Effect of geographical orientation (aspect) of ‘Apple’ mango on russeting. Fruits were sampled from north-, south-, east-, and west-facing sides of the canopy. The tree rows were aligned perpendicularly to the slope and N, S, E, and W positions. Russeting was quantified using a five-score rating scheme. Score 0: 0% of the fruit surface area russeted; score 1: 1–10% russeted area; score 2: 11–25% russeted area; score 3: 26–50% russeted area; and score 4: 51–100% russeted area.

z Main effect of site was significant but neither aspect of fruit nor interaction were significant by analysis of variance significant at p ≤ 0.05. Mean separation according to the Tukey studentised range test, p ≤ 0.05. The number of replicates was 264.
