Chlorophyll fluorescence as an indicator of physiological changes in cold-stored broccoli after transfer to room temperature
1999
DeEll, J.R. | Toivonen, P.M.A.
Our objective was to determine if chlorophyll fluorescence could be used as an indicator of physiological changes in cold-stored broccoli after transfer to room temperature. Mass loss, respiration, and ammonia content increased when the broccoli were held at 18 degrees C for 72 h, whereas the chlorophyll fluorescence measurements (Fv/Fm, T1/2 and Fmd) decreased. Broccoli color began to change after 24 h, as hue decreased rapidly and chroma increased. Fv/Fm decreased markedly only after the first 24 h when the color changes began, whereas T1/2 and Fmd decreased continuously as the broccoli aged. Both T1/2 and Fmd correlated negatively with mass loss and respiration.
