用卅烷醇的7种胶体浓度和6种乳剂浓度,在玉米苗期进行喷洒盆钵试验。表明卅烷醇对玉米的苗高、地上、地下部分的干重增加有生理活性存在的可能。在设置的三种浓度,喷洒玉米成株(抽雄始期)的田间试验结果表明:喷洒卅烷醇后,玉米生育进程和产量构成因素都无变化。处理之间以及与对照相比,籽粒产量无差异。 Spraying bowl experiments with maize seedlings at seven colloid concentrations of stilbene alcohol and six emulsion concentrations. The results showed that there was a possibility that momilanol may have physiological activity on the seedling height of corn and the increase of dry weight of above and below ground. In the three concentrations tested, the field test results of spraying maize plants (tasselling initiation stage) showed that there was no change in maize growth process and yield components after spraying 卅 alkanol. There was no difference in grain yield between treatments and compared to the control.
