FLOWER QUALITY IN RELATION TO STORAGE TREATMENTS FOR EARLY FORCING OF NARCISSUS AND TULIP

E.D. Turquand
Narcissus bulbs lifted early, before the end of June, and immediately stored at 35°C for 5 days, produced better quality flowers with shorter stems than bulbs stored at 17°C from lifting. Later lifting improved flower quality and size but flowering was later. Cool storage for longer than 6 weeks and below 9°C reduced flower quality.

Reactions of tulip cultivars to storage treatments varied. When compared with storage at 20°C, 34°C for 7 days after early lifting forwarded flowering and reduced stem length and flower size of cv. 'Paul Richter', but improved flower quality of cv. 'Apeldoorn'. Cool storage below 9°C increased the stem length but reduced the flower size of some cultivars.

Keeping quality of the narcissus and tulip flowers was not affected by any warm and cool storage treatments, but forcing later in the season improved vase life.
