Freshly harvested, fully mature green guava fruits of cv. Khaza (Local) were subjected to different post harvest treatments viz.,6N- Benzyl adenine (BA) 50 ppm (T1), Gibberellic acid (GA3) 50 ppm (T2), Carnauba wax (CW) 1% (T3), BA 50 ppm + CW1% (T4), GA3 50 ppm + CW1% (T5)  and Control (T6) with 4 replications in Factorial CRD design and stored in ambient condition (Temp: minimum 180C , maximum  240C, and RH: 57-84%).Observations were recorded on physiological loss of weight (PLW %), fruit firmness (Kg/cm2), TSS (Brix), titratable acidity (%), ascorbic acid (mg/100g), organoleptic quality and fruit marketability. The results indicated that PLW in carnauba wax treatments with or without growth substances remained low throughout the period of storage. Treatment of fruits with benzyl adenine and carnauba wax (BA+CW)  i.e., T4 exhibited least PLW and retained  higher firmness, TSS, acidity, ascorbic acid, marketability and organoleptic quality during storage compared to other treatment, this was followed by T5 (GA3+CW) and T3 (CW). In general, firmness and ascorbic acid continuously decreased during storage while TSS, acidity and organoleptic quality increased up to 3rd day of storage; there after it steadily decreased during subsequent period of storage. Organoleptic rating revealed superiority of T4 and T5 over other treatments while the control fruits were undesirable on 9th day.

Key words: Guava, Carnauba Wax, Growth Substances, physico-chemical changes, marketability and Storage.
