为了探讨小麦苗期抗旱性鉴定指标,选取了不同基因型的小麦品种26个,运用反复干旱法对其在苗期进行抗旱性鉴定,结果表明:苗期反复干旱法鉴定结果客观、科学,测定方法简便。幼苗存活率与品种的抗旱性趋势一致,抗旱性强的品种存活率高,其可作为苗期抗旱性鉴定指标。
Twenty-six wheat cultivars with different genotypes were selected to evaluate their drought resistance at seedling stage. The results showed that the results of the drought-resistance test in seedling stage were objective, scientific and determined The method is simple. The seedling survival rate is consistent with the drought resistance of varieties, and the survival rate of the varieties with high drought resistance is high, which can be used as the identification index of drought resistance at the seedling stage.
