Abstract

Dormancy development in four Lilium genotypes, L. speciosum, Star Gazer, C. King and Snow Queen regenerated in vitro was compared. Major factors influencing dormancy development were the same for different genotypes and especially L. speciosum and Star Gazer, that are closely related, reacted similarly. Temperature was the main factor in dormancy induction and breaking. The range of temperatures that induced dormancy and the level of dormancy that developed differed per genotype. In Star Gazer, dormancy developed gradually but in Snow Queen, dormancy developed very fast. The reactions to temperature, reflected the climate in the area of origin. Abscisic acid deepened the level of dormancy induced by temperature but had no effect under non-inductive temperature conditions. When abscisic acid synthesis was blocked,no dormancy developed. Dormancy in all genotypes was broken by cold incubation for several weeks. The cold requirement of the genotypes differed in line with the natural winter conditions in their habitat. The effect of hormones on dormancy breaking was also investigated. A gibberellin treatment of24 h broke dormancy in L. speciosum, Star Gazer and Snow Queen.
