Abstract
Pre-harvest care and management of horticultural plants are crucial to achieve postharvest quality of fruits. Influence of a few pre-harvest factors on geometry of apple (Malus domestica Borkh.) was determined by a field sampling of 270 apples from three varieties (Golden Delicious, Red Crispy, Red Delicious) belonging to three tree age groups (1 – 3, 4 – 6, and 7 – 9 years old) and two fruit positions (sun side & shade side). Statistical analysis showed that geometric parameters including weight, length, width, arithmetic diameter, and geometric diameter were significantly (P = 0.001) varied due to the three–way interaction effect of variety, tree age, and fruit position. Whereas, fruit volume and thickness were significantly (P ≤ 0.001) influenced by variety and two–way interaction of the tree age and fruit position. The aspect ratio, sphericity, and solid density were significantly (P ≤ 0.001) affected by individual influence of three pre-harvest factors. Research results emphasized the careful pre-harvest tree management to harvest good quality of apple.
