Abstract:
Colour development is one of the important ripening processes for determining the quality of mango fruits. In this experiment, pre-harvest treated ‘Alphonso’ mango fruits were measured objectively for peel and pulp colour using Hunter (
L* a* b*) colour system. Azoxystrobin at 0.1% treatment resulted in brighter and superior reddish yellow colour development of peel of mango. Peel values of fruits under this treatment for
L* (63.38),
a* (17.66)
b* (61.03),
C* (62.13) and
h0 (70.48) were significantly higher than control and other treatments. Mango fruits under the same treatment achieved greater colour development for the pulp with
L* (64.16),
a* (28.43)
b* (66.34),
C* (75.18) and
h0 (68.54) that were in significance with rest of the treatments. Control fruits on the other hand showed poor values for each of colour coordinates indicating lack of proper colour development during ripening.
