Abstract
Chrysanthemum is a short-day plant that need short-day conditions for flowering. For off season production artificial short-day conditions were given for flower induction by covering with black cloth or plastic. Inside, the cover had high temperature and humidity, making insect or disease easy to spread.
For this reason, the cost for off-season production was high because of labor consuming and high
chemical usages. It would be better if we could develop some suitable varieties for each production season. In this study, 22 chrysanthemum genotypes were grown in 3 different light durations: 11 hours of light duration (short-day conditions), 13 hours of light duration (long-day conditions), and 24 hours
of light duration (long-day continuous 24 hours conditions) in both on-season and off-season. Under
11 hours conditions, all genotypes produced flower buds and developed to full bloom in both seasons.
In 13 hours of light duration, most of genotypes produced flower bud; genotypes 1, 2, 4, 5, 8, 10, 16, 22, 26, 31, 32, J, K, and KF could developed to full bloom under on-season whereas growing under
off-season found that; genotypes 1, 2, 4, 5, 8, 10, 15, 16, 17, 22, 26, 27, 31, 32, 33, 35, 37, J, and KF produced flower bud but only genotypes 16 and J able developed to full bloom. For 24 hours light
durations under on-season; genotypes 1, 16, 17, 26 and J produced flower buds but only genotype J could developed to full bloom, under off-season condition; genotypes 1, 2, 8, 10, 15, 16, 17 and 32 produced flowers bud but all of them developed to long day buds which unable to develop to full bloom.
