摘要: 通过对67个玉米品种幼苗叶片的水势、抗坏血酸、脯氨酸、电解质渗漏率和萎蔫分数在大田干旱条件下及室内水分胁迫条件下的测定证明,各指标对干旱反应的灵敏度顺序为:抗坏血酸>电解质渗漏率>脯氨酸>萎蔫分数。室内结果可代替大田结果。室内幼苗上述各指标测定结果可用于玉米品种抗旱性鉴定,但是可否用于分级有待进一步研究。

Abstract: Water potential, ascorbic acid, proline, electrolyte leakage and wilting points in seedling leaves of 67 maize varieties were determined under drought conditions in the field and under water stress conditions in the laboratory,Results showed that these indexes were good for determining seedling drought resistance,The sensitivity sequence of these indexes to drought was ascorbic acid, electrolyte leakage, proline, and wilting points. The indexes determined in the laboratory can substitute those determined in the field.The Dormer could be used for variety drouhht resistance appraisal.

Key words: Maize, Drought resistance, Physiology and biochemistry indexes, Variety appraisal
