The effects of calcium to magnesium ratio on the increments of dry weight and protein content in tomatoes

J. Buczek, K. Leonowicz-Babiak

Abstract


A change in the ratio of Ca: Mg ions in the medium or soil from optimum (3:1) to disfavourable values (3:30) causes dwarfing of tomatoes, a decrease of dry weight increment and of protein content. Total-N and protein-N also decrease, whereas the amount of soluble-N increases. It is suggested that the low ratio of Ca:Mg in the medium or soil affects nitrogen metabolism causing a restriction of protein synthesis.
