Abstract:
Microgreens are gaining interest for claimed high nutraceutical
properties, but data on their chemical composition are so far
limited. Although often grown hydroponically, their mineral
requirements are still unknown. This study aimed to provide an
insight into yield, mineral uptake, and quality of basil, Swiss chard,
and rocket microgreens grown in a hydroponic system. With
reference to data reported in literature for the same species
hydroponically grown but harvested at adult stage, these
microgreens yielded about half, with lower dry matter percentage,
but higher shoot/root ratio. They showed high concentrations of
some minerals, but their nutrient uptake was limited due to low
yield. Nitrates content was lower if compared with that usually
measured in baby leaf or adult vegetables of the same species, as
well as the concentration of chlorophylls, carotenoids, phenols,
and sugars. Therefore, microgreens seem to be interesting and
innovative low-nitrate-salad crops requiring low fertiliser inputs.
Nevertheless, an improvement in yield as well as in the content of nutraceutical compounds would be desirable.
