摘　　要：在本试验所研究的芜菁三个品种中,其生长状况基本相似,出苗后前期,地上部生长迅速,地下部生长较缓慢,且根冠比小于0.2,但是后期,地下部迅速生长,地上部生长较为缓慢,根冠比增加。在源/库活性方面,3个芜菁品种均在前期处于缓慢增长的趋势,后期呈现不同程度的变化。In this study the growth status of three turnips varieties were generally similar. The above ground parts grew rapidly compared with the underground parts in the early period after seedling with the root - shoot ratio less than 0.2. And in the later period after seeding, the underground parts grew rapidly, whereas the above ground parts grew slowly, with an increased root - shoot ratio. The souwe/sink activities of the three turnips varieties kept the trend of slow growth in the early period after seedling and changed differently in the later stage.
