Ozone effects on the physiology and marketable biomass of leafy vegetables under Mediterranean conditions: Spinach (Spinacia oleracea L.) and Swiss chard (Beta vulgaris L. var. cycla)

摘要

Two open-top chamber experiments were carried out at a continental and a coastal location in Spain to test the ozone sensitivity of spinach (Spinacia oleracea L.) and Swiss chard (Beta vulgaris L. var. cycla) under Mediterranean conditions. Three cultivars of spinach and two cultivars of Swiss chard currently grown in commercial fields were screened for ozone tolerance in terms of marketable yield. Different physiological parameters were measured to identify traits related with this tolerance and ozone effects on yield quality.
