Abstract:
A study was carried out at horticulture laboratory of Gokuleshwor Agriculture and Animal
Science Collage, Gokuleshwor Baitadi, Nepal during June 19 to July 01, 2018 to evaluate the
effects of different ethylene doses and biological ripening agents on quality and self-life of
banana. This research was conducted on Complete Randomized Design (CRD) with five
treatments and four replications. The treatments consisted of five different ripening agents i.e. T1
= Control, T2 = Biological ripening agent (equal proportion of ripe banana + ripe apple + asuro),
T3 = 250 ppm ethophon, T4 = 500 ppm ethophon and T5 = 750 ppm ethophon. In experiment, ten
banana fingers were used as destructive sample and six fingers were used as non- destructive
method of sampling. The research result showed that the maximum TSS (270 Brix) and TA
(0.936%) was found in T3 (250 ppm ethephon) and minimum TSS (13.0 0Brix) and TA (0.488%)
was observed in in T1 (control). Likewise, the highest pH (6.22) was found in T1 (control) and
least (4.27) was observed in T5 (750 ppm ethophon). Also, minimum physiological loss in
weight (22.23%) was observed in T2 (Equal proportion of ripe banana + ripe apple + asuro) and
maximum (32.53%). in T5 (750 ppm ethophon). Similarly, maximum firmness (10.70 Kg/cm2
)
was observed in T2 (Equal proportion of ripe banana + ripe apple + asuro) and minimum
firmness (9.51 Kg/cm 2
) was observed in T5 (750 ppm ethophon). This study suggest that, for
effective ripening of banana T3 (250 ppm ethophon) respond best result and for increasing the
self-life of banana T2 (Equal proportion of ripe banana + ripe apple + asuro) was found best
biological agent. |
