| Abstract: | The karyotype analysis was carried out on Altemanthera Ficoidea cv. 'Ruliginosa' using root tips of cutting seeds as materials. The results indicated that the chromosomes were counted to be 2n=2x=34. The karyotype formula was 32 m+2 sm. The karyotype type was 2B. The study would provide some references for breeding and utilizing of Altemanthera Ficoidea cv. 'Ruliginosa'. |
