| Summary: | The irregularity of the color and the small size of the berries in the table grapes in the Sonoran Desert represent a challenge for their export. The effects of the application of bioregulators at veraison were evaluated on the size, weight, color and cuticle changes in the berry of table grape cv. “Flame Seedless”. 8 treatments: TEST (Testigo absoluto), ETH1 (Ethrel 100 mg L-1), ETH2 (Ethrel 250 mg L-1), AS (salicylic acid 100 mg L-1), MEL (melatonin 25 mg L-1) and the combination of ETH2+AS, ETH2+MEL and AS+MEL. A higher weight was obtained in the berries treated with MEL, ETH2+MEL and AS+MEL (4.75, 5.46 and 5.14 respectively), while the control weighed only 3.75 g; similar behavior was presented in the size of the berries in which they reached a superior caliber with the treatments with MEL and combinations. The highest color index (CIRG) was obtained in the berries treated with ETH with values greater than 2.0 while the other treatments were lower than this value, no treatment reached the optimal CIRG (4-5). In the cuticular parameters, no differences were observed (p ≤ 0.05), except for the epicuticular wax content, with a higher content in absolute control berries (0.64 mg cm-2). |
