Abstract: An investigation was carried out during 2015- 2016 at Department of Fruit crops, HC & RI, Coimbatore to find out the biochemical properties and biotic stress inhibiting enzymes activities of papaya seedlings and intervarietal grafts. The experiment was laid out in RBD with four replications. Total chlorophyll content was maximum in TNAU Papaya Co.8 seedling (1.92 ± 0.008 mg g-1) and minimum in Co.7 seedling (1.52 ± 0.010 mg g-1 respectively). Higher soluble protein content was found in Carica papaya (Co.7) grafted on Carica papaya (TNAU Papaya Co.8) (14.67 mg g-1). The total phenolic content was found to be higher in T1 (2.10 mg g-1) and found to be lower in T4 (1.44 mg g-1). Among the treatments, the peroxidase activity was found to be higher in T4 (0.40 ± 0.006 min-1g-1) and found to be lower in T2 (0.34 ± 0.002 min-1g-1). The PAL activity was recorded higher (0.44 μ min g -1) in TNAU Papaya Co.8 (T1) while T2 and T4 recorded lower PAL activity (0.41 μ min g -1).
