cytokinin, potassium and calcium on yield and shelf life of banana (Musa AAB
Nendran) fruits" were carried out in the Department of Pomology and
Floriculture, College of Horticulture, Vellanikkara. The study was investigated
during two seasons from 1997 to 1999 with the objective of increasing the yield
and shelf life by bunch management sprays in plants which had been given
bunch stalk feeding of urea, primarily by use of a nutrient viz., potassium;
secondly by use of a nutrient which acts in preserving the integrity of the cell
wall viz., calcium and thirdly, a plant growth regulator with known anti-
senescence properties viz., cytokinin.
The study emphasized the overall superiority ofMpercent.K2S04
sprays applied at third and fourth week after bunch emergence. Yield and yield
components like the finger characters such as length, grade and FCr were
improved by the treatments. A delay in maturity and ripening and an extended
shelf life were observed.
The quality of treated fruits revealed reduced acidity, increased
sugar contents, higher urease activity, lower residual urea and lower levels of
nitrite nitrogen. Electrolytic leakage was also less in K treated fruits.
Among the cytokinin treatments 50 mg l' of kinetin and 75 mg r'
of BA applied at third and fourth week after bunch emergence proved better.
Yield and yield parameters i.e., bunch weight and finger characters such as
length, grade and FCr were significantly improved by the bunch management
practises involving post- bunching sprays of cytokinin. The. kinetin sprays
delayed maturity and ripening besides, qualitatively improving the shelf life.
Calcium infiltration technique could reduce the percentage
reduction in finger weight significantly and qualitatively increase shelf life. Also
an increase in quality by way of reduction in acidity and increase in total soluble
solids, especially in calcium infiltration treatments was observed.
The electrolytic leakage of fruits was found to be less in calcium
infiltrated fruits and above all, the effective treatments were more acceptable in
terms of taste. The calcium content in the pulp and peel were increased due to
infiltration. Analysis of the calcium content in calcium treated fruits revealed that
calcium content was more in the peel than in the pulp. Sensory evaluation carried
out by a taste panel revealed that consumer acceptability of treated fruits was in
no way reduced.
