Abstract

Beneficial rhizobacteria are multifunctional microorganisms that stimulate plant growth through direct mechanisms such as the solubilization of phosphorus and potassium present in soil minerals, biological nitrogen fixation and production of plant hormones. The objective of this study was to determine the effect of beneficial rhizobacteria on the initial development, promoting growth and resistance of soybean seedlings, aiming not only for increased production but also for agricultural sustainability through the maximization of biological efficiency in the early development of soybean seedlings. The experiment, under controlled conditions, was conducted in a completely randomized design, with four treatments and ten replications. The treatments consisted in the microbiolization of soybean seeds with: 1. Control (without microorganism); 2. Serratia marcenses (BRM 32114); 3. Bacillus spp. (BRM63573) and 4. BRM 32114 + (BRM63573). After the microbiolization of the seeds, they were sown and placed to germinate, after 12 days, the seedlings were harvested and divided into shoots and roots. The roots were washed and photographed with digital camera. The images were analyzed and determined length, diameter, surface area and volume of roots. Then, root and shoot were dried and weighed for biomass determination. Co-inculation, BRM 32114+ BRM63573, promoted greater robustness of the root system of soybean seedlings with increased length (16.2%), diameter (22.5%), volume (43.4%) and dry biomass (29.7%). The dry matter of shoots and total soybean seedlings was superior to the control treatment in all treatments with rhizobacteria. Therefore, plant growth promoting
大豆幼苗与有益根瘤菌的相互作用
有益根瘤菌是一种多功能微生物,可通过直接机制刺激植物生长,如溶解土壤矿物质中的磷、钾,生物固氮和产生植物激素。本研究旨在确定有益根瘤菌对大豆幼苗初期发育、促进生长和抗性的影响,目的不仅是提高产量,而且是通过最大限度地提高大豆幼苗初期发育的生物效率,实现农业的可持续发展。实验在受控条件下进行,采用完全随机设计,四个处理十次重复。处理包括用以下方法对大豆种子进行微生物处理1.对照组(无微生物);2.大豆沙雷氏菌(BRM 32114);3.芽孢杆菌(BRM63573)和 4.BRM 32114 + (BRM63573)。对种子进行微生物处理后,将其播种并放置发芽,12 天后收获幼苗并将其分为芽和根。根洗净后用数码相机拍照。对图像进行分析,确定根的长度、直径、表面积和体积。然后,对根和芽进行干燥和称重,以测定生物量。BRM 32114+ BRM63573 的共同作用使大豆幼苗根系更加健壮,长度(16.2%)、直径(22.5%)、体积(43.4%)和干生物量(29.7%)均有所增加。在所有使用根瘤菌的处理中,大豆幼苗的嫩枝和总干物质均优于对照处理。因此,促进植物生长的
