The effect of canopy positions (upper, middle and lower) on quality of mandarin fruit
cv. ‘Shogun’ stored at 20°C and 10°Cwas investigated. The results showed that the canopy
positions influenced the appearance and peel colour which the peel of fruits from the upper part
had more yellow and chroma value than the fruits from middle and lower parts which the peel
had more green colour. The canopy positions had no influenced on the fruit pulp colour. The
fruits from the upper part had total soluble solids (TSS), antioxidant activity (AA), ascorbic
acid (AsA), total phenols (TP) and total flavonoids (TF) contents higher than the fruits from
middle and the lower parts whilst total acidity (TA) of the fruits from different canopy positions
was similar. During storage, most physicochemical quality attributes seemed constant, except
TA which decreased on day 7 and antioxidant activity of the fruits stored at 10 °C which
decreased on day 21. In conclusion, the canopy positions had influenced on ‘Shogun’ mandarin
fruit quality which the fruits from the upper part had quality higher than the fruits from middle
and lower parts.
