Abstract
Abstract Buds of standard chrysanthemums (Chrysanthemum morifolium Ramat cvs. Albatross and Fred Shoesmith) from 5 to 12 cm in diameter were cut with 60 cm stems and stored at low temperatures (−0.5 to 1.5°C) for up to 5 weeks. Flower buds were opened in sucrose solutions containing 25 ppm silver nitrate and 75 ppm citric acid. Small size buds developed flat heads when stored over 2 weeks; the disc florets failed to develop fully. Leaves which are normally free of necrosis when opened in sugar solutions developed desiccation injury after long storage. The flat shape of the inflorescence can be prevented by storing large buds (10-12 cm); however, botrytis becomes a major problem on the exposed ray florets.
