Fate of biochemical components of Catharanthus roseus after treatment with different plant growth regulators

The effect of different plat growth regulators like paclobutrazol (PBZ) gibberellic acid and Pseudomonas fluorescens treatments on the biochemical components of Catharanthus roseus was investigated in the present study. The treatments were given to plants by soil drenching on 38, 53, 68 and 83 DAP. The plants were taken randomly on 45, 60, 75 and 90 DAP and separated into root, stem and leaves and used for determining biochemicals. Proline, aminoacid and glycine betaine were extracted and assayed from both control and treated plants. It was found that plant growth regulators have a profound effect on the biochemicals and caused an enhancement in Catharanthus roseus. Our results have good significance, as this alters the biochemical status of this medicinal plant, as this plant being an essential component of traditional as well as modern pharmaceutical systems.
