Based on the comparative analysis of style , stigma size , pod length and width , pod surface area , seed diameter and dry weight between amphidiploids and their putative diploid ancestors , we observed that some accessions of amphidiploids revealed intermediate state between the two putative parents , others resembled only one of the parents 摘要通過比較分析薹屬多倍體復(fù)合種與其祖先二倍體基本種在花柱、柱頭大小、角果長度、寬度、種子直徑及種子干重變化上的異同,發(fā)現(xiàn)多倍體復(fù)合種在這些發(fā)育性狀上表現(xiàn)出處于兩個(gè)祖先二倍體親本之間,或只偏向于其中一個(gè)祖先親本。
