摘要: 赤霉素100-300 ppm 11月下旬处理水涨龙眼,对花芽分化有一定的影响,但大小年间的反应存在差异,小年各处理间的花穗抽生率呈现出随浓度降低而提高的趋势,低浓度(100 ppm)有明显的促花效应,而大年处理的花穗抽生率无明显差异。所有处理对花穗及夏、秋梢结果母枝的生长发育均无不良影响。

Abstract: Gibberellin at 100-300 ppm was applied to "Shuizhang" long-an trees in late November. Results showed that gibberellin had effects on flower-bud differentiation. The responses of the trees to gibberellin, however,were different in on-year and off-year.Flower cluster rate tended to increase with the decreasing gibberellin concentration. Gibberel-lin at 100ppm had significantly promotive effect on flowering in off-year, whereas it had no effect in on-year. The development of flower clusters, summer and autumn shoots were not adversely affected in all treatments.

Key words: Gibberellin, "Shuizhang", longan, Flower-bud differentia-tion
