Abstract Highlights

The experiment took from august to December 1995 in Chapingo, Mexico in a greenhouse where the average minimum and maximum temperatures were 12.7 and 27.8 °C respectively. The variety used was CHF1, selection 10 Different concentration of gaseous CO2 These concentration were combined with different moments in the development of the plant (seedling emergence, first flower, 10 bags per plant, first full fruit, second harvest and all the previous ones) The 24 treatments were evaluated under a complete random plot design with a factorial arrangement with 4 replictions per treatment. Fruit production increased in 52 and 48% with the addition of 300 and 1200 ppm compared to the control The number of fruit per plant, dry weigh of roots, stems, fruits and total were higher with the application of carbonated water, in particular the total dry with 1200 ppm of CO2 increased 45% compared with the control There was aiso more elongation of plants (intermode length and height to the first sympodium) and leaf are with the application of CO2 to the roots. Fruit production and dry weight in the different parts of the plant were significatively affected by the time of application of carbonated water. It was observed that the application at the time of 10 bags of fruit induced higher dry weght and in roots, stems and leaves, but the plants were obtained with 300 and 1200 ppm of CO2- during the stage of 10 bags of fruit per plant.
