Optimal Bulb Storage and Production Methods for Successful Forcing of Cut Pineapple Lily

Pineapple lily (Eucomis hybrids) has long, striking inflorescences that work well as a cut flower, but information is needed on proper production methods and postharvest handling protocols. The objective of this study was to determine the effects of bulb storage temperature and duration, production environment, planting density, and forcing temperatures on cut flower production of ?Coral?, ?Cream?, ?Lavender?, and

Pineapple lily (Eucomis hybrids) has long, striking inflorescences that work well as a cut flower, but information is needed on proper production methods and postharvest handling protocols. The objective of this study was to determine the effects of bulb storage temperature and duration, production environment, planting density, and forcing temperatures on cut flower production of ?Coral?, ?Cream?, ?Lavender?, and ?Sparkling Burgundy? pineapple lily. Stem length was greater in the greenhouse than the field and at the low planting density. Plants in the field at the low planting density had the shortest stem length for ?Coral? and ?Cream?, but still produced marketable lengths of at least 30 cm. Planting density did not affect ?Lavender? and ?Sparkling Burgundy? stem length or number of marketable stems. The productivity (number of marketable stems per bulb) was affected only by planting density for ?Coral? and planting environment for ?Cream?. Differences in stem quality and productivity differed for each cultivar and planting density over the next two seasons. The productivity of ?Coral? increased significantly from year to year, while the productivity of ?Cream? only significantly increased between the first and second years. The low planting density resulted in slightly more stems per bulb for ?Coral? over the next two seasons. Emergence after bulb storage treatments was highest in treatments where the bulbs were not lifted from the substrate and were subsequently grown at 18?C. Bulbs grown in the warmest (18?C) production temperature flowered soonest and had shorter stem lengths. For earliest flowering, bulbs should be stored in substrate in cool temperatures of at least 13?C and forced at warm temperatures of at least 18?C. ?
