Abstract

Abstract: The methods of eliminatingwalls by enzymolysis and low osmosis were used to analyse the cell
chromosome karyotype of Lavandula angustifolia Mill. and L. pinnata L. The karyotype formula of L. angus
tifolia Mill. is 2n = 2x = 50 = 14m + 10 sm ( SAT) + st, the species chromosome comp lement based on rela
tive length is 2n = 50 =L + 11M2 + 13M1, which belongs to“2A”type. And the karyotype formula of L. pin2
nata L. is 2n = 2x = 22 = 6m + 5 sm ( SAT) , the species chromosome comp lement based on relative length is
2n = 22 = s + 6M1 + 2M2 + 2L, which belongs to“2B”type.

Key words: Lavandula angustifolia Mill., Lavandula pinnata L., Chromosome, Karyotype
