Abstract

OBJECTIVE:

To study Lonicera japonica Thunb. and Lonicera maackii (Rupr. ) Maxim. chromosome number, karyotype, volume.

METHODS:

Sections combined with micrograph were used to analyse chromosome.

RESULTS:

Lonicera japonica Thunb. normal diploid 2n = 18; the relative length was 2n = 18 = 2L +8M, + 6M1 + 2S; karyotpye formula was K(2n) = 2X = 18 = 10 sm + 6 m + 2st, which belong to "2A" type; the AS. K% was 66.65%. Lonicera maackii (Rupr.) Maxim. normal diploid 2n = 18; the relative length was 2n = 18 = 4L + 4M, + 10M1; karyotype formula was K(2n) = 2X = 18 = 10 sm + 8m, which belong to"2A" type; the AS. K% was 63.28%.

CONCLUSION:

The chromosome number, karyotype, and chromosome volume of Lonicera japonica Thunb. and Lonicera maackii (Rupr.) Maxim. were showed clear.
