Attempts at inducing uniform ripening in Robusta coffee (Coffea canephora Pierre ex-Froehner) with 2,4,5-T and GA

, : Attempts at inducing uniform ripening in Robusta coffee (Coffea canephora Pierre ex-Froehner) with 2,4,5-T and GA. Acta Horticulturae (53): 297-303

2,4,5-T at 50 p.p.m. sprayed on green coffee berries produced a significant increase in the percentage of ripe berries over the control; GA at 10 to 500 p.p.m. delayed ripening, but at 1000 p.p.m. produced a non-significant increase.
