title: Enrichment, quality, and productivity of soybean seeds with cobalt and molybdenum applications

description: Abstract: Cobalt (Co) and molybdenum (Mo) are vital nutrients for biological fixation and nitrogen assimilation by soybean. This study aimed to evaluate the increase of Co and Mo contents in soybean seeds by leaf applications. The experiment was carried out in a seed production field in a 3 × 3 factorial scheme with three Co and Mo doses and three treatments (times). Each treatment consisted of two application times: R3+R5.1 (T1), R3+R5.4 (T2), and R5.1+R5.4 (T3). Doses were 0, 400, and 600 g.ha−1 of Mo and 0, 40, and 60 g.ha−1 of Co. No difference was observed for productivity, one thousand-seed weight, and germination. An interaction was observed between dose and application time in the Mo content. The application of 400 g ha−1 of Mo in T1 (R3+R5.1) provided a higher Mo content in the seeds (13.5 g.kg−1), which is 1350% higher when compared to the control. For Co, there was a difference only for doses, and the application of 40 or 60 g.ha−1 of Co increased seed nutrient content by 30%. Therefore, a higher enrichment of Co and Mo was observed in seeds with applications of 40 and 400 g.ha−1, respectively, applied in R3+R5.1.

title: Sodium hypochlorite in the priming of tobacco seeds

description: Abstract: Due to the non-uninform maturation of tobacco fruits and seeds, the priming technique has been used by the tobacco industry as a way of increasing the uniformity and germinations peed of seeds. Several factors can affect priming, including the time and environment in which the treatment is performed. In order to evaluate the effect of sodium hypochlorite as priming agent at different concentrations and the priming period on the physiological quality of the tobacco seeds, it was used a seed lot of commercial cultivar CSC 439 from the Virginia varietal group, widely used by the producing companies. The seeds were subjected to priming in aerated solution at different priming periods (180, 60, 30, 15, and 5 min) and concentrations of sodium hypochlorite (1%, 0.50%, 0.25%, and 0.10 %). The physiological quality was evaluated by the water contents, germination tests, first count, germination index, initial and final stands, emergence index and electrical conductivity. The priming with sodium hypochlorite did not affect germination, but allowed a higher percentage and speed of emergence when using the 1% concentration for 180, 30 and 15 min.

title: Productive performance of soybean plants originated from seed lots with increasing vigor levels

description: Abstract: The objective of this work was to evaluate the productive performance of soybean crops, in response to the use of seeds from lots with increasing vigor levels. The study was developed during the 2014/2015 and 2015/2016crops. In the first period, 14 treatments were evaluated, consisting of two factors, two genotypes (Syn 1059RR and NK7059RR), and seven seed lots. In the second seven treatments were considered, involving one genotype (Syn 1158RR) and seven seed lots. In both crop years, seed lots had vigor levels of 65, 70, 75, 80, 85, 90 and 95%, as determined by the accelerated aging test. The experiment was performed in a randomized block design, with a factorial scheme and five replications. Plant height, yield components, and grain yield were assessed throughout the culture cycle. The reflex of seed vigor in crop performance depended on the genotype employed. Also, there was an increase in both vegetative and reproductive performances of the crop as a function of seed vigor level. In this sense, every percentage point augmented in the vigor level of the lots resulted in a grain yield expansion of up to 28 kg.ha-1.

title: Physiological potential and health of soybean seeds obtained from organic and conventional systems

