The effect of a flat plastic film covering on the development of lettuce


, : The effect of a flat plastic film covering on the development of lettuce. Acta Horticulturae (42): 255-271

In trials at St. Katelijne-Waver, Belgium, and Geisenheim, Geman Federal Republic, lettuce was covered with polytheylene film for 8, 15, 21 or 23 days after planting out. In the drier, sunnier, more continental climate of Geisenheim the average fresh and dry weights were lower than at St. Kateligne-Waver and leaf size was smaller although leaf number was greater. The effects of the polyethylene covers at the 2 places are discussed. At Geisenheim 8 days under cover was sufficient whereas at St.
