Figure 1From: Solar ultraviolet radiation is necessary to enhance grapevine fruit ripening transcriptional and phenolic responsesRadiation received by plants under each treatment. Left, spectral irradiances measured in the three treatments used: no filter (Ambient), UV-transmitting filter (FUV+), and UV-blocking filter (FUV-). Right, daily doses of biologically effective UV radiation (UVBE) received by the plants during the experiment (7 June to 7 September 2012) in the three treatments.Back to article page
