Effects of Preharvest Temperature and Light Vaselife of Lilies
Light and temperature may affect postharvest vaselife of cut flowers through altered sugar levels. Evidence includes changes in vase life due to growing season and to different production areas. As temperature increases, carbohydrate use in growing plants increases faster than total carbohydrate production. Also, carbohydrate production decreases as light levels decrease, while carbohydrate use remains steady. This study evaluates the effect of light and temperature during production on the vaselife of cut lilies ‘Vermeer’ and ‘Dazzle’ and sunflower ‘Sunbright’.
