EFFECT OF HIGH TEMPERATURE ON BUD BLAST IN ASIATIC HYBRID LILY |
| Author: | Mark S. Roh |
| Abstract:
Asiatic hybrid lily (Lilium elegans) 'Red Carpet', 'Cherub', 'Sunray', and 'Connecticut Lemonglow' were forced on August 2, 1984 from frozen bulbs. Bulbs were potted and then placed in growth chambers at day/night temperatures of 16°/13°C or 26°/24°C for 14 days. Flowering was accelerated and the number of blasted primary buds was highest in 'Red Carpet' and 'Cherub' at 26°/24°C. The number of aborted tertiary buds was highest in 'Connecticut Lemonglow'. The content of ethanol soluble fructose, glucose, and sucrose in leaves and buds was lower at 26°/24° than at 16°/13° in 'Red Carpet'. The supply of available carbohydrates to developing buds may be limited at high temperatures and this may cause flower buds to blast. Forcing Asiatic hybrid lilies at high temperature before shoot emergence should be avoided to produce high quality plants. | |
