Three greenhouses’ horticultural covers, Celloclim/Polyane 4D and double cover were tried using a culture of tomato, Solanum lycopersicum, cv Durinta harvested 12 and 28 weeks after transplanting. While Polyane 4D permitted the most enlightened conditions, the double cover ensured the greatest means of diurnal and nocturnal temperature. Fruits maturity was firstly recorded under the greenhouse covered by Celloclim. Produced fruits were the heaviest, largest, richest on dry matter content and both potassium, calcium and magnesium; and the sweetest (high savor's index) under the greenhouse covered by Polyane 4D. However, they presented the most elevated content on nitrogen and antioxidant compounds (lycopene, β-carotene, polyphenols, anthocyanine, vitamin C) when harvested from the greenhouse covered by the double cover. Fruits gathered under this last cover were the most impaired by the drastic increment of temperature recorded at the second sampling's date by showing the least fruits’ size yet the highest antioxidant activity and proline concentration considered as a defense mechanism.
