“…Regarding the physiological quality of stored seed, Santos et al (2020) reported that germination is a phenomenon affected by environmental conditions, mainly availability of water, and decreases in germination rates are directly related to presence of microorganisms in the seeds; according to the data presented, the resistance of several fungi was adjusted due to these factors. Costa et al (2020) found that the higher the incidence of Aspergillus sp.…”

Soybean is subject to occurrences of pathogens transmitted by seeds, requiring phytosanitary treatment, however, it can be toxic to humans and the environment. The objective of this study was to evaluate the effect of essential oils of rosemary (Rosmarinus officinalis) and eucalyptus (Corymbia citriodora) on the control of phytopathogenic fungi in stored soybean seeds. The experiment was carried out in a completely randomized design, using a 2 × 5 factorial arrangement consisted of seeds with and without fungal inoculation (Aspergillus flavus and Penicillium rubens) and five seed treatments (three essential oils, positive control, and negative control), with four replicates. Rosemary and eucalyptus essential oils and their combination were applied to soybean seeds at the rate of 4 mL kg-1, at a concentration of 700 µL mL-1. Distilled water with 2% Tween® 80 was used as negative control, and the commercial fungicide Vitavax-Thiram® 200SC was used as positive control, according to the manufacturers’ recommendations. The R. officinalis essential oil was efficient in the control of Penicillium sp. in stored soybean seeds and showed a similar effect to the positive control. The C. citriodora essential oil reduced the incidence of Aspergillus sp. Therefore, these essential oils have potential to be used as an alternative control of soybean seed pathogens.

“…According to Santos et al (2020), fungi of the genera Aspergillus sp., Penicillium sp., and Rhizopus sp. can damage stored seeds, reducing their quality, as these fungi develop in tissues of embryos, causing discoloration and seed rot, thus reducing the seed germination rate and vigor.…”

“…The germination speed index (GSI) in figure 4 shows significant results for the paper roll treatment (6.347). Santos et al (2020), using Cenostigma tocantiunum Ducke, a species belonging to the Fabaceae family native to the Amazon rainforest, and recommended for various uses including land rehabilitation and urban tree planting, found a germination percentage of 85% and a germination speed index (GSI) of 6.59 when using a paper roll substrate.…”

The Pterogyne nitens Tul., popularly known as "amendoim-bravo," belongs to the Fabaceae family and can be used in the recovery of degraded areas and in the restoration of riparian forests. The objective of this study was to biometrically characterize the seeds of "amendoim-bravo" and study the influence of substrates on the physiological potential of the seeds. For biometric characterization, eight replicates of 100 seeds were used to determine length and width. In the germination test using a completely randomized experimental design, the seeds were distributed in five different substrates: paper towel in roll form, between blotting paper, on top of blotting paper, between sand, and commercial substrate, at a regulated temperature of 30°C in a Biochemical Oxygen Demand (B.O.D) chamber. The first germination count (PCG), germination speed index (IVG), root length, shoot length of seedlings, dry root mass, and shoot mass of seedlings were analyzed. Evaluating the first germination count and germination index, the paper towel roll substrate showed superiority with 96% and 98%, respectively, statistically differing from the other treatments. The value for germination speed index also highlighted the use of the paper towel roll (6.347). Regarding mean time, mean speed, and synchrony, the best results were also achieved with the paper towel roll substrate. Pterogyne nitens Tul. seeds have an average length of 11.52 mm and a width of 6.35 mm. For evaluating physiological potential, the use of the paper towel roll substrate is recommended.

“…A sua utilização é diversificada, com destaque para seu uso como lenha, estacas, peças estruturais na construção civil, como caibros, ripas e vigas. Também possui ampla utilização em recuperação de áreas degradadas e em arborização urbana, em decorrência dos aspectos favoráveis como fuste ereto, crescimento rápido, copa frondosa e sistema radicular pouco agressivo (Santos et al, 2020).…”

As espécies arbóreas têm potencial para aproveitamento em diversos setores e cadeias produtivas. Neste contexto, a biometria constitui-se em uma importante ferramenta para identificar as principais características intrínsecas ao fruto e a semente. Portanto, objetivou-se com este estudo caracterizar biometricamente os frutos, sementes e plântulas da espécie Cenostigma tocantinum Ducke, de modo a obter informações sobre a variação das características. Para a avaliação da biometria foram utilizados 100 frutos frescos de diferentes árvores matrizes. As características avaliadas foram: comprimento, largura e espessura de fruto e sementes, peso dos frutos, número de sementes por fruto, emergência de plântulas, comprimento da parte aérea, raiz principal e total das plântulas. Constatou-se variabilidade paras os caracteres biométricos relacionados as dimensões e pesos de frutos de Cenostigma tocantinum. O percentual de emergência das plântulas foi de 98%. Os resultados encontrados nesse estudo podem auxiliar na diferenciação e identificação da espécie, fornecendo dados biométricos de importantes características botânicas e da espécie no estágio inicial do crescimento.
