Nanobubbles (NBs) are minuscule gas bubbles with distinct properties
that have shown promise for application in hydroponic horticulture.
This study aimed to evaluate the effect of O2 NBs on plant growth and
tipburn injury of crispy lettuce (Lactuca sativa var. crispa) cultivated in
a commercial nutrient film technique (NFT) system. Seedlings were
transplanted to NFT channels that were irrigated with a O2 NB super-oxygenated
nutrient solution or a non-aerated control. At harvest (4–5 weeks after transplanting),
there were no significant differences between the two treatments in terms of shoot
fresh weight, leaf length, number of leaves, or tipburn severity and incidence. In conclusion,
NBs may not promote growth of certain crops in systems where plant roots are not
continuously submerged or exposed to oxygen- or nutrient-limiting conditions
