| 摘 要： | 通过对同一品种掖单22(YD22)不同大小子粒玉米种苗转化过程中的生理特性研究发现,小粒YD22的发芽势显著大于大粒YD22,但二者的发芽率差异不显著。小粒YD22胚本体对贮藏物质的运转、消耗率大于大粒YD22,但物质效率低于大粒YD22。大粒YD22 ATP含量高于小粒YD22,尤其在萌发4 d后表现明显。 |

| Abstract: | The physical characteristic of different size maize of a cultivar Yedan 22 during seed-seedling transformation was studied.The germination vigor of the smaller size seed is significant greater than that of the bigger size seed and the both have no significant difference on germination capacity.The smaller size seed has greater substance transferring rate and substance consuming rate than the bigger size seed,while the earlier has lower substance efficiency than the latter.The bigger size seed has higher ATP content than the smaller size seed,which is more remarkable since four days after germination. |
