Abstract:
This issue of Seed Science and Technology contains a number of interesting papers worth giving additional attention. There are five papers that deal with analysis and breaking of seed dormancy, an important issue, not only for commercial practice and breeding, but also for regeneration of habitats and safeguarding bio- diversity. One paper in this issue describes how mucilage production by seeds can aid in overcoming drought stress during germination of seeds from a desert plant. Combatting seed borne diseases remains an important issue. One paper describes how treatment with a combination of two fungicides proved to be effective against seed transmitted seedling blight in Norway spruce. Another paper demonstrates a method to combat a seed- transmitted bacterial infection with watermelon in the seedling stage. Seed vigour tests are needed to give a better estimation of differences between seed lots regarding field emergence. A faster vigour test for tobacco seeds is proposed in a paper in this issue. Even traditional ISTA germination tests may be improved, as demonstrated in a paper for spinach seeds, where especially large seeds can be sensitive to a high moisture level in the tests. Instruments initially used in high-technology industries or in medical care sometimes find their way to seed science applications. An example described in this issue is the use of 3D X-ray computed tomography, which enables rapid non-destructive analyses of the morphology of individual seeds, which can be correlated with germination behaviour. Another paper is on the use of multispectral imaging for seed purity analysis with alfalfa seed lots.

Abstract:
Stavropol region is well known zone of vegetable seed production from 70th years of last century. Development seed production of main vegetable crops is connected with using of new technologies. New technological methods and its influence on the seed yield formation and on the quality of carrot seeds have been investigated in this study. The objects of the study were seeds of carrot variety Marlinka and different technological methods, including in schemes of sowing. Methods and conditions of experiments have been written in details with scheme of experiment by the study influence of sowing schemes on the seed productivity of carrot plants variety Marlinka. Years of study (2015-2017) have been characterized as drought. Seedling capacity of seeds was very small (about of 30%). Sowing with seed drill Matermacc (by the scheme of sowing: 25+20x20x20x20x20+25 sm) ensured the seedling capacity needed for survive of plants after winter. Yield of seeds was in 4-6 time higher in variant with using seed drill Matermacc and scheme of sowing 25+20x20x20x20x20+25 sm, than in variants with traditional technologies. Mass of 1000 seeds was similar under different technologies and schemes of sowing. But seedling capacity was significantly decreased under traditional technologies and using seed drill SZ-5,4.

Abstract:
In developing countries, the use of True Potato Seed (TPS) technology offers some potential economic and biological advantages compared to using seed tubers. One problem with using TPS technology is the lack of seedling vigor, poor germination and non-uniformity of seedlings derived from TPS. Open-pollinated true seeds were divided into three classes based on differences in embryo morphology. Highly significant differences were observed among these seed classes for 100-seed weights, percent germination, rate of germination, 10-seedling weights and percent seedlings with leaves unfurled, ten days after sowing. Seed classes were quantified in terms of 100-seed weight with Seed class 1 having the lowest weight and Seed class 3 the highest; A significantly high r value (0.99) was obtained between seed classes and 10-seedling weight. High r values (0.93) and (0.94) were also obtained between seed classes and percent germination and percent seedlings with unfurled leaves, respectively. Results indicate that it may be possible to use these differences on embryo morphology as a basis for selecting vigorous true potato seeds.

