Abstract: A vacuum infiltration technique that allowed precise control of both infiltration rate and amount of solution administered to whole tomato ( Lycopersicon esculentum ) fruit was developed. Controlled volumes of 5 m m solutions of CuSO 4 , Cu(NO 3 ) 2 , HgCl 2 , CaSO 4 , KNO 3 , (NH 4 ) 2 C 2 O 4 , Na 2 HPO 4 , citrate and 1 m m EDTA or EGTA were infiltrated into intact, mature-green tomato fruit and evaluated with regard to their effect on the pattern of tomato ripening. Copper significantly accelerated lycopene accumulation and influenced both the timing and magnitude of climacteric ethylene production. Infiltration with HgCl 2 elicited similar effects as copper, but severe phytotoxicity was observed. In contrast, CaSO 4 , KNO 3 , and chelators had no significant effect on the pattern of ripening. Copper initiated wound ethylene production in the ripening mutant rin that reached up to 50% of the wound levels observed in normal fruit, but rin was not induced to ripen.
