Sexual reproduction in C. moniliferum is described for the first time. The morphology of conjugation is quite like that of C. ehrenbergii. Homothallic strains of both species usually produce single zygospores between daughter cells that have just divided. However, 2 homothallic clones of C. moniliferum form twin zygospores between conjugants which have paired before division and conjugation. This has not been observed in C. ehrenbergii. Heterothallic strains of both species form twin zygospores in the same manner. Heterotfiallisrn seems a well-established feature in both species. Germination and the survival of 2 products of meiosis arc typical of other desmids which have been investigated.
首次描述了念珠藻的有性生殖。接合的形态与埃伦贝格念珠藻非常相似。这两个物种的同宗配合菌株通常在刚分裂的子细胞之间产生单个接合孢子。然而，念珠藻的2个同宗配合克隆在分裂和接合前已配对的接合体之间形成双接合孢子。在埃伦贝格念珠藻中未观察到这种情况。这两个物种的异宗配合菌株以相同方式形成双接合孢子。异宗配合似乎是这两个物种中一个已确立的特征。减数分裂的2个产物的萌发和存活是已研究的其他鼓藻类的典型特征。
