The soy beans market is adjusting a restructuring since the liberation of Roundup Ready?? (RR) technology by federal government in Brazil. In the latest years, the sector started to increase the internal sales, through the agriculturists consciousness about the seeds, more productive and with higher technology than pirate seeds. However, the seed market, many times is evaluated through empirical numbers that end up not representing the exact tendencies of the sector. This study has as a goal a detailed evaluation of numbers that move this market. For this it was used as a reference basis two documents sent by seed farmers to the MAPA: the relation of fields for seeds production (RC), and the production and seeds business (MP). Both documents are processed by APASSUL according to the term of technical cooperation among MAPA(SEFIA/RS), CSM and APASSUL. The observed notes are about the crops in 2005/2006, 2006/2007 and 2007/2008. The results presented a growth in legal seeds production and business, confirming the growth in the sector.

Seed storage potential is affected by harvesting time, genotype, environment conditions and storage conditions. Maintenance of seed vigor ensures adequate crop establishment with high agronomic performance. Thus, the present study aimed to evaluate the reduction in vigor of soybean seeds in relation to the location and storage period. Three experiments were conducted with soybean varieties: BMX Apolo RR; BMX Pot??ncia RR and 53 RR FUNDACEP. The seeds were obtained in the field, soon after reaching reproductive R7, being dry, threshing by hand, placed in paper bags and stored in a refrigerated environment, environmental conditions and at 30??C and relative humidity of 70%. Analyses were performed monthly to monitor the physiological quality of the seeds through germination, accelerated aging 41?? C for 48 hours, accelerated aging 42??C for 48 hours, cold test and field emergence. Based on the results it was concluded that: 1) the soybean seed storage at constant temperature of 30??C causes vigor reduction on 60 days storage; 2) loss of vigor is not linearly; 3) the potential storage of soybean seeds under cold conditions is more than 210 days; and 4) soybean seed storage potential depends also on the cultivar.; O potencial de armazenamento das sementes ?? afetado pela ??poca de colheita...

Soybean seed quality is high related with crop production. Seed coat has the function of maintaining this quality, since acts as a modulator of the interactions between the internal and external environment of the seed, controls gas exchange and water to the environment and regulates germination by interfering with the mechanisms dormancy. In soybean seed husk is present lipoxygenase VLXC, which is involved in the temporary storage of nitrogen. Given the above, the objective of this study was to evaluate the expression of the gene coding for the protein VLXC on the tegument of four soybean genotypes at different times of collection after anthesis. The experiment was conducted in greenhouse Station Lowlands of Embrapa Clima Temperado and Laborat??rio de biotecnologia de sementes (UFPel / FAEM) in the city of Cap??o do Le??o - RS, in a completely randomized design with three replications, and treatments arranged in a factorial model.

Brazil increased 9 % the production of soybeans during 2012/2013 crop. Since 2006, the state of Tocantins grow soybeans during a period called sanitary empty as exceptionalism. This production is destined for research or for seed. However, frequentlly, it was observed the presence of green seed at harvest. This release to produce soybean seed during sanitary empty, issued by the Ministry of Agriculture, Livestock and Supply, is due to climate and land conditions found in the municipalities of Lagoa da Confus??o, Duer?? and Formoso do Araguaia. This study was conducted to evaluate the effect of the occurrence in quality of green seeds in soybean seed lots. Four lots of the cultivar M-SOY 8866, medium cycle, produced in Formoso do Araguaia, state of Tocantins (TO) were used in this study. The lots were selected by visual presence of green seed with a 6X magnifying glass. The lots showed 17 %, 36 %, 49 % green seeds and were named respectively Lot 1, 2, 3 and control (lot with no green seeds). Seed quality was monitored through the thousand seed weight, germination in rolled paper with and without preconditioning, the tetrazolium test and the emergency field tests. The experimental design was a randomized complete block design with four seed lots and five replicates and the averages compared by Tukey test at 5 %.

Chlorophyll retention has been affecting soybean seed production, in the savannah (cerrado) region, mainly in the state of Mato Grosso. The consequence of this verification, are the losses in germination and vigor, and consequently losses in establishing an adequate plant population, at seeding. Chlorophyll decay can be affected by the maturation period, drying conditions, climatic conditions, and desiccating chemical agents. The maturation process, besides the importance of degradation from the green pigmentation, has a distinct effect on the production of specific germination enzymes, such as isocitrate lyase and malate syntase, these convert the lipids into soluble sugars. Maturation can also be considered important in reducing chlorophyll s capacity to produce free radicals that cause oxidation damage, these that determine the storage life of seed. Within stored seed, changes occur associated with deterioration, these can be measured through accelerated aging and biochemical reactions. This study was developed with the objective; verify the influence exerted on quality, evaluate adjuvant protocols in determining this quality of seed with chlorophyll retention. Green seed demonstrated lower germination, viability and vigor, less uniformity in seedlings...

In recent years, for most agricultural species, has increased the use of hybrids by to its high yield and other qualities that put them in front of varieties. In the genus Brachiaria hybridization has been accomplished through the use of crossing B. ruziziensis, that is sexual, and other species of the genus mainly apomictic B. brizantha and B. decumbens. However, hybrids of Brachiaria obtained until now are interspecific and have low seed production, factor limiting the spread of the same, because the convenience and lower cost of implementation / renewal of pastures using seeds instead of seedlings. In the search for the reason that low seed production, this work was to verify the existence of genotype-environment interaction in seed production of hybrid genotypes and seed production potential of these genotypes with reference to cv. Marand??. In a first study, we sought to verify the influence of temperature on the male gamete of five interspecific hybrids of Brachiaria (HBCG348, HBCG011, HBCG148, HBCG450 and HBCG148) and a second study evaluated the viability of pollen and seed production of these same genotypes in different environmental conditions. It was concluded that: a) the temperature factor affect the pollen viability of hybrids; b) the pollen viability of hybrids HBGC348 and HBGC148 is inversely proportional to the temperature rise; c) all the hybrids studied have floral abnormalities that affect the spread of pollen and subsequent seed production; d) were studied the hybrid genotype interaction with the environment; and e) none of the hybrids studied has the potential to produce seeds that credentials to sign in seed-bed market.; Nos ??ltimos anos...
