THE EFFECT OF STORAGE TEMPERATURE FLUCTUATIONS ON THE POST-HARVEST PERFORMANCE OF ROSA HYBRID L. 'DUETT'
The most fundamental factor in maintaining quality during transport and extending storage after harvest is temperature. The flowers, in this trial, were subjected to a sequence of temperature fluctuation during storage to simulate transport and pack house handling conditions. Rosa hybrid L. Duett was stored at 2°C and fluctuated between 2 and 15°C for 10 days on a two day cycle. Temperature fluctuation had a major impact on the respiration rate and vase life of the flowers. The quality of the flowers under the temperature fluctuation was severely affected as indicated by weight loss, wilting, tissue browning and short vase life. The trial demonstrated that exposing Duett to fluctuating has a negative effect. This results in a reduction of vase life which was influenced by the stress the flowers experienced and the disease level. Fluctuating temperature also encouraged the incidence of Botrytis cineria on the flowers. It is clear that temperature fluctuation in flowers can compromise quality and therefore temperature fluctuations in the handling chain and storage should be addressed to improve quality.
