CHARACTERISTICS OF CYCLAMEN PERSICUM MILL. SEED GERMINATION

F. CORBINEAU, N. NEVEUR, D. CÔME
The effects of temperature, light, oxygen, storage conditions and gibberellic acid on seed germination of a diploid cultivar of Cyclamen persicum were studied. Germination did not occur at 5°C or above 20°C, and was optimal at 15°C in the dark. Continuous irradiation with white light was inhibitory, even at very low irradiances. Germination was inhibited in hypoxia, to a greater extent at 20°C than at 15°C. Immature seeds germinated poorly but germinability increased during seed maturation. A high level of germinability was maintained during dry storage for at least two years over a range of temperatures between -30°C and +20°C. Storage at temperatures above 0°C even improved germinability at 20°C.

GA3 at high concentration (10-3M) stimulated the germination and reduced the inhibitory effect of light at 15° and 20°C. Short treatment with GA3 was enough for improving germination; this stimulatory action was maintained also after seed drying and during storage.
