| Abstract: | This paper deals with cytological study on Iris tenuifolia.The number of somatic chromosome in rootstips has been found to be 2n=18, the kanyotype formula of I.tenuifolca is k(2n)=14=6m 8sm(2SAT) and belong to 2A of stebbins karyotype symmetry.The species chromosome compsition of relative length is 2n=14=4M2 10M1.The total length of the chromosome is 32.323m. |
