nose bulb of Lilium longiflorum Thunb. cv. Nellie White.
Dormancy factor, related to the speed of shoot emergence, was not translocated through the basal plate. A similar level of dormancy appears to be present in both mother and daughter scales of late harvested bulbs. Although the cavity in the basal plate was formed during the bulb vernalization treatment, maturity factor, determined by the acceleration of flowering responded to the vernalization treatment, was translocated provided bulbs had received a vernalization treatment in order that the promotive substance could be synthesized.
Maturity factor determined by the number of flower buds and also by plant height was not completely translocated through the basal plate.
We suggest that the maturity, which is independent to the dormancy, must be evaluated by the number of flower buds and leaves, and plant height, besides the flowering acceleration response by the bulb vernalization treatment in the L. longiflorum bulb.
