Abstract:

The differentiation period of flower buds in different horticultural plants is slightly different,and the differentiation time is different. The internal factors affecting flower bud differentiation include endogenous hormones and nutrients. Endogenous hormones mainly include auxin,gibberellin,abscisic acid and cytokinin. Light,temperature,moisture and mineral nutrition can affect the flowering of horticultural plants by regulating hormone levels. Flower bud differentiation mechanism includes the C/N ratio theory,hormone balance hypothesis,hormone signal regulation hypothesis and nutrition hypothesis. At the same time,with the further study of flower bud differentiation in horticultural plants,researchers have found that the process of flower bud differentiation is related to the expression of related genes. This paper reviewed the research progress on flower bud differentiation of horticultural plants in recent years, and looked forward to the main research directions in the future.

Key words: horticultural plant, flower bud differentiation, influencing factor
