Abstract

This study evaluated the drying efficiency of green and purple basil (Ocimum basilicum L.) varieties at three phenological stages (two weeks before flowering, one week before flowering, and at flowering) under Niğde ecological conditions, incorporating Mycorrhiza and Trichoderma treatments to assess their impact on leaf water loss and overall drying performance. Plants were grown in peat-filled pots, and 1 cm² leaf discs were oven-dried at 80℃ for 48 h. The drying ratio (%) was determined by dividing the dry weight of the leaf samples by their fresh weight and then multiplying the result by 100, and data were analyzed using ANOVA and LSD tests (p ≤ 0.05). Results revealed that drying efficiency peaked at the flowering stage in both varieties. The highest drying ratio was recorded in purple basil at flowering under control conditions (54.7%), significantly higher than green basil (p ≤ 0.05). Purple basil also showed a high drying ratio two weeks before flowering (43.5%) in control treatment. Green basil consistently exhibited lower drying ratios, with its highest value under Trichoderma at the earliest stage (26.1%). Mycorrhiza and Trichoderma treatments reduced drying ratios in purple basil but had minimal effect on green basil, indicating varietal differences in treatment responsiveness. At one week before flowering, drying ratios ranged from 22.0% to 31.2% with no significant differences. These findings suggest that purple basil is more suitable for drying-focused processing, particularly when harvested at flowering without biological treatments. For freshness preservation, applying Mycorrhiza or Trichoderma can reduce water loss in purple basil. In contrast, green basil shows more stable but lower drying efficiency across treatments. Overall, integrating growth stage, variety, and microbial treatments is essential for optimizing basil postharvest quality and drying strategies under semi-arid ecological conditions.
