Abstract
Growth and flowering regulation of horticultural plants such as fruit trees, vegetables and ornamental plants is one of the most important subjects for the management of agricultural production. Gibberellin (GA) is known as a big family in plant hormones which participate in many aspects of plant growth and flowering. In this study, GA biosynthesis and metabolic pathways were identified in many horticultural plants and then, possibility of growth and flowering regulation was investigated by changing GA biosynthesis and metabolism.
