Abstract
The present study evaluated the effectiveness of preharvest
interventions in mitigating postharvest losses in table grapes (Vitis
vinifera L. cv. Thompson Seedless) through foliar application of four
treatments: T0 (Control), T1 (biostimulant elicitor-based
formulation), T2 (calcium salt), and T3 (combination of
biostimulant and calcium-based formulation). Treatments were applied at three
spray schedules: 2 days before harvest (2 DBH), 10 DBH, and a combination of 10
+ 2 DBH. Among the treatments, T1 significantly reduced berry
rotting compared to the control at both 2 DBH and 10 DBH schedules. T1
also effectively minimized rachis browning, maintaining rachis greenness up to
8 days after harvest (DAH). Application of T2 at 10 DBH
significantly decreased berry shattering, while T2 at 2 DBH resulted
in the greatest reduction in berry cracking. Furthermore, T1
consistently enhanced total soluble solids, with a notable increase observed
under the 2 DBH treatment. T1 also exhibited the greatest efficacy
in minimizing postharvest weight loss at 2 DBH. These findings highlight the
potential of Velabs's biostimulant and calcium-based formulations as effective
preharvest tools to reduce postharvest physiological disorders and quality
deterioration in Thompson Seedless grapes, particularly when applied closer to
harvest.
