Abstract
Muskmelon ( Cucumis melo L.) is a high-value crop with significant nutritional and market appeal. Protected cultivation improves fruit quality and profitability, but the lack of parthenocarpic varieties limits yield under low pollination conditions. This study evaluated the potential of plant growth regulators (PGRs) to induce parthenocarpy in muskmelon variety ‘Kashi Madhu’ under greenhouse conditions. A mixture of β-naphthoxyacetic acid (10 µM), gibberellic acid (GA 3 290 µM), 24-epibrassinolide (0.2 µM), melatonin (10 µM), and putrescine hydrochloride (180 µM) was applied via lanolin wax to the pedicels on the day of anthesis. PGR-induced fruits were 8.2% heavier (1.05 kg) and had 39% lower seed weight (6.88 g) than hand-pollinated controls (11.25 g). The edible-to-non-edible ratio improved by 74% (11.81 vs. 6.77), while total phenolic content and antioxidant activity increased by 73% and 29%, respectively. Enzymatic browning indicators, including PPO and POD activities, were significantly reduced, enhancing visual quality. These results demonstrate that PGR-induced parthenocarpy can improve yield efficiency, fruit seedlessness, and postharvest quality in greenhouse muskmelon. Further refinement of PGR combinations could optimize cost-effectiveness and application efficiency.
