Abstract :
The mango (Mangifera indica L.) is a
climacteric fruit and manifests high postharvest losses
due to its high perishable nature and requires special
postharvest treatments to extend its shelf life. The study
was undertaken to determine the effect of 1-
methylcyclopropene (1-MCP) concentration, packaging
material, storage temperature and time on the
postharvest quality attributes of two mango cultivars
namely Broken and Dausha grown in Gboko, Benue
State, Nigeria. The fruits were harvested at green-mature
stage and were treated with 1-methylcyclopropene (1-
MCP) (0, 1000, 3000 and 5000 ppb) in closed air tight
plastic containers for 24 h. The fruit samples were
divided into two, one part was packaged in paperboard
and another part unpackaged. The samples were stored
for 90 d at 11, 13, 15 and 29 oC (ambient) respectively.
Treatments were laid out in factorial arrangement in
randomized complete design (RCD) with three
replications. The results showed that decay/chilling
injury, colour change, firmness, total carotenoids (TC),
vitamin C, pH, titratable acidity (TTA), total soluble
solids (TSS) and TSS/TTA ratio were significantly
(p˂0.05) affected by 1-MCP treatment, paperboard
packaging, storage temperature and cultivar throughout
the storage period. The 1-MCP treated and packaged
fruits showed better performance, retaining quality in all
physiological ripening parameters as well as reduced
senescence up to 90 d at the lowest storage temperature of
11 oC and highest 1-MCP concentration of 5000 ppb. The
untreated and unpackaged fruits on the other hand
stored only for 15 d at all the temperatures studied. In
terms of variety performance, Dausha mangoes recorded
low fruit decay and maintained remarkable quality up to
the end of 90 d in packaged paperboard at 11 oC while
Broken stored for 75 d under the same conditions. The
research findings show great potential of reducing
postharvest loss of Dausha and Broken mango cultivars
in Benue State thereby boosting the economy of mango
farmers in the State.
