摘 要 ：报道了鬼针草的核型公式:K(2n)=3X=36=27m+3sm+6sm(SAT),染色体相对长度组成:2n=36=6L+9M₂+18M₁+3S,核型为“2A”型,同时计算了鬼针草的染色体体积。

Abstract:The author reports that the karyotype formula of Bidens bipinnata is K(2n)=3X=36=27m+3sm+6sm (SAT), which be ongs to "2A", and that the chromosome composition based on relative length is 2n=36=6L+9M₂+18M₁+3S. The chromosome volume of B. bipinnata is also calculated.
