采用盆栽控水法对真甜美6号、穗甜1号进行水分胁迫试验。结果表明:水分胁迫对甜玉米株高影响比较大,对穗位高基本无影响;不同程度水分胁迫下,叶片叶绿素a、叶绿素b和总叶绿素含量均下降,重度胁迫时叶片内叶绿素含量极显著低于轻度胁迫和对照,但a/b值增加。随着胁迫程度增强,产量呈下降趋势,轻度胁迫对产量影响不大。 The potted water control method was used to test the water stress of Zhen Tian Mei 6 and Sui Tian 1. The results showed that water stress had a great effect on the plant height of sweet corn and had little effect on the ear height. Under different degrees of water stress, the content of chlorophyll a, chlorophyll b and total chlorophyll decreased, while the chlorophyll content in the leaves under severe stress was significant Lower than mild stress and control, but a / b values ​​increased. With the degree of stress increased, the yield showed a downward trend, mild stress had little effect on the yield.
