Abstract
Abstract Plants of lettuce (Lactuca sativa L. cvs. Parris Island Cos and Great Lakes 659) were grown in greenhouses at 2 spacings and with 2 levels of postplanting fertilization with and without CO2 enrichment. CO2 enriched plants averaged 29% higher head fresh weights and 40% higher leaf areas. In terms of fresh weight increases, enrichment response was greater in ‘Great Lakes 659’ than ‘Parris Island Cos’ and in high rather than low fertility treatments. In terms of leaf area increases, low-density treatments responded more than high-density treatments to enrichment. Increases in leaf area with enrichment were similar in the 2 cultivars and the 2 fertilization treatments.