Abstract:
The quality of rice seed is very important for rice production. In the process of rice seed production, seed drying is an important link in the whole process of seed quality control, and the problems in mechanical drying are important factors affecting the quality of rice seed. It is easy to encounter rain weather when the sterile seeds are dried by natural air, which seriously affects the seed vigor. High-quality rice seed is an important guarantee to achieve high yield of rice, and seed germination rate is one of the factors directly affecting rice yield. The drying process has the greatest effect on the quality and germination rate of sterile rice seeds. Selecting reasonable drying technology is an important means to ensure the germination rate of sterile rice seeds. In this paper, the dewatering and drying technology of rice sterile line seeds in intelligent baking room was studied. An adaptive integral sliding mode control algorithm based on Smith prediction was proposed for intelligent baking room temperature. The lag in the system was compensated by Smith prediction; the uncertainty of the system model and the complex interference under variable operating conditions were overcome by the robustness of sliding mode control. And the chattering of the sliding mode was eliminated by the adaptive integral sliding mode surface. The seeds of three rice varieties were dried, the drying dehydration rate, seed germination rate, and seed vigor were measured, and the changes of seed moisture and temperature during drying were observed. The results showed that there was little difference in the seed vigor after drying and air dried, which proved that the dryer could be used to dry different kinds of male sterile seeds. Compared with air dried seeds, the germination rate and germination potential of all mechanically dried seeds have little difference, and the overall difference of germination index and vitality index is also small. This study solved the problem that the seeds of male sterile lines could not be dehydrated and dried in time of rainy weather, which is of great significance to improve seed quality and economic benefits.

Abstract:
Seed health is one of the important factors in maintaining seed quality. This factor is very influential both during seed storage, plant growth in the field, and production to be produced. Seed can be one of the effective media in the spread of plant diseases. With the consideration that pathogenic seed transmission plays an important role in the spread and development of epidemic diseases in some commodities, then gradually seed health tests need to be incorporated into the seed certification process. Seed health testing is required to detect the presence of pathogens or seed health status. To support the program of activities of the Ministry of Agriculture in the development of local rice, it is necessary to start by evaluating the health of seeds in the local paddy varieties. The purpose of the research includes detecting the type of pathogens carried by local varieties in several provinces and inventories of pathogen data carried by local varieties of rice seeds circulating in several provinces. The research method was conducted by taking samples directly from the field and conducting DNA isolation by PCR test to detect bacteria Xanthomonas oryzae pv oryzae (Xoo) and Burkholderia glumae (BG) as well as the growth of pathogen samples in the laboratory. The results of identification are known some seeds detected bacteria Xanthomonas oryzae pv. oryzae (Xoo) and Burkholderia glumae (BG)) which is characterized by the emergence of DNA bands PCR amplification results in positive control according to DNA Ladder. The results of the identification of pathogenic fungi, known the presence of fungi causing blast disease (Pyricularia oryzae) in the overall example of rice seeds tested (47 examples of local rice seeds upland and local swamp) and there are 15 examples or 32% infected with a percentage of infections 0.25 - 14.75%. While result identification of nematodes, known the presence of parasitic nematode Aphelenchoides besseyi on the overall sample of local rice seeds tested (42 examples of local rice seeds upland and local swamp), with 25 examples or 59.5% infected with an infection range of 1-44 specimens.

Abstract:
The article considers the possibilities of using classical, progressive in the food environment container systems of grain harvesting in the seed production environment. The individual ability of such systems to combine technological operations without inter-operational transshipment of material is taken as a basis analytically, technologically, calculatively. As a feature the need to maintain its viability throughout the entire billet cycle without losses is taken into account analytically, technologically, calculatively. General issues analytically, technologically, and computationally take into account the negative impact of the presence of wheeled vehicles in the field with gross seed collections of up to 400 tons, the volume of a single feed of up to 4.2 m3 and marked personnel shortages by calculatively minimizing operators. It is analytically established, today there is no device that fully meets these requirements, in which either the requirement of combining technological operations was not met, or traumatic drying methods for breeding seeds were used, or there were structural difficulties in cleaning the body and low-intensity drying of grain. The result is a replacement drying and transport body for inclusion in the technology of the harvesting and transport process and post-harvest grain processing. The total operational economic effect: from the introduction of drying and transport removable bodies instead of the classic dump truck transport body, with a gross grain harvest of up to 400 tons, ranged from 4.7 thousand rubles/ha to 5.82 thousand rubles/ha - on average, this is 1.76 times lower, or 16% lower than the cost of using transport bodies installed on the “Multilift" system, but not having the ability to combine operations.

