| 摘 要： | 以甘蔗20个组合实生苗为材料,用盆栽和大田试验研究甘蔗家系根系性状与地上部性状的关系。结果表明:根长与根表面积、根体积变化呈极显著相关;根长、根表面积、根直径、根体积与实生苗新植的株高、径茎、锤度、成活率呈极显著或显著相关;其中,根长、根表面积、根体积与宿根株高呈显著相关;根体积与宿根理论产量呈显著相关。

| Abstract: | The seedlings of 20 combinations were conducted in field and pot experiments to testify the relationship between root traits and plant growth. The results indicated that root length had a significant positive correlation with root surface area and root volume. Root length, root surface area, root diameter, root volume had a significant positive correlation with plant height, diameter, brix, viability of plant crop. Root length, root surface area, root volume had a positive correlation with plant height and root volume was positively correlated with theoretical yield of seedlings ratoon. |
