| Abstract:
In this study, 0, 15, 30, 60 and 90 ppm doses 4-CPA were applied by one or twice on opened flowers of F-144 (Fantastic) tomato variety grown under greenhouse. At the end of experiment, the yield per plant, fruit shape, and quality were investigated. In addition to these, amounts of 4-CPA residue into ripened fruits were analyzed by using densitometric TLC method. According to the results, the highest yield per plant and good quality fruits was obtained 60-ppm doses of 4-CPA applied twice. 4-CPA analyses determined by densitometric method after TLC have shown that 4-CPA in the ripened fruits were not detectable at ng level | |
