Catharanthus roseus (L.) G. Don is well known medicinally important plant. Alkaloids derived from this plant are used in the treatment of cancer. Triacontanol (TRIA) proved as a potent plant growth regulator in agriculture. We have investigated the role of TRIA in enhancing the growth and physiological attributes of C. roseus. Therefore, an experiment was conducted to evaluate effect of TRIA on plant growth and physiological activities at 120 and 150 days after planting in earthen pots. Four concentrations of TRIA viz. 10-0 (Control) 10-7, 10-6 and 10-5 M were applied through leaf spraying. Foliar application of TRIA at a concentration of 10-6 M caused a significant increase in plant growth and physiological parameters as compared to the control (10-0 M).
