摘　　要：玉米果穗养分运输组织是连接茎秆维管束并将养分运输至籽粒的"流"系统。随着人类日益增高的粮食需求,果穗作为玉米高产、高品质的物质载体,在玉米育种工作中果穗养分运输组织形态结构和生理功能等性状的研究日趋受到重视。通过整理国内外玉米果穗养分运输组织的相关研究进展,总结了玉米果穗养分运输组织的表型性状及其与产量之间的关系,并展望了在基因组学、表型组学发展的背景下,玉米果穗养分运输组织的研究趋势。Maize ear and kernel transport tissue are essential channels which communicate with stem and transport nutrients into kernel. As the rising demand for food,maize ear as the carrier of high yield and high quality whose morphological structure and physiological function of nutrient transport tissue are taken much attention in breeding research recently. Based on the research in China and foreign counties,this paper enumerated the main study methods of maize ear and kernel nutrients transport tissue,summarized its development of phenotypic characters and function and the relationships between yield. Meanwhile,the research direction of maize ear and kernel nutrients transport tissue were prospected in the background of the development of plant genomics and phenomics.
