spp. are widely reported to regulate plant growth by improving nutrient uptake, photosynthesis, and abiotic stress tolerance. However, their possible application for bedding plants is little explored, especially when comparing different growing media. Considering that coconut coir dust is finding broader application in the ornamental plants sector as a peat substitute, this work was aimed to test the combination of AT10 and coconut coir dust on plants. Four treatments were tested as a mix of: (i) two growing media (70:30), peat:perlite or coconut coir dust:perlite; and (ii) the absence or presence of a treatment. At the end of the production cycle, the biomass and ornamental parameters, leaf pigments, nutrient content of the plant tissues, and abundance were assessed. The results revealed that can readily colonize coir, and the same positive effects of inoculum were found in plants grown on both substrates. The biostimulant effect of was observed as an increase in the aboveground biomass, number and weight of flowers, pigments and nutrient concentration, thereby improving the commercial quality of . Thus, has shown its potential in making bedding plant cultivation more sustainable and improving the yield and aesthetic parameters of plants grown on peat and coconut coir dust substrates.
据广泛报道,[具体微生物种类]通过改善养分吸收、光合作用和非生物胁迫耐受性来调节植物生长。然而,它们在盆栽植物中的潜在应用很少被探索,尤其是在比较不同生长介质时。考虑到椰壳纤维粉尘作为泥炭替代品在观赏植物领域得到了更广泛的应用,这项工作旨在测试AT10与椰壳纤维粉尘对植物的组合效果。测试了四种处理组合:(i)两种生长介质(70:30),泥炭:珍珠岩或椰壳纤维粉尘:珍珠岩;(ii)有无[具体处理方式]。在生产周期结束时,评估了生物量和观赏参数、叶片色素、植物组织的养分含量以及[具体微生物种类]的丰度。结果表明,[具体微生物种类]能够很容易地在椰壳纤维上定殖,并且在两种基质上生长的植物中都发现了接种物的相同积极效果。观察到[具体微生物种类]的生物刺激作用表现为地上生物量增加、花朵数量和重量增加、色素和养分浓度增加,从而提高了[具体植物名称]的商业品质。因此,[具体微生物种类]已显示出其在使盆栽植物种植更具可持续性以及提高在泥炭和椰壳纤维粉尘基质上生长的植物的产量和美学参数方面的潜力。
