在花生品种粤油551—116幼苗期(四叶期)停止供水的条件下,用300ppm三唑酮喷施其地上部。以喷清水为对照。处理后测定第二片叶的生理变化。经三唑酮处理的叶片含水量相对提高,脯氨酸含量低于对照,叶片气孔开张度小,使蒸腾作用降低,失水量减少,从而提高了幼苗的抗旱性能。花生幼苗 The peanut variety Yueyou 551-116 seedling stage (four-leaf stage) to stop the water supply conditions, with 300ppm triadimefon spray its aerial parts. To spray water as a control. After treatment, the second leaf physiological changes were measured. The water content of triadimefon treated leaves increased relatively, the content of proline was lower than that of the control, and the stomatal opening of leaves was small, which reduced the transpiration and decreased the water loss, thus increased the drought resistance of seedlings.
