Abstract

Sugar apple (Annona squamosa L.) belongs to family annonaceae, is an arid zone fruit grown in India. Being a climacteric fruit, it is highly perishable with very short shelf life of 1 to 2 days after ripening. Hence, it is a major drawback and challenge for farmers. An experiment was conducted during the month of October 2015-16 to analyse the effect of chemicals along with organic coatings on storability and quality attributes of sugar apple fruits. Fruits of Annona squamosa were harvested manually at physiological light green fully matured stage, washed by fresh water to remove dust particles. Subsequently, fruits were selected randomly as per requirement. Apply various recommended chemicals and hormones, each of two doses namely CaCl2 1 and 2%, NAA 50 and 100 ppm, GA3 50 and 100 ppm and KMnO4 0.01 and 0.05% along with organic coatings of Aloe vera gel 50 and 100%, Sago 5 and 10% and Paraffin wax 5 and 10%). Thus total treatments were 15 including control. After app
