英文摘要Reported in this paper is a karyomorphological study on one natural population of each of eight varieties in the Spiraea japonica complex. The interphase and mitotic prophase can be classified into the simple chromocenter type and the proximal type, respectively. The metaphase karyotypes of the eight varieties were formulated as follows: S. japonica van japonica: 2n = 18 = 14m + 2sm + 2st; S. japonica var. acuta: 2n = 18 1m + 4sm + 3st; S. japonica var. incisa: 2n = 18 = 12m + 4sm + 2st; S. japonica var. stellaris: 2n = 18 = 15m + Ism + 2st; S. japonica var. acuminata: 2n = 18 = 14m + 2sm + 2st; S. japonica var. ovalifolia: 2n = 18 = 10m + 2sm + 2st + 4t; S. japonica var. glabra: 2n = 18 = 10m + 4sm + 4st; S. japonica var. fortunei: 2n = 36 = 17m + 16sm + 3st. Karyomorphological study reveals that the chromosome numbers within the complex are stable, and that karyomorphological divergence between the varieties lies mainly in chromosome size and organization. Based on the karyomorphological data and geographical distribution of the complex, the differentiation pattern as well as evolutionary mechanism of the complex is evaluated.
