Some effect of CO2, air temperature and supplementary artificial light on the growth of young tomato plants


, : Some effect of CO2, air temperature and supplementary artificial light on the growth of young tomato plants. Acta Horticulturae (39): 175-182

The results are given of 3-year trials with tomatoes sown in late November or early December, in factorial combinations of the following conditions: in normal atmospheric CO2 or enriched with CO2 at 1000 v.p.m.; with or without supplementary light from 06.00 to 18.00 h; and 2 air temperature regimes (20/16 deg and 22.2/18.2 deg C). Supplementary light was the most effective single factor for improving plant growth rate, the time to first flower and the early crop.
