| Abstract:
Scaly rhizome formation in Achimenes cv. Primadonna was investigated under controlled conditions in growth chambers. When plants from seeds were grown at 30-25°C (day/night), scaly rhizome formation was delayed. Plants from cuttings grown at 30-25°C showed a delay in scaly rhizome formation. Also, in plants grown from rhizomes, the number of scaly rhizomes and fresh weight of scaly rhizome were lowest at 30-25°C. These results indicate that high temperature at 30-25°C retards the scaly rhizome formation in Achimenes. | |
