| Abstract:
Several scientific researches indicate 32°C as a limit of temperature to inhibit lycopene synthesis and the occurrence of a decay of some qualitative parameters of tomato fruits. In Southern Italy, during 2005, an experimental trial to study the effects of kaolin (Surround® WP) treatments on two high lycopene tomato cultivars (‘HLY 18’ and ‘Tiziano’), had been realized. After kaolin applications, that form a white powdery film on vegetations and fruits, the inner temperature of fruits was measured. The main results show that the fruits temperature treated with kaolin were about 3.5°C lower than the control, at midday of the hottest days. Marketable yield of treated crops was 26.0% higher than untreated, probably for a reduction of rotten fruits. Kaolin treatments increased trans-lycopene fruit content on average of 14.0% in respect to the control, while no influence on other qualitative parameters was observed. Finally, kaolin contributed to reduce the pests damages in both cultivars. | |
