“…They were then subcultured in liquid LB medium and incubated at 28 °C, 180 rpm, for 72 h, until the exponential phase of bacterial growth (1.0 × 10 9 CFU mL −1 ) [ 69 ]. The inoculant containing the strain pant001 ( Bacillus subtilis —Panta Premium) [ 70 ] was provided by the Geoclean company, and, together with the bacteria subcultured in liquid medium, they were used directly in the inoculation of the seeds.…”

A strategy using bacilli was adopted aiming to investigate the mitigation of the effects of water deficit in sesame. An experiment was carried out in a greenhouse with 2 sesame cultivars (BRS Seda and BRS Anahí) and 4 inoculants (pant001, ESA 13, ESA 402, and ESA 441). On the 30th day of the cycle, irrigation was suspended for eight days, and the plants were subjected to physiological analysis using an infrared gas analyzer (IRGA). On the 8th day of water suspension, leaves were collected for analysis: superoxide dismutase, catalase, ascorbate peroxidase, proline, nitrogen, chlorophyll, and carotenoids. At the end of the crop cycle, data on biomass and vegetative growth characteristics were collected. Data were submitted for variance analysis and comparison of means by the Tukey and Shapiro–Wilk tests. A positive effect of inoculants was observed for all characteristics evaluated, contributing to improvements in plant physiology, induction of biochemical responses, vegetative development, and productivity. ESA 13 established better interaction with the BRS Anahí cultivar and ESA 402 with BRS Seda, with an increase of 49% and 34%, respectively, for the mass of one thousand seeds. Thus, biological indicators are identified regarding the potential of inoculants for application in sesame cultivation.

IntroductionWater scarcity is a challenge for sesame cultivation under rainfed conditions. In this scenario, a potential strategy to alleviate the water deficit is the application of plant growth-promoting bacteria. The objective of this study was to analyze the interaction of rhizobacteria with sesame cultivation under water deficit conditions.MethodsAn experiment was conducted in pots in a greenhouse using the BRS Morena sesame cultivar. The experimental design was completely randomized in a factorial scheme: 2 (irrigation regimes - daily irrigation and water deficit by suspending irrigation until 90% stomatal closure) x 6 (treatments with nitrogen or inoculants), with 5 replications. The types of fertilization were characterized by the addition of nitrogen (ammonium sulfate; 21% N), inoculants based on Bacillus spp. (pant001, ESA 13, and ESA 402), Agrobacterium sp. (ESA 441), and without nitrogen (control). On the fifth day after the suspension of irrigation, plant material was collected for gene expression analysis (DREB1 and HDZ7), activities of antioxidant enzymes (superoxide dismutase and catalase), relative proline content, and photosynthetic pigments. At the end of the crop cycle (about 85 days), production characteristics (root dry matter, aboveground dry matter, number of capsules, and thousand seed weight), as well as leaf nitrogen (N) and phosphorus (P) content, were evaluated.Results and DiscussionThere was a positive effect on both production and biochemical characteristics (proline, superoxide dismutase, catalase, and photosynthetic pigments). Regarding gene expression, most of the inoculated treatments exhibited increased expression of the DREB1 and HDZ7 genes. These biological indicators demonstrate the potential of rhizobacteria for application in sesame cultivation, providing nutritional supply and reducing the effects of water deficit.

“…Dentre estas novas tecnologias de manejo está a inoculação de sementes a partir de microrganismos biológicos, que teve um aumento considerável de uso em culturas agrícolas nos últimos anos (de Carvalho, et al, 2023). Grande parte desse aumento se deve ao potencial de complementar e/ou substituir produtos químicos para manutenção da sanidade vegetal e controle biológico de pragas e doenças de plantas, entre outros usos, que potencialmente favorecem a redução de custos produtivos e a preservação do meio ambiente (Nonato, 2016;Diaz, et al, 2019;Chagas Júnior et al, 2021).…”

Este trabalho objetivou avaliar mediante experimentação a campo, a resposta da inoculação associado com três lotes de sementes distintos, utilizando sementes comerciais de soja, sementes salvas e sementes expostas ao sol (simulando condições de armazenagem e/ou transporte inadequado). Os tratamentos foram divididos em quatro épocas de coleta, de acordo com os estágios reprodutivos R1, R2, R4 e R6. Durante a condução do experimento foi realizado a contagem de nódulos totais (n-total), ativos (n-ati) e inativos (n-ina), massa de nódulos presentes na raiz principal (n-prin), massa de nódulos das raízes secundárias (n-sec), massa seca de raízes (ms-r), massa seca de folhas (ms-f), massa seca de vagens (ms-v), massa seca do caule (ms-c), número de vagens (n-vag) e sementes por planta (n-sem), rendimento por planta (Rend) e peso de mil sementes (PMS). Todas as avaliações foram realizadas no laboratório de análise de sementes do programa de Pós-Graduação em Ciência e Tecnologia de Sementes, pertencente à Faculdade de Agronomia Eliseu Maciel, da Universidade Federal de Pelotas. Nas condições deste estudo verificou-se que as sementes armazenadas de forma comercial apresentaram maior número de nódulos totais ativos, tanto primários como secundários. O mesmo foi observado para as variáveis massa seca de folhas, vagens, caules, raízes e peso de mil sementes. As diferentes formas de armazenagem de sementes pré-plantio influenciaram diretamente a qualidade e rendimento das plantas, assim como seu desenvolvimento estrutural e fotossintético.
