摘　　要：株型是影响作物产量和品质的重要性状之一,而矮化株型对于很多作物都是一种优良的农艺性状。通过采用株型矮化的品种,合理选择种植密度,可充分利用土地空间、提高光能利用率、增加单位面积产量。研究表明,植物激素尤其是赤霉素、油菜素内酯、生长素,在调控植株株高方面发挥了重要作用,目前已有多个相关基因被鉴定或克隆。笔者总结了近年来报道的与植物激素调控瓜菜植物矮化性状相关的基因,为揭示植株矮化机制以及植物种质资源改良提供参考。Plant architecture is one of the most important traits affecting crop yield and quality,and dwarfing plant type is an excellent agronomic trait for many crops.By adopting dwarfing varieties and rationally selecting planting density,land space can be fully utilized,light energy utilization rate can be improved and yield can be increased.Studies have shown that plant hormones,especially gibberellin,brassinolide and auxin,play an important role in the regulation of plant height.So far,many related genes have been identified or cloned.In this review,the author summarizes the genes related to plant hormones regulating Cucurbits and vegetable plants dwarfing traits reported in recent years,providing references for revealing the mechanism of plant dwarfing and improving plant germplasm resources.
