Abstract
Bio-stimulants are showing growing success and are gradually replacing synthetic fertilizers in agriculture. Wood distillate (WD), also known as wood vinegar or pyroligneous acid, is a by-product of biomass pyrolysis and is increasingly used as a bio-stimulant for crop production. The purpose of this work was to test two types of WD utilizations: (i) pure WD (from BioDea®) and (ii) WD combined with 3% soy lecithin and 5% flavonoid-rich wood glycolic extract (BF; BioDea Flavor®), at concentrations of 0.25% and 0.50%. Our results indicate that foliar applications of both WD and BF increased chlorophyll content, biomass, and starch content in the treated lettuce, while WD, at a concentration of 0.50%, also increased glucose and fructose content. All the treatments were found to be safe, as neither of them showed a significant increase in the content of potentially toxic elements (PTEs) in lettuce.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
