Using beneficial microorganisms as biostimulants is a promising strategy to enhance crop growth and productivity in hydroponic systems. has demonstrated plant growth-promoting effects in soil cultivation; however, its efficacy in hydroponic Deep-Water Culture (DWC) systems remains underexplored. This research evaluated the effect of strains TaMFP1 and TaMFP2 on the growth, nutrient uptake, and visual quality of hydroponically grown spinach cv. Stella Plus F-1 ( L.). A randomized complete design was used, comparing inoculated plants with a control and a commercial product. After 28 days, the results showed that significantly increased plant height (23.1%), collar diameter (21.8%), root length (39.6%), leaf area (22.0%), number of leaves (18.05), and fresh biomass accumulation (23.5%) compared to non-inoculated plants. Furthermore, inoculation with TaMFP1 improved spinach yield by 34.5%, while nutrient analysis indicated enhanced phosphorus and calcium uptake. No significant changes were observed in photosynthetic pigment concentrations, and the visual quality of the harvested spinach was unaffected. These findings highlight the potential of as a sustainable biostimulant in hydroponic spinach production. These results contribute to developing beneficial microorganism-based strategies to enhance the sustainability of hydroponic agriculture.
使用有益微生物作为生物刺激剂是提高水培系统中作物生长和生产力的一种有前景的策略。 已在土壤栽培中证明具有促进植物生长的作用；然而，其在水培深水栽培（DWC）系统中的功效仍未得到充分研究。本研究评估了 菌株TaMFP1和TaMFP2对水培菠菜品种Stella Plus F-1（ ）生长、养分吸收和外观品质的影响。采用随机完全设计，将接种植物与对照和一种商业 产品进行比较。28天后，结果表明，与未接种植物相比， 显著增加了株高（23.1%）、茎粗（21.8%）、根长（39.6%）、叶面积（22.0%）、叶片数（18.05）和鲜生物量积累（23.5%）。此外，接种TaMFP1使菠菜产量提高了34.5%，而养分分析表明磷和钙的吸收增强。光合色素浓度未观察到显著变化，收获菠菜的外观品质也未受影响。这些发现突出了 在水培菠菜生产中作为可持续生物刺激剂的潜力。这些结果有助于制定基于有益微生物的策略，以提高水培农业的可持续性。
