摘要
研究结果表明,水稻抗旱性与发芽后的种子根粗呈显著正相关;5叶时下位根粗品种问呈极显著差异。据此,可在拔节期通过目测选择根粗的抗旱材料。
The results showed that there was significant correlation between drought resistance and seed root thickness after germination in rice. And it can be an index of resistant variety for early room selecting. There was significant differences among varieties in thickness of lower root at five leaves stage, and its thicker root can be selected through visual estimation at seedling stage for further identification if its real resistant ability in field.
