Cellule. 1976;71(2):229-50.

Karyotypes of 18 species of the sections Scutati (2), Vesicarii (2), Hastati (4), Afroacetosae (2) and Acetosa (8) of the genus Acetosa have been investigated in detail. 2. Four evolutive tendancies were distinguished i.e.: decrease of chromosome number and arm ratio, increase of chromosome length and differentiation of sex crhomosomes. These tendancies are fully expressed in the section Acetosa as compared with the others. 3. In this section, relationships between the subsections Acetosa, Insectivalves and Americanae were established especially dealing with the change of sex determination from the type XX/XY to the type XX/XY1Y2. 4. Evolutive pathways within the genus Acetosa as well as in the whole group of Rumex sensu lato are described.

对酸模属盾叶组（2种）、囊果组（2种）、戟叶组（4种）、非洲酸模组（2种）和酸模组（8种）的18个物种的核型进行了详细研究。2. 区分出了四种进化趋势，即：染色体数目和臂比降低、染色体长度增加以及性染色体分化。与其他组相比，这些趋势在酸模组中得到了充分体现。3. 在该组中，建立了酸模亚组、食虫亚组和美洲亚组之间的关系，尤其涉及性别决定从XX/XY型到XX/XY1Y2型的变化。4. 描述了酸模属以及广义酸模属整个类群的进化途径。
