| 本文主要研究甘薯块根发育早期。即插植后40天的膨大块根中木质部内单位面积的筛管束数与收获期的淀粉含量有明显的相关性,可以作为甘薯高淀粉育种的早期鉴定的指标。 |

| Abstract: |
| In 1980,some data concering the morphological characters during the process of tuber formation were acquired which lead to conclusio- ns quite different from those of previous studies.Primary and secon- dary cambiums and a lot of their derivatives were also found at abo- ut 40 days after planting.When the volume of tubers was increasing remarkably,especially a considerable number of sieve tubes directly related with starch accumulation was also observed at the same time. It was discovered that the numbers o... |
