In the present investigation, changes in individual alkaloid profiles were studied in Catharanthus roseus (L.) G. Don. plants under treatment with Pseudomonas fluorescens. The Pseudomonas fluorescens treatments were given by soil drenching on 38, 53, 68 and 83 days after planting (DAP) by soil drenching. The plants were taken randomly on 45, 60, 75 and 90 DAP and used for estimating individual alkaloids like Ajmalicine, Catharanthine, Tabersonine, Serpentine and Vindoline contents. It was found that, Pseudomonas fluorescens has a profound effect and it caused a significant enhancement in the production of individual alkaloids when compared to untreated control plants.
