本试验对圆果种Savar-D-154和D-154(栽培种),长果种0-4(栽培种)和一个野生种C.trilocularis早未期形成核仁的最大数和晚前期融合核仁附加次缢痕或随体最大数进行了研究。圆果种Savar-D-154,和野生种C.trilocularis在早末期分别有6个和4个核仁,前期末则是6和4条融合核仁附加染色体。D-154和0-4两个品种在早末期形成5个核仁,而在晚前期有6条融合核仁附加染色体。一个核仁的缺失可能是由于形成核仁时一个次缢痕消失的缘故。研究表明:早末期形成核仁最大数与晚前期融合核仁附加染色体或随体数目有关。
In this experiment, the maximum numbers of early kernel nuclei and the early stage fusions of Savar-D-154 and D-154 (cultivated), 0-4 (cultivated) and one wild C.trilocularis The number of nucleoli added with subscripts or the maximum number of subscales was studied. Savar-D-154 and C.trilocularis, the wild species, had 6 and 4 nucleolus, respectively, in the early and late stages, and 6 and 4 additional nucleoli in the early period. Five nuclei of D-154 and 0-4 were formed in the early and late stages, whereas there were six additional nucleoli in the early stage. The absence of a nucleolus may be due to the disappearance of a secondary scar when the nucleolus is formed. Studies have shown that the maximum number of nucleoli formed in early and late stages is related to the number of additional chromosomes or kits accompanying the early nucleophilic nucleolus.
