“…The PMG was higher in the BRS Pérola cultivar and did not oscillate in the three positions of the biostimulant; however, the cultivar BRS Marfim had reduced PMG in the positioning of the biostimulant in R5 and R5 + R8 (Table 4). The increase of PMG with the use of growth regulator in common bean was also observed by Soratto et al (2015) and Pedó et al (2018). However, Abrantes et al (2011), Pavezi et al (2017, Lana et al (2009) and Bossolani et al (2017) did not observed variations in the PMG after the use of the biostimulant in common beans.…”

This study aimed to evaluate the effect of biostimulant positioning on common bean cultivars in the southwestern Goiás conditions. The experiment was conducted in the municipality of Mineiros-GO. The experimental design was a randomized block in factorial 6x3, corresponding to the positioning of the Triplus® biostimulator (R5, R5 + R8 and water) in six common bean cultivars (BRS Campeiro, BRS Esteio, BRS Estilo, BRS Marfim, BRS Notavel and BRS Perola) in 4 replicates. The following productive attributes were evaluated: number of pod, number total of grains, number of commercial grains, number of non-commercial grains, mass of commercial grains, thousand grains mass. There was a significant interaction between cultivar x biostimulant as well as the factors alone. At the end of the experiment, it was concluded that the positioning of the biostimulant via foliar in the R5 phenological phase provided the highest yields for all common bean cultivars, especially BRS Estilo (43.87 sc ha-1) and BRS Notavel (43.02 sc ha-1). Biostimulant applications at stage R5 promoted the best results for number of non-commercial grains, mass of commercial grains, thousand grains mass. In the three stratifications used in the dendrogram, it was possible to form two groups of genotypes. Number total of grains, number of commercial grains and number of pod positively correlate with yield.

“…Regarding seedling dry mass, the best performance was achieved for lot 5, with the lowest value for lot 3 (Table 1). Lots with seedlings exhibiting higher dry mass contents have greater vigor, indicating a greater transfer of dry mass from seed reserve tissue to the embryonic axis (Pedó et al, 2018;Krzyzanowski et al, 2020). Lot 5 also showed superior performance in the cold test, along with lot 6, while lots 3 and 7 had lower performance.…”

The search for techniques that allow for the rapid and accurate assessment of seed vigor, such as the Seedling Analysis System (SAPL®) and ILASTIK®, can be promising alternatives for seedling image analysis. The objective of this work was to classify the vigor of lentil seeds using seedling image analysis techniques and interactive machine learning. Seeds from seven lots were characterized for physiological potential through germination and vigor tests. For computerized seedling analysis, the seeds were subjected to seedling growth tests at 20 °C for three, four, five, and ten days, and then photographed using a digital camera. The images were processed using SAPL® software, yielding values for total length, root length, shoot length, and vigor, growth, and uniformity indices. ILASTIK® provided data on the percentage of vigorous seedlings, non-vigorous seedlings, and dead seeds. The total length of seedlings, root length, shoot length, and vigor indices determined at 4 days of germination by SAPL® allowed for the classification of lots in terms of vigor. Data obtained by ILASTIK® at 4 days of germination, used in machine learning studies, enable the development of models with high accuracy for seed vigor assessment.

“…Adding to the three crops of 2018, the country produced a total of 3,374,079 tons of beans, about 82,767 tons more than the production in 2017 (IBGE, 2018). It is cultivated throughout the Brazilian territory, under different edaphoclimatic conditions, technological and management levels (Tavares et al, 2017;Pedó et al, 2018). However, in the South region, the cultivated area and production in tons have been considerably decreasing.…”

Hydration and cooking of beans leads to significant losses in their nutritional quality, but some genotypes may have a greater resistance to protein degradation. Therefore, this study aimed to evaluate the effect of the genotype on both quality and quantity of proteins available in the beans before and after hydration and cooking. The grains of six landrace genotypes from the Active Bean Germplasm Bank of the UDESC (BAFs: 03, 07, 57, 75, 97 and 102) were used "in natura" (control) and subjected to the following treatments: hydration for 8 hours and hydration followed by cooking. The content and electrophoretic profile of the soluble proteins were evaluated. Initially, the protein content ranged from 39.4 (BAF 57) to 51.1 mg g-1 FW (BAF 75). Hydration provoked a decrease in the protein content for all genotypes, having it been accentuated with the cooking. BAFs 07 and 75 presented a higher protein content after cooking, 29.1 and 31.4 mg g-1 FW, respectively, and concomitantly, higher intensity and presence of protein bands. In conclusion, BAFs 07 and 75 demonstrate a higher resistance to protein degradation and their use may be recommended in crosses aimed at improving the nutritional and technological grain quality.
