摘　　要：茭白作为中国第二大水生蔬菜,是由茭白黑粉菌侵染菰使其茎膨大产生肉质茎进而形成的,此过程受到多种因素的影响。通过综述孕茭机制,包括植物激素的差异调控、糖代谢产物以及过氧化物酶活性在茭白孕育过程中的功能与作用。生长素(3-indoleacetic acid,IAA)在茭白膨大过程中发挥着重要作用,有助于茭白孕茭;糖类同化物质在茭白茎的发育过程中扮演着重要角色;过氧化物酶不仅能有效清除体内的活性氧,还对茭白的形成具有重要调节作用,最后对茭白的研究方向及其孕育机理进行了展望。As the second largest aquatic vegetable in China,Zizania latifolia is formed by the infection of Zizania latifolia by Ustilago esculenta,which causes its stem to expand and produce fleshy stems.This process is affected by many factors.This paper primarily examined the mechanism underlying the culm-swelling of Zizania latifolia,including the differential regulation of plant hormones,the function and role of sugar metabolites and peroxidase activity in the process of Zizania latifolia inoculation.3-indoleacetic acid(IAA)played an important role in the expansion process of Zizania latifolia,which was helpful to the culm-swelling of Zizania latifolia.Carbohydrate assimilates also played an important role in the development of Zizania latifolia stems.Peroxidase could not only effectively scavenge reactive oxygen species in vivo,but also play an important regulatory role in the formation of Zizania latifolia.Finally,the research direction and the mechanism of culm-swelling in Zizania latifolia were explored.
