Effect of Phytohormones on Seed Germination and Seedling Growth of Coriandrum sativum L.

Mahender Kumar, R.K. Agnihotri, R. Vamil and R. Sharma    

Abstract: Coriander commonly known as Dhania or Chinese parsley is generally grown for its use in soups, salads, dressing vegetables, seasoning and chutney. Effect of two phytohormones viz. GA3 and 2,4-D on seed germination, seedling growth and various physiological and biochemical parameters were studied. The hormones were applied individually in different concentrations (10, 50 and 100 μM concentrations). Both the hormones enhanced the germination percentage, seedling growth (root and shoot length), leaf area, chlorophyll and carotenoid content. The application of these hormones also decreased the germination time. Maximum germination, shoot length, leaf area and carotenoid content was observed in 100 μm concentration of GA3. Root length, chl. a and chl. b was maximum in 50 μM of 2,4-D and 100 μm GA3, respectively. The application of two hormones exhibited a marked increase on all the parameters studied as compared to the control.
