摘 要 ：报道了鳢肠的核型公式K(2n)=22=16m+6sm,核型为“1A”型,其染色体相对长度组成为2n=22=10M₂+12M₁,染色体总长度为29.31μm,对其体积也进行了计算。

Abstract:The authors report that the karyotype formula of Eclipta prostrata is K(2n)=22=16m+6sm, which belongs to "1A" of stebbins, the chromosome eomposition based on relative length is 2n=22=10M₂+12M₁, and the total length of the chromosome is 29.3μm. The chromosome volume of E. prostrata has also been calculated.
