| 摘 要： | 从生理特性、形态特征、地上部与地下部关系等方面对杂交水稻与常规水稻秧苗根系进行了比较研究。结果表明：秧苗发根力、根系活力、根系分布、各级根长、根粗、根数以及根毛均以杂交水稻优于常规水稻。秧苗叶鞘、叶片维管束数也以杂交水稻占优势。

| Abstract: | In terms of physiological and morphological characteristics and the relation between aboveground and underground portions.the comparison of root systems of seedlings between hybrid rice and con-ventional rice was conducted.The results showed that hybrid rice was better than conventional rice in rootingcapacity,root vitality,distribution,number,length,thickness and number of root hairs;and it was alsofound that hybrid rice was superior to conventional rice in the number of vascular bundles of leaf sheath andblade in seedling stage. |
