| Abstract:
The rapid respiration and growth of tuberose inflorescences indicate the importance of temperature management and carbohydrate supply to long vase life. Under normal display conditions, many buds aborted, probably because of carbohydrate stress. A sugar-containing vase preservative (1.5%) and/or pre-treatment with sugar (20% sucrose for 15–20 hours) improved display life of the stems before or after storage. There was a very high correlation between vase life and stem size. The presence of open flowers on the spike increased solution uptake and the response to the sucrose pulse. Tuberose florets produced very little ethylene, and were not affected by exposure to ethylene. | |
