摘要

Pruning is a critical horticultural practice that significantly influences the vegetative growth, reproductive efficiency, and fruit quality of various fruit crops. This study evaluated the impact of different pruning intervals on the growth, yield, and fruit quality of ‘Thai Apple Ber’ (Ziziphus mauritiana Lam.) under Punjab agroclimatic conditions. Pruning treatments were applied at 15-day intervals from 20 February to 20 May during the 2023–2024 season across two locations. The results showed that early pruning (20 February) significantly improved vegetative growth, including plant height, canopy spread, and canopy volume by promoting better light penetration and resource allocation. Furthermore, early pruning (5 March) improved key pomological traits, including fruit diameter and fruit weight, alongside favorable biochemical attributes such as higher total soluble solids, total sugars, reducing sugars, ascorbic acid content, moisture content, ash content, crude fiber, and DPPH content. We conclude that early pruning (5 March) is crucial for enhancing pomological traits and biochemical attributes of ‘Thai Apple Ber,’ providing guidance for optimized orchard management and improved productivity and profitability under Punjab conditions.