Abstract:
This article mainly introduces the necessity of the emergence of functional foods and the current market development. Using chia seeds as the characteristic raw material, adding apple juice and hawthorn juice, it is developed to be suitable for subhealthy people, obese people, diabetes and cardiovascular patients.Functional beverages refer to beverages that regulate human body functions to a certain extent by adjusting the composition and content ratio of nutrients in the beverage. In recent research hotspots, chia seeds are often developed and applied by nutritionists or other nutrition enthusiasts because of their rich nutritional value. Chia seeds are rich in a variety of unsaturated fatty acids, accounting for about 80% of the total fatty acid content, of which omega-3 and omega-6 unsaturated fatty acids are the most content, 68% is α-linolenic acid, which is the most abundant omega-3 fatty acid content of the food. Each 100g of chia seeds contains about 16-25g of protein and about 26-40g of dietary fiber, including all 8 amino acids needed by the human body. In addition, it is also rich in vitamins and minerals, as well as a variety of natural antioxidant ingredients, with high-quality antioxidant functions. This makes the ability of chia seeds to maintain blood sugar stability, protect the heart, cerebrovascular, and promote gastrointestinal motility and bone health cannot be underestimated.Hawthorn contains a large amount of vitamin C, carotene, organic acids and other nutrients, combined with cellulose, pectin and organic acids in apples, can further assist chia seeds to improve gastrointestinal conditions and promote gastrointestinal motility, while soluble fiber Vegetarian can regulate blood sugar.This article chooses apple and hawthorn as flavor bases, oligosaccharides (FOS) as sweeteners, resistant starch and guar gum as composite stabilizers, to produce a chia seed functional drink to reduce weight and improve heart and brain Vascular health problems. In the extremely poor analysis of the orthogonal test results of the chia seed functional drink, the best sample formula.

Thesis (M. Tech. Agriculture) -- Central University of Technology, Free state, 2012
A series of incubation studies and greenhouse experiments were conducted to evaluate the use of EM seed treatments, at different application levels, handling techniques and soil conditions on germination and seedling vigour of selected cultivars of maize, sorghum and sunflower. Two incubation studies were conducted to evaluate the germination and seedling vigour of maize, sorghum and sunflower seeds treated with M-EM from three different suppliers, multiplied at two different ratios (1% and 3%) and diluted at three different levels (0.01%, 0.1% and 1.0%) compared to a control treated with pure water. Results revealed no significant differences under optimum germination conditions, while seedlings under cold stress indicated that M-EM treatments positively affected germination and seedling vigour compared to the control treatments. Two incubation studies were also conducted to evaluate the germination and seedling vigour of maize, sorghum and sunflower seeds treated with M-EM from three different suppliers, multiplied at two different ratios (1% and 3%) and exposed to the influences of irradiation and temperature fluctuation. From the results became clear that the correct storage and handling is essential in optimizing the effect of M-EM on seeds. Even though M-EM was exposed to irradiation and temperature fluctuation, M-EM still had positive effects on germination and seedling vigour. Pot experiments were conducted to determine the effect of EM as seed treatment, at different dilutions, on germination, seedling vigour and dry mass of maize, sorghum and sunflower at different planted depths. Germination were not affected by the M-EM treatment, while shoot length results indicated that seed treated with M-EM could have significant effect on seedling survival. A greater effect was visible on the shoot length of shallow planted seeds, than on deeper planted seeds. From the results no single company, ratio or dilution could be prescribed as paramount. To further investigate the effect of M-EM subjected to the influences of irradiation and temperature fluctuation; maize, sorghum and sunflower seeds were treated with M-EM from three different suppliers, multiplied at two different ratios (1% and 3%) and exposed to the influences of irradiation and temperature fluctuation and planted in soil. M-EM treatments only benefited the germination of deeper planted sorghum seeds compared to the control treatments. The shoot lengths of deeper planted maize and sunflower seed were positively increased by the M-EM treatments while also resulting in significant results for the overall shoot length of sorghum. The third pot study was conducted to determine the influence of EM as a seed treatment on maize, sorghum and sunflower planted in three different soils, namely: sterilized soil, soil treated with M-EM and Fusarium containing soil. Germination and seedling vigour results of the sterilized and M-EM treated soil revealed to be superior to that of the Fusarium containing soil. From the results was concluded that M-EM treatments will probably improve early seedling growth of maize, sorghum and sunflower compared to untreated seed and that M-EM seed treatment and a pre-plant EM soil treatment might assist seeds in unfavourable germination and growth conditions.

