The search for techniques that extend shelf life of guava (Psidium guajava) fruits, and
reduce its postharvest losses is desirable. The objective of this work was to evaluate the
effects of concentrations of competitive ethylene antagonist calcium salts on conservation
of'Sardar" guava fruits. Treatments consisted of 0.5%, 1% Calcium Nitrate, 1%, 2% Calcium
Chloride and 0.5%, 1% Calcium Sulphate for 12 days followed by storage at room
temperature. The application of 1% calcium chloride for 12 days was efficient in delaying …
