Abstract
A plant with four and one with six extra A chromosomes were discovered in a hybrid swarm involving Liatris aspera and Liatris spicata. In each plant, the extra chromosomes formed trivalents with chromosomes of the normal complement. This pairing behavior indicates that of the ten chromosomes in the complement the plants are triplicate for four and six chromosomes, respectively.
摘要
在一个涉及糙叶蛇鞭菊和穗状蛇鞭菊的杂交群体中，发现了一株有4条额外A染色体的植株和一株有6条额外A染色体的植株。在每株植物中，额外染色体与正常染色体组中的染色体形成三价体。这种配对行为表明，在该染色体组的10条染色体中，这两株植物分别有4条和6条染色体是三倍体。
