| 摘 要： | 梅树经氟化氢熏气后,离区纤维素酶活力升高,这可能是某些植物受大气氟污染后产生非正常落叶的原因。熏气前喷洒生长调节物质,可以相对降低纤维素酶活力,有效地抑制大气氟污染产生的落叶效应。

| Abstract: | The ceiluiase activity at abscision zone in- creases after fumigation To P run us mume with hydrofluoric acid. This might be the reason for leaf abnormally falling induced by airborne tluoride. By means of spraying growth substances before fumigation, the cellulase activity can be reduced and the effect of airborne fluoride on leaves absci-sion may be partially inhibited. |

| Keywords: | hydrogen fluoride leaf falling cellulase growth substance |
