Summary
Chlorophyll fluorescence analysis by pulse-amplitude modulation measurements was performed to assess the extent of chilling injury in stored sweet basil leaves. Changes in three photosynthetic characteristics, in relation to visible chilling injury rating, were monitored in leaves following modification of their chilling susceptibility by varying storage temperature and duration in two basil cultivars, or by soil application of triazole. Basil leaves developed severe or moderate visible symptoms of chilling injury after 4 days storage at 4 or 8 deg C, respectively, but remained undamaged when stored at 12 deg C. Fluorescence, photochemical quenching coefficient do not seem to be correlated with chilling injury. Non photochemical quenching is positively correlated. Effect of triazole application is studied. Changes in non photochemical quenching may provide a suitable, rapid and non-destructive criterion for estimation of chilling damage in green tissues.
