I recently sowed Eruca (Rocket plant) seeds in Murashige and Skoog medium. Unfortunately, most seedlings are etiolated after emergence and their growth is very slow. What could be the reason for this?
Note: The light and temperature conditions are quite suitable, and the seed germination potential is high. When we plant the seeds on a layer of paper towels, all the seedlings are completely green.
Even if your light conditions are suitable, light may not be able to penetrate the MS medium effectively. This can happen if the medium is too dense or if the seedlings are covered with a layer that blocks light. Make sure the seedlings are not buried too deep and that the medium does not obstruct the light. It would be a good idea to test how the seeds would grow if they were just placed on the surface of the MS...
