Root development and shoot biomass of maize plants grown in hydroponics and exposed to a root zone temperature of 12 °C during four weeks in a cooling system. Effects of seed priming with water and Zn/Mn [14] as compared to an untreated control grown under ambient temperature at 20 °C. Data represent means of four independent replicates for each treatment. Significant differences (Tukey test, α < 5 %) are marked with different letters
