The studies of Hermans et al.
(2005)showed that in sugar beet, under Mg deficiency, the shoot
growth was more depressed than the root growth and carbohydrates started to accumulate in the leaves of the rosette, which
were the lowest in the Mg concentration. The accumulation of carbohydrates in the above ground tissues restricts photosynthetic
CO2fixation and enhances the formation of reactive oxygen species
