Marvel II – Trials Conclusions • Possible to sell African Marigold flowering earlier in Long Day conditions, by using limited Short Day during plug stage. • 10 hours SD made flowering about 2 weeks earlier than 0 SD when forced under LD for all varieties, except Marvel II Yellow, that may require longer period of SD induction. • Recommend using 128 size plug trays instead of 288, to allow total 4 weeks of plug time. • Recommend 14 days of SD treatment to avoid incomplete flower induction.
