生根剂促进菊花扦插生根的研究进展

菊花拥有较高的观赏价值，在食品、药剂、保健品和化妆品等行业中也有着广泛应用。随着菊花功能的不断开发，其市场需求逐年增加，而其繁殖速度和成苗品质成了影响菊花产业发展的重要因素之一。扦插苗能保持母株的优良性状且繁殖系数较高，是菊花种苗供给的主要繁殖途径。由于扦插存在着生根时间长、生根数量少等问题，因此提高菊花插穗的生根质量、缩短生根时间对菊花的产业发展具有重要意义。本文对目前使用的促进菊花扦插生根的生根剂进行系统综述，并对其未来发展趋势进行展望，为菊花大规模工厂化育苗提供理论依据。

Research progress on rooting of chrysanthemum cuttings promoted by rooting agents

Chrysanthemums have a high ornamental value and are widely used in food, pharmacy, health products and cosmetics. With the continuous development of functions, the market demand for chrysanthemums has increased, and its propagation speed and seedling quality have become one of the important factors affecting the development of chrysanthemum industry. Propagation by cuttings can maintain the excellent traits of the mother plant, and the reproduction coefficient is high, which is the main propagation method for chrysanthemum seedling supply. However, cuttings have problems such as long rooting time and low number of rooting, so improving the rooting quality of chrysanthemum cuttings and shortening the rooting time are of great significance to the industrial development of chrysanthemum. In this paper, the rooting agents currently used to promote the rooting of chrysanthemum cuttings were systematically reviewed, and their future development trends were prospected, so as to provide a theoretical basis for large-scale factory seedlings breeding of chrysanthemum.
