INTER-VARIETAL DIFFERENCES IN XYLEM EXUDATE COMPOSITION AND GROWTH UNDER CONTRASTING FORMS OF N SUPPLY IN CUCUMBER

摘要

Variations in the inorganic and organic composition of xylem exudate, growth and N content under contrasting forms of N supply in three cucumber cultivars (Hyclos, Medusa and Victory) were studied in glasshouse conditions. The plants were grown hydroponically with two NO3-:NH4+ ratios (100:0 and 60:40).
