Abstract

Butterhead and cos type lettuce (Lactuca sativa L.), cv. "Bellona" and "Paris cos island" respectively, were grown in nutrient film culture, under various electrical conductivity levels (1.5-2.0-2.5-3.0-4.0-5.0 mS).

Fresh and dry weights of shoots ad roots were measured for their seasonal growth, over a period from October to May, under an unheated glasshouse.

For both cultivars the overall effect of solution conductivity on shoot fresh weight, was minor.

Increases in conductivity resulted in increased root dry weight.