Objetivou-se com este trabalho determinar a qualidade física e fisiológica de dez lotes de sementes de Acacia mangium Willd provenientes de plantios comerciais com diferentes idades estabelecidos na savana de Roraima. Os frutos foram coletados de plantios localizados na Serra da Lua, nos municípios do Cantá e Bonfim, de plantas com 4, 5, 7, 9 e 10 anos de idade. As sementes das cinco idades, após a determinação da massa de 1000 sementes, foram classificadas em pequenas e grandes, formando 10 lotes de sementes. O teste de germinação foi realizado, após a superação da dormência, em quatro repetições de 50 sementes, por lote, sobre papel de germinação e mantidos em gerbox a 25C. A embebição foi observada nos tempos 0, 1, 3, 5, 8, 12, 16, 24, 48, 60, 72, 96 e 120 horas para sementes colocadas entre papel. O teste de envelhecimento acelerado foi conduzido em gerbox, em quatro repetições de 50 sementes, mantidos em BOD a 41C por 0, 24, 48 e 72 horas. O teste de condutividade elétrica foi realizado com sementes sem e com a superação da dormência, em quatro repetições de 50 sementes imersas em 75 mL de água por 24 horas. As sementes de A. mangium não apresentam o padrão trifásico de absorção de água em 120 horas após a superação da dormência. Sementes pequenas de acácia, após a superação da dormência, absorvem mais água e apresentam maior média de porcentagem e velocidade de germinação inicial e menor tempo médio de germinação que sementes grandes. A exposição de sementes de A. mangium por 24 horas no envelhecimento acelerado reduz a porcentagem e velocidade de germinação e aumenta a porcentagem de sementes mortas e de plântulas anormais. A imersão das sementes em 75 mL de água por 24 horas a 25C resultam em valores de condutividade elétrica sem relação com a germinação. A idade da planta não apresenta relação com a massa de 1000 sementes e com a absorção de água em 120 horas, para sementes submetidas à superação da dormência. Sementes de plantas com 10 anos apresentam maior porcentagem e velocidade de germinação que sementes de plantas com 4 anos de idade.
The objective of this work was determinate the physic and physiologic quality of ten lots of Acacia mangium Willd. from different commercial established plant ages in Roraimas savanna. Fruits were collected from plantations in Serra da Lua, in Cantá and Bonfim, from plants with 4, 5, 7, 9 and 10 years-old. Seeds from five plant ages, after the determinations of 1000 seeds weight, were classified in small and large, composing 10 lots. Germination test has been done, after dormancy overcoming, in four repetitions with 50 seeds, per lot, above germination paper and inside gerbox in 25C. The imbibition was observed in the times 0, 1, 3, 5, 8, 12, 16, 24, 48, 60, 72, 96 and 120 hours to seeds put between papers. The Seed aging test was made in gerbox in four repetitions with 50 seeds, maintained in BOD in 41C for 0, 24, 48 and 72 hours. The electrical conductivity test was made to seeds without and with dormancy overcoming, in four repetitions with 50 seeds immersed in 75 mL of water for 24 hours. Seeds of A. mangium do not exhibit the three-stage water absorption process in 120 hours, after dormancy overcoming. Small seeds of acacia, after dormancy overcoming, absorb more water and show higher mean of percentage and speed of initial germination and lower time mean of germination than large seeds. Exposition the A. mangium seeds for 24 hours in seed age test reduces the percentage and speed of germination and increases the percentages of dead seeds and abnormal seedlings. The immersion of the seeds in 75 mL of water for 24 hours in 25C results in value of electrical conductivity with no relation to germination. The plant age do not show relation to 1000 seeds weight and to water absorption process for 120 hours, from seeds submitted to dormancy overcoming. Seeds from plants with 10 years-old show higher percentage and speed of germination than seeds from plants with 4 years-old.

