Fig 4. Effect of seed inoculation and foliar spray of antagonistic rhizobacteria on (A) Polyphenol oxidase (PPO), (B) Peroxidase (PO), (C) Phenylalanine ammonia-lyase (PAL) and (D) Catalase (CAT) activities in rice grown in pots under net house conditions.
Foliar spray of antagonistic bacteria and clip inoculation of Xoo8 was carried out on 21st and 23rd day, respectively after sowing. The leaves samples were collected 48 hours after foliar spray on rice plants. Non-inoculated plants with and without pathogen, were used as infected and healthy controls, respectively. Means are an average of three replicates and bars indicate the standard deviation. Means followed by the same letter differ non-significantly at P = 0.05. HC: Healthy control, IC: infected control.
