Beschreibung:
<jats:p>The experiment was conducted to determine the effects of CO, enrichment (900 μl·liter<jats:sup>-1</jats:sup>, 8 hours/day) in combination with supplementary lighting of 100 μmol·s<jats:sup>-1</jats:sup>·m<jats:sup>-2</jats:sup>(16-h photoperiod) on tomato <jats:italic>(Lycopersicon esculentum</jats:italic> Mill.) and sweet pepper <jats:italic>(Capsicum annuum</jats:italic> L.) seedling growth in the greenhouse and subsequent yield in the field. Enrichment with CO<jats:sub>2</jats:sub> and supplementary lighting for ≈ 3 weeks before transplanting increased accumulation of dry matter in shoots by ≈ 50% compared with the control, while root dry weight increased 49% for tomato and 6270 for pepper. Early yields increased by =1570 and 11% for tomato and pepper, respectively.</jats:p>
