Effect of radiation treatments on berry ripening at harvest time. Berry density was determined by floatation in a NaCl solution series for each treatment: Orange, Ambient (no filter); Purple, UV-transmitting filter (FUV+); Green, UV-blocking filter. Berry TSS (ºBrix) on each density interval were measured by a refractometer and mean values are shown above the bars of the harvested intervals. Data are means from three blocks per treatment. Black bars represent SD. Berry density distribution differences between treatments were not significant for any berry density interval (P >0.05 in every two-way ANOVA).
