“…However, few studies have investigated the effects of biostimulant seed treatments on microgreens. Pannacci et al, 18 Gaidau et al 19 and Karbarz et al 20 observed how the application of a plant-, animaland microalga-based biostimulant, respectively, stimulated species-specific germination and hypocotyl elongation. Amirkhani et al, 21 on the other hand, reported how coating seeds with a soybean-based biostimulant improved the growth of broccoli (Brassica oleracea L.) sprouts through an enhancement of nitrogen metabolism.…”

BackgroundMicrogreens constitute dietary sources of bioactive compounds imparting numerous health benefits and enhancing sensory experience. They can be successfully cultivated in soilless systems where biostimulants can be easily integrated as seed priming and post‐germination agents improving the sustainability of the crop's final production. Compared to an untreated control, three priming agents [a commercial legume‐derived protein hydrolysate (A250), a novel protein hydrolysate derived from peanut biomass (H250), and hydropriming (H2O)] were applied to Komatsuna and Mibuna seeds grown as microgreens and compared for their effects, on yield parameters, mineral composition, ABTS and FRAP antioxidant capacity, carotenoid concentration, and phenolic compounds.ResultsSignificant effects of the main experimental factors and their interactions were identified on antioxidant capacity. Compared to the control and hydropriming, the highest ABTS and FRAP values were observed in Mibuna with the A250 and H250 treatments, respectively. Additionally, the H250 treatment increased the total concentrations of phenolic acid derivatives and flavonoid derivatives in Mibuna and Komatsuna, in tune with the levels of total flavonoids. Concerning mineral composition, highest concentrations in both species were those of phosphorus and nitrate.ConclusionThese results highlight the potential of select plant‐based biostimulants as priming agents to enhance the antioxidant capacity, nutrient and bioactive compound contents, thus further increasing their functional and nutritive quality. In the light of this, the possibility of reducing the application of fertilisers by promoting a green transition for the intensive production of microgreens could subsequently be evaluated.This article is protected by copyright.

“…Karbarz et al tested microalgae Planktochlorella nurekis clones obtained by co-treatment with colchicine and cytochalasin on four plant species (lettuce, wheat, broccoli, and radish) to check their potential use as biostimulators in agriculture. Eleven clone extracts showed both a stimulating and inhibitory effect on tested plants (depending on the concentration, plant species, and algal clone); thus, they could potentially be used as biostimulators or natural herbicides [11]. Li et al assembled a mitochondrial genome map of O. javanica (watercress, a very popular vegetable in Asia) using the Illumina and Nanopore sequencing platforms.…”

Microgreens are young plants grown from vegetables, grain, or herb seeds in a controlled environment with artificial lighting. LED modules are the preferred option for indoor and vertical farming. Light intensity (LI) is crucial for plant growth and the synthesis of phytochemicals. The study aimed to assess whether growing microgreens under low light intensity but with the addition of algae would produce plants with similar parameters (biometric, active compound content) to those grown under higher light intensity. The experiment evaluated LED white light at two intensity levels: 115 µmol m−2 s−1 (low light, LL) and 230 µmol m−2 s−1 (high light, HL). Pea seeds were soaked in a 10% solution of Chlorella vulgaris algae or water before sowing, and the plants were watered or sprayed during growth with the same solutions. The results showed no positive effect of algae on plant biometric traits. However, plants treated with algae had a significantly higher chlorophyll and carotenoid content index. Light significantly influenced pea growth, with plants grown under high light (HL) showing greater weight, height, and plant area. Additionally, changes in the photosynthetic apparatus and light stress were observed in microgreens watered with water (AW and WW) under high light during the vegetative phase. Raman spectra also indicated changes in the chemical composition of microgreens’ leaves based on light intensity and treatment. Microgreens treated with algae solution during seed soaking and water during the vegetative phase produced much more carotenoids compared to other variants.
