Fig. 1From: Mass spectrometry-based metabolomics study for delay tomato fruit ripening by sound wavesDelayed ripening of tomatoes mediated by sound-wave treatment at 1 kHz. The morphological changes in ripening are shown with respect to the color of the tomatoes at A 0, B 7, C 10, and D 14 d after harvest. E Proportion of green tomato fruits during the 14 d following sound-wave treatment (1 kHz). Non, control; Sound, sound-wave treatmentBack to article page
