选用两优培九、汕优63与湘洲8号3个不同类型的水稻品种,通过测定其根重、根长、根体积等根系形态特征以及与地上部的关系,得出在整个生育期,两优培九和汕优63单株根干重、根体积、白根数、总根数和最长根都高于湘洲8号。尤其在水稻生育的完熟期,两优培九和汕优63的根系形态指标都显著或极显著高于湘洲8号。
Three different types of rice cultivars, Liangyoupeijiu, Shanyou 63 and Xiangzhou 8 were selected and their root morphological characteristics, root length and root volume were determined, and the relationship with the aboveground parts was analyzed. The results showed that during the whole growth period, The root dry weight, root volume, white root number, total root number and longest root of Shanyou 63 were all higher than those of Xiangzhou No. 8. Especially in the mature stage of rice growth, the root morphology of Liangyoupeijiu and Shanyou 63 were significantly or extremely significantly higher than that of Xiangzhou 8.
