Ectomicorrizas de Pinus spp., coletadas em Vicosa e Itabira, MG, foram caracterizadas macroscopicamente, quanto a cor, forma, tipo de micelio circundante e rizomorfo, e microscopicamente, quanto a presenca ou ausencia de grampos de conexao, rede de Hartig e espessuras do manto, hifas do micelio circundante e rizomorfos. Essas caracteristicas possibilitaram distinguir cinco tipos, tres de Pinus caribaea var. hondurensis (tipos 3, 4 e 5), um de Pinus elliottii var. elliottii (tipo I) e um de Pinus glabra (tipo 2). Para identificar o fungo simbionte das ectomicorrizas caracterizadas, foram aplicados dois ou mais dos seguintes metodos: verificacao de conexao, durante a coleta, entre micorriza e basidicarpo por hifas e/ou rizomorfos; comparacao dos micelios circundantes da micorriza e do basidiocarpo; isolamento do fungo simbionte a partir de ectomicorriza e basidiocarpo e sintese de micorrizas, "in vitro", com culturas isoladas. |

Microorganisms can promote plant growth by increasing phytomass production, nutrient uptake, photosynthesis rates, and grain yield, which can result in higher profits for farmers. However, there is limited information available about the physiological characteristics of lowland rice after treatment with beneficial microorganisms in the tropical region. This study aimed to determine the effects of different beneficial microorganisms and various application forms on phytomass production, gas exchange, and nutrient contents in the lowland rice cultivar 'BRS Catiana' in a tropical region. The experiment was performed under greenhouse conditions utilizing a completely randomized design and a 7 × 3 + 1 factorial scheme with four replications. The treatments consisted of seven microorganisms, including the rhizobacterial isolates BRM 32113, BRM 32111, BRM 32114, BRM 32112, BRM 32109, and BRM 32110 and Trichoderma asperellum pooled isolates UFRA-06, UFRA-09, UFRA-12, and UFRA-52, which were applied using three different methods (microbiolized seed, microbiolized seed + soil drenched with a microorganism suspension at 7 and 15 days after sowing (DAS), and microbiolized seed + plant spraying with a microorganism suspension at 7 and 15 DAS) with a control (water). The use of microorganisms can provide numerous benefits for rice in terms of crop growth and development. The microorganism types and methods of application positively and differentially affected the physiological characteristics evaluated in the experimental lowland rice plants. Notably, the plants treated with the bioagent BRM 32109 on the seeds and on seeds + soil produced plants with the highest dry matter biomass, gas exchange rate, and N, P, Fe, and Mg uptake. Therefore, our findings indicate strong potential for the use of microorganisms in lowland rice cultivation systems in tropical regions. Currently, an additional field experiment is in its second year to validate the beneficial result reported here and the novel input sustainability.
