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。
In this study, 20 combinations of sugarcane seedlings were used as materials, and pot and field experiments were conducted to study the relationship between root traits and aboveground traits in sugarcane families. The results showed that there was a significant correlation between root length and root surface area and root volume. Root length, root surface area, root diameter and root volume were significantly and significantly correlated with plant height, stem diameter, brix and survival rate Among them, root length, root surface area and root volume were significantly correlated with plant height; root volume and root yield were significantly correlated.
