The effect of [K.sub.2]S[O.sub.4] on this variable can be explained by the fact that S participates in chlorophyll synthesis and formation of ferredoxin, which acts as electron carrier in photosynthesis, thus favoring the accumulation of carbohydrates and other nitrogen compounds (LESTER et al., 2005), since ascorbic acid is synthesized from sugars produced in the photosynthesis.
