Abstract

Pot-grown ‘Angie Physic’ hibiscus (Hibiscus rosa-sinensis L.) plants at the tight bud and blooming stages were stored in darkness for 3, 6, or 9 days at 4.5, 10.0, 15.5, 21.0, 26.5, or 32.0C, and then placed in a greenhouse for 21 days. Plants showed the least amount of damage at 10.0 or 15.5C or when stored for 3 days. Plants stored at 10.0 or 15.5C had delayed flowering, larger and more flowers, less flower bud and leaf abscission, and a higher plant quality. Storage for 6 or 9 days resulted in plants with smaller and fewer flowers, greater bud and leaf abscission, less fresh weight, and a lower quality.
