“…The soybean Glycine max (L.) Merrill is one of the most important crops in the world due to the scale of its production, driving the economy of many producing countries (Ferreira et al, 2021;Treter et al, 2021). In the last Brazilian harvest (2020/2021), the grain production was approximately 136 million tons.…”

Due to its important participation in the agribusiness model worldwide, soybean actively drives national economies in producing countries. However, biotic and abiotic factors caused by pests and climate changes, respectively, can disrupt its productivity and consequently the business market. For this reason, the development of plants more tolerant to these negative environmental elements has been frequently one of the goals of scientific research. In the pipeline to obtain genetically improved plants, tissue culture protocols often represent a bottleneck, since the efficiency at this stage can be genotype-dependent. Therefore, the objective of this work was to evaluate the root regeneration process of two soybean genotypes (BRS 283 and BRS 537) in four different substrates (vermiculite, sand, medium containing activated charcoal and, control – MS medium and glucose). The rooting development was measured by the root’s length (cm²), dry mass (mg), volume (mm³), surface area (mm²), and diameter (mm). Results showed that in the activated charcoal medium, for both soybean genotypes, roots grew longer and presented a higher dry mass of roots, and root length when compared to vermiculite and sand substrates. We concluded that the efficiency of tissue culture is genotype-dependent since assayed genotypes presented phenotypical responses significantly different. The supplementation of tissue culture medium with active charcoal improved root growth for both genotypes. Therefore, it is likely that this medium can be also successfully applied to other soybean genotypes, or to other crops with similar tissue culture procedures to promote better rooting and plant establishment in further developmental stages.

The adoption of technologies that allow the mitigation of environmental stresses, such as the use of regulators in seed treatment, is an alternative for crops in high temperatures regions. This study aimed to assess the heat stress mitigation on the germination and initial development of carrot seedlings using plant growth regulators. The study was divided into three experiments performed at the temperatures of 25, 30 and 35 °C. A 5 × 3 factorial arrangement was used, with fve carrot cultivars (Alvorada, Brasília, BRS Esplanada, Tellus and Tropical) and two products (Stimulate® and thiamethoxam), in addition to the control (untreated seeds). The following variables were evaluated: germination, first germination count, seedling length and dry mass. When the cultivars had their seeds treated with the plant growth regulators at 25 °C, the germination for the Tellus cultivar was 28 % higher than for the control, while, at 30 °C, the seed germination for BRS Esplanada and Tellus was twice as high as for the control, and showed a higher vigor than that of Alvorada, Brasília and Tropical. Overall, the thiamethoxam promoted increments at the initial development of carrot seedlings at 25 and 30 °C. However, the germination of the carrot cultivars was disrupted at 35 °C.

The objective of this work was to evaluate the performance of soybean cultivars as a function of the application of organomineral fertilizer via foliar, to obtain high yields. The study was conducted at the municipality of Mineiros-GO, Brazil. The soil is classified as neosol quartzeneic ortic typical, with medium texture. The experimental design was a 5x3 factorial, totaling 15 treatments, corresponding to five doses of Potamol Plus® (0, 0.25, 0.5, 0.75 and 1 L ha-1) and 3 cultivars of (M7739, M8372 and TMG7062) in 4 replications. The data obtained was submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model, for these were performed single and multivariate analyzes. The analysis of variance showed that the cultivar factor was significant for all variables. Significance was also observed in the dose factor for APR, LUG, LQG, REN, LDG, GTP and GCP. Interaction between factors (C x D) occurred in APR, LUG, LDG, LQG, LTG, GTP and GCP. Potamol Plus® organomineral fertilizer applied foliar at 30 (50%) and 45 (50%) days after sowing did not increase the productive performance of soybean cultivars M7739, M8372 and TMG7062. The cultivars M7739 and TMG7062 presented high yields (yield ≥ 70 bag ha-1).
