| 摘 要： | 山楂盛花期喷布50—70ppm赤霉素溶液,能增加叶面积和比叶重,但叶片内叶绿素含量略低于对照。赤霉素处理能提高山楂叶片的光合速率,对提高山楂座果率、提高产量有一定作用。

| Abstract: | Spraying 50-70 ppm of gibberellin on maythorn tree at full-bloom stage could increase leaf area and specific leaf weight but it made the chlorophyll content a little lower than ck. Treat with gibberellin could rise photosynthentic efficiency and percentage of fertile fruit and thus increase yield of maythorn. |

| Keywords: | gibberellin maythorn photosynthentic efficiency |
