摘 要 ：研究了我国广东佛山栽培的菊科(Asteraceae)植物黄莺花(Solidago canadensis var. gilvocanescens Rydb.)的染色体数目和核型。其染色体数目为2n=18，带有一对随体，核型公式为2n=2x=18=14m+4sm (2SAT)，核型类型为“2A”型。

Abstract:The chromosome number and karyotype of a cultivar in the Asteraceae, Solidago canadensis var. gilvocanescens Rydb., cultivated in Foshan City, Guangdong Province, China, were reported. The chromosomes were counted to be 2n=18, and one pair of them had satellites on their short arms. The karyotype was formulated as 2n=2x=18=14m+4sm (2SAT), and belonged to Stebbins’ 2A type.
