RESUMO

This study was carried out from April to August, 2005, Piracicaba, Sao Paulo State, Brazil. The objective of this work was to evaluate the effect of the cell recipient and seedlings age on the quality of transplants and tomato (Lycopersicon esculentum Mill) production Netunoin open field. The treatments resulted from the combination of for tray cell sizes 121,2; 34,6; 12,0 e 14,0 cm3 and four transplanting ages (19, 24, 29 e 34 days). It done in a randomized block design ( 4 x 4 factorial). One of the factors was represented by different cell volume and the second factor was transplants age. In the transplant production was evaluated, number of leaves, leaf area, fresh and dry leaves and root mass, seedlings quality (before production was evaluated the same vegetative characteristics) and after transplanting, the earliness, and total yield fruits (number and mass of fruits commercial fruits). The fruits were classified in small, medium and large sizes. The larger volumes (121, 2 e 34, 6 cm³) presented better quality of seedlings than of smaller one (12, 0 e 14, 0 cm³). There was etiolated, stunted, desuniformity, and the cell volume of 12,0 cm³ seedlings was yellows and small. The larger volumes presented higher fresh and dry mass. The better age for transplanting was 24 to 29 days for the larges volumes, being recommended the volume of cell of 34,6 cm³. No significant differences were observed between all treatments for fruits production, however, earliness in larger volumes was observed. Transplants with 24 days age were most productive for earliness. Commercial and total fruits number per plant increment at 19, 24 and also 29 days age. Transplants with 19, 24 days age and larger cell volumes had increased the number and mass of early fruits. The earliness age and the larger cell volume presented higher number and mass of medium fruits. There were not differences for larger fruits for all treatments.
