Evidence from transformed tomato plants provides strong evidence that fruit ripening in climacteric plants is caused by ethylene. Describe how a coleoptile growth assay is conducted and what would be the effects of ABA or auxin on growth. ABA may have many roles in seed germination of many plants. Certain seeds germinate in open areas but remain dormant under heavy leaf canopies. Describe the morphological differences between sun plants grown in shade and in bright sun.
