ROLE OF PLANT GROWTH REGULATORS ON IN VITRO CULTURES OF PTEROCARPUS MARSUPIUM (ROXB.)

Plant growth regulators (PGR’s) play an essential role in determining the development pathway of plant cells and tissues in culture medium. The auxins and cytokinins are most commonly used plant growth regulators. Plant growth regulators (PGR) are vital for plant developmental process. Pterocarpus marsupium is known as Indian Kino Tree or Malabar Tree, which is exploited due to its medicinal properties such as anti bacterial, anti diabetics, anti analgesic etc. The objective of this research is to study the effect of different growth hormones on Pterocarpus marsupium to further standardize the in vitro miropropagation protocol. The result of the study conducted showed that cytokinine with low concentration of auxin has optimal for shoot multiplication and maintenance of in vitro cultures of Pterocarpus marsupium.
