in their digital biomass (whether or not treated with Megafol®).The drought-stressed plants showed, instead, a much lower digi-tal biomass (Fig. 4A) with concomitant fresh weight losses, whencompared to their controls. For the drought stressed plants, thehigher digital biomass detected in the Megafol®treated plants wasmaintained throughout the experiment, even after irrigation of theplants was reinstated for a recovery phase.