Abstract:
Uma das técnicas de restauração ecológica de vegetação nativa testada é a semeadura direta ou plantio de sementes, que pode diminuir custos, facilitar a implantação e a adaptação rápida da espécie ao ambiente comparando ao plantio de mudas. Porém, essa técnica não suplantou o plantio de mudas e um dos questionamentos é sobre abaixa germinação das sementes e do desconhecimento das práticas adequadas de semeio. Portanto, nessa pesquisa avaliaram-se a qualidade, características e desempenho de sementes de cinco espécies florestais nativas, testando também algumas técnicas de semeio no campo. As sementes utilizadas são de espécies arbóreas de recobrimento: Croton floribundus, Croton urucurana, Guazuma ulmifolia, Solanum granulosoleprosum e Trema micrantha de dois lotes (um comprado no mercado e outro colhido pelo pesquisador no campo).A qualidade dessas sementes foi determinada por meio dos parâmetros físicos: pureza, teor de água, massa de mil sementes, largura, comprimento, área, circularidade, cor (sistemas RGB e banda G), peso e densidade aparente; fisiológicos: a velocidade e a taxa de emergência das plântulas e sanitário: avaliação dos fungos presentes nas sementes. Métodos para o beneficiamento dos lotes de sementes, a partir dos parâmetros físicos foram testados. E foram avaliadas a profundidade de semeadura e a emergência das plântulas das sementes tratadas e não-tratadas através do priming, testados em laboratório e em campo. A caracterização física dos lotes (comprado e colhido) foi semelhante (pureza e teor de água), as outras medidas físicas foram em geral diferentes entre os lotes e geralmente maiores para o lote colhido, e apenas para a G. ulmifolia o lote comprado foi superior. Fisiologicamente, os lotes (comprado e colhido) foram similares, porém o lote de G. ulmifolia comprado e de T. micrantha colhido emergiram mais, e as demais espécies foram semelhantes. O mesmo pode-se afirmar para o índice de velocidade de emergência das plântulas (IVEP), que também foram semelhantes entre os lotes, mas não para TMEP (Tempo Médio de Emergências das Plântulas). Para sanidade, os lotes colhidos obtiveram menor incidência de fungos fitopatogênicos. A densidade aparente foi a variável mais correlacionada com a emergência das sementes. Já as melhores profundidades de semeadura foram de 1 cm para a S. granulosoleprosum, 2 cm para a G. ulmifolia e de 1-2 cm para as demais espécies. O priming foi significativo, em laboratório, para C. floribundus em emergência, IVEP e TMEP, e T. micrantha em IVEP. Em campo, o priming reduziu o TMEP de C. floribundus e de T. micrantha, e melhorou o IVEP desta. As espécies mais recomendadas para semeadura direta a partir da emergência em campo são: S. granulosoleprosum >C. floribundus >G. ulmifolia >C. urucurana >T. micrantha. O monitoramento de emergência das plântulas pode ser realizado em 50 dias para S. granulosoleprosum, 65 dias para T. micrantha e 30 dias para as demais. Concluem-se que os lotes (comprados ou colhidos) são adequados, o uso da densidade aparente é o melhor método de beneficiamento e não houve benefícios significativos com o priming. Essas práticas podem ser empregadas em semeadura direta em restauração ecológica.
