[Karyotype analysis of Lonicera japonica and L. maackii]
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.

LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...
