Abstract : Preharvest sprays of GA3 (50 or 75 p.p.m.) or Ethrel [ethephon] (500 p.p.m.) brought forward fruit maturity by 8-11 days and ripening by 10-14 days compared with controls, significantly improved fruit quality (TSS content, sugar, ascorbic acid and ?-carotene concentrations) and reduced spoilage losses during storage, without causing a marked increase in preharvest fruit drop. There was virtually no fruit fly damage with plant growth regulator treatment.
