Germination, in vitro Propagation and Acclimatization in Lavandula Angustifolia
This research focused on finding the best method for seed in vitro germination in Lavandula angustifolia and optimizing the medium for plant propagation. Seeds were sterilized and subjected to various treatments to break dormancy, then placed on half-strength MS (1/2MS) or distilled H2O + phytagel....