description: Abstract: The quality of seeds produced is the result of the management practices used and environmental conditions during growing. The aim of this study was to evaluate the physiological potential and the health of soybean seeds produced in an organic and conventional system. The genotypes UEL 110 and 122 and BRS 257 and 284 were tested in organic and conventional systems in a randomized block design. The following characteristics were evaluated: moisture content; thousand seed weight (TSW); germination (G) and first count of germination (FCG); tetrazolium (TZ); classification, length, and dry matter of seedlings; and seed health. Analysis of variance was performed separately for the management systems, followed by combined analysis. When significant, the Tukey test (p&lt;0.05) was applied. Multivariate analysis was performed using R software. There was not significance between genotypes and management systems. The conventional management system performed positively for the characteristics TSW, G, TZ, FCG, classification, and length and dry matter of seedling roots, as well as for plant health. The UEL genotypes obtained higher TSW; UEL 110, lower germination; and BRS 257, a smaller number of ungerminated seeds and higher infestation by Cladosporium spp. The seeds produced under the organic system have greater weight and lower infestation by contaminants, whereas the conventional system produces seeds of better physiological quality and lower contamination by Phomopsis and bacteria. The genotype BRS 257 may have seeds multiplied in the organic and conventional management systems.

title: Gene expression during the germination of coffee seed

description: Abstract: Germination of the coffee (Coffea arabica L.) seed is the result of events that occur simultaneously in the embryo and endosperm. To understand the molecular mechanisms responsible for these events, we undertook a transcriptome analysis of embryo, micropylar and lateral endosperms from 10-day-imbibed seeds. The sequencing yielded contigs coding for 16,813 proteins. From those, 14,005 (~ 83%) were highly similar to at least one protein sequence in the nr database. 162 genes were significantly expressed in the embryo, 36 in the micropylar endosperm and 72 in the lateral endosperm. The tissue specificity analysis of the significantly expressed genes showed that the embryo had the highest proportion of specific genes (113/162, ~70%), while 11 were expressed in the micropylar and lateral endosperms. In the embryo, genes were mainly associated with abiotic stress, cell growth, and intercellular communication. In the micropylar and lateral endosperms, they were associated with abiotic stress and cell wall degradation. The accuracy of RNA-seq data was confirmed by RT-qPCR. This work adds new information about the molecular mechanism involved in coffee seed germination.

title: Physiological and sanitary performance of soybean seeds during storage after phosphine fumigation

description: Abstract: To maintain the physical, physiological and sanitary qualities of soybean seeds during storage, efficient control of pests must be considered. Fumigation is a technique used to eliminate pests that infest stored seeds, but there is no information on possible toxic effects on the seed and the microorganisms in the seeds fumigated several times during storage. An experiment was conducted to ascertain its effect on germination, viability, and vigor (tetrazolium, accelerated aging, and seedling length tests) and on the microorganisms associated with the soybean seeds. The study was conducted on soybean seeds which were exposed to three phosphine fumigations over the period of 210 days of storage in a completely randomized statistical design. The treatments were three concentrations of phosphine (PH3.m-3) at 1.0, 2.0 and 3.0 g.m-3 and the control without application of phosphine, applied three times on the same group of the seeds throughout the storage period. The fumigation chambers were made of plastic sheet impermeable to phosphine gas. Seed fumigation did not modify the physiological performance of the soybean seeds. It also did not affect the viability of the fungi and bacteria in the seeds.

title: Influence of the storage environment on the physiological quality of millet seeds (Pennisetum glaucum (L.) R. Br.)

description: Abstract: Millet is a species of the grass family used in cattle pastures, for hay, for silage, and in soil cover in no-tillage systems. However, studies on seed production and post-harvest techniques for this species have not been sufficiently developed, considering the demand for and potential of this crop. The objective of this study was to monitor the physiological quality of millet seeds stored in porous packaging. Millet seeds were stored under four ambient conditions (natural laboratory environment, dry chamber, refrigerator, and freezer). Physiological quality was evaluated by germination and vigor tests before and during storage each year, up to six years for the dry chamber and natural laboratory environment, and up to 12 years for the refrigerator and freezer. Analysis of variance was conducted on the data, which were in 4 × 6 and 2 × 12 (environment and storage period) factorial arrangements. The means of the environments were compared by the Tukey test (p ≤ 0.05) and the storage periods by regression analysis. The germination capacity of millet seeds is best conserved in a refrigerator and freezer, and they remain viable for up to twelve years of storage under these conditions.
