| Abstract: | The root-tips ofApium graveolens L.is selected as the materials in this study. The conventional crushing method was used to prepare the slice specimens of chromosomes and its karyotype is analyzed.The results show that the chromosome numbers of Apium graveolens L.is 2n =22, karyotype formula is K （2n） = 2x = 2m＋18st＋ 2t ,and its asymmetrical karyotype coefficient is 81.87%, The chromosome karyotype of Apium graveolens L. is Type 3A. |
