用赤霉素和维生素C来控制咖啡早期落果的某些研究工作仍在进行之中,但它们对咖啡的增产效应已确定无疑。本文报道对小粒种咖啡施用维生素C和赤霉素(单用和混用)后的产量效应。据印度中央咖啡研究所记载(表1),在同一小区两年以上的咖啡果产量统计表明,自座果直至收获期间都有落果,其中以六月份落果最多。

Some research efforts to control the early fall of coffee with gibberellic acid and vitamin C are still ongoing, but their effect on increasing the yield of coffee is well established. This article reports on the yield effects of small-grain coffee with vitamin C and gibberellins (single and mixed). According to the Central Coffee Institute of India (Table 1), statistics on the production of coffee cherry fruits in the same district for more than two years show that there is a drop of fruit from the fruit until the harvest, with the most fruit falling in June.
