ROLE OF OUTER SCALE IN TWIN-SCALE PROPAGATION OF HIPPEASTRUM HYBRIDUM AND COMPARISON OF BULBLET FORMATION FROM SINGLE- AND TWIN-SCALES

H. Okubo, C.W. Huang, S. Uemoto
Protuberance initiation occurred on the abaxial surface of the inner scale in twin-scale propagation of Hippeastrum hybridum. However, the vascular connection occurred between the protuberances and the outer scale. Bulblet formation from the protuberances and leaf development were affected by the thickness and length of the outer scale. Instead of protuberance initiation, protocorm-like bodies were regenerated from single-scales, and bulblets were formed from the protocorm-like bodies. There were morphological and physiological similarities of the protocorm-like bodies to the protocorms of orchids. Possibility for multiplication of this plant from the multiplied protocorm-like bodies were suggested.
