摘　　要：本文综述了木兰科植物的种苗无性繁殖和种子繁殖相关研究。种苗无性繁殖有利于植物快速、大量繁殖以及保持品种优良特性;扦插、嫁接和组织培养等技术手段常被应用于木兰科植物的工厂化育苗和辅助性研究,其中以嫁接技术应用较为广泛。种子繁殖具有遗传多样性丰富、经济适用和携带方便等诸多优势,针对木兰科植物种子在贮藏和萌发过程中可能出现霉烂现象,可采取浸种消毒和土壤消毒等方式避免种子霉烂;该科种子具有形态休眠和生理休眠特性,可采用赤霉素、强氧化剂浸种处理或低温层积等方式来打破其休眠状态,提高萌发率。研究结果为木兰科植物资源的保护与产业发展提供参考。The research on asexual propagation and seeds propagation of Magnoliaceae plants was reviewed.Asexual propagation of seedlings is beneficial for plants to reproduce rapidly and massively,as well as maintain the excellent characteristics of the variety;techniques such as cutting,grafting,and tissue culture are often applied in the industrial seedlings cultivation and auxiliary research of Magnoliaceae plants.Seeds propagation has many advantages such as rich genetic diversity,economic applicability,and easy portability.In response to the possible occurrence of mold and rot in seeds of Magnoliaceae plants during storage and germination,methods such as soaking and soil disinfection can be adopted to avoid seed mold and rot;the seeds of this family have morphological and physiological dormancy characteristics,which can be broken by soaking them in gibberellins,strong oxidants,or low-temperature stratification to increase their germination rate.The research results provide references for the protection and industrial development of Magnoliaceae plant resources.
