Abstract :

Interaction of different media and organic additives showed significant effects on seed germination of G. densiflorum. Among the different organic additives tomato extracts significantly enhanced seed germination and was found to be the most suitable one for enhance the seed germination, It was also the best among treatments for production of viable protocorms. Highest seed germination was recorded in 5% tomato extract fortified with ½ MS medium than compared to mMS, MS, KC medium. In this study, Tomato was selected to be the best organic additive and ½ MS medium as the suitable medium for seed germination of G.densiflorum when compared to other organic additives like potato and coconut water and different media.