One of ecological restoration techniques for native vegetation tested is the direct sowing or planting seeds, which can lower costs, easy deployment and rapid adaptation of species to the environment compared to planting seedlings. However, this technique does not supplanted the planting of seedlings and one of the questions is on the low germination of native species and the lack of best practices of sowing. Therefore, in this study it was evaluated the quality, features and performance of five native species seeds, also testing some sowing techniques in the field. The seeds used were tree species filling, Croton floribundus, Croton urucurana, Guazuma ulmifolia, Solanum granulosoleprosum and Trema micrantha two lots (one purchased in the market and another collected by the researcher in the field). The quality of these seeds was determined by the physical parameters: purity, water content, mass of thousand seeds, width, length, area, roundness, color (RGB systems and G band), weight and specific gravity; Physiological: the speed and the emergence rate of seedlings and health: assessment of fungi present in the seeds. Methods for processing of seed lots, from the physical parameters had tested. And it evaluated the depth of sowing and seedling emergence of seeds treated and non-treated by priming, tested in laboratory and on field. Physical characteristics of the lots (purchased and harvested) was similar (purity and water content), other physical measurements were generally different between lots and generally larger for the lot harvested, and only for the G. ulmifolia purchased lot was higher. Physiologically, lots (purchased and harvested) were similar, but G. ulmifolia purchased lot emerged more and T. micrantha harvested lot was better, and the other species were similar. The same said for the seedling emergence speed index (SESI), which were also similar between lots, but not for MTES (Mean Time Emergencies of Seedlings). For sanity, lots harvested was lower incidence of pathogenic fungi. The specific gravity was the most correlated variable with the emergence of seeds. Already the best sowing depths were 1 cm for S. granulosoleprosum, 2 cm to G. ulmifolia and 1-2 cm for other species. The priming was significant in the laboratory for C. floribundus in emergency, SESI and MTES, and T. micrantha in SESI. In the field, the priming reduced the MTES for C. floribundus and T. micrantha, and improved SESI this. The most recommended species for direct sowing on field in emergency are: S. granulosoleprosum>C. floribundus>G. ulmifolia>C. urucurana>T. micrantha. The emergency monitoring of seedlings can be done in 50 days for S. granulosoleprosum, 65 days for T. micrantha and 30 days for the other. To conclude that lots (purchased or harvested) are suitable, the use of the specific gravity is the best processing method and no significant benefits with priming. These practices may be employment in direct sowing in ecological restoration.

O presente trabalho foi desenvolvido para investigar os impactos mecânicos sofridos pelas sementes de duas variedades de feijão vigna (Cedinha e Rabo de Tatu) com dois teores de umidade (13,5% e 7,3% b.u.) ao passarem pelas operações impostas depois da colheita, debulha e pela UBS e suas consequências no decorrer do armazenamento. Foram utilizadas as sementes com pureza acima de 95%, as quais foram submetidas às operações da UBS. Ao longo do sistema de operação foram coletadas amostras para analisar e verificar os danos devidos aos impactos mecânicos. As amostras de trabalho foram logo submetidas aos testes de germinação e aos diferentes testes de vigor. E, em seguida, outras amostras foram armazenadas nas condições ambientais de Alagoinha - PB, e nas condições controladas de câmara seca em Campina Grande - PB. As sementes com a umidade 7,3% da variedade Rabo de Tatu são mais susceptíveis a quebra ocasionada pelos impactos durante o processo de beneficiamento; as sementes das duas variedades estudadas, demonstraram ante o tempo de armazenamento, os impactos sofridos e os teores de umidade iniciais, tendências e um mesmo comportamento, embora quantitativamente diferentes e que os impactos sofridos pelas sementes na UBS durante o seu beneficiamento não exerceram efeitos imediatos sobre a germinação e o vigor das sementes. O teste de vigor que melhor correlacionou com o teste padrão de germinação (TPG) foi o índice de velocidade de emergência (IVE), com um coeficiente de correlação acima de 97%, podendo ser empregado na avaliação do vigor dessas sementes.
In the processing of seeds, soon after the crop and it thrashes, these are directed tha Plant of Improvement of Seeds, where through elevators the machines of before-cleaning, cleaning, separation and classification, treatment, packing and storage are led. This work was developed to investigate the mechanical impacts suffered by the seeds of two varieties of bean vigna (Cedinha and Rabo of Tatu) with two moisture contents (13,5% and 7,3% w.b.) to the they go by the operations imposed after the crop and it thrashes and your consequences in elapsing of the storage. The seeds were used with purity above 95%, so that it could submit them the operations of Plant of Improvement of Seeds. In each operation place samples were collected to analyze and to veriíy the damages happened through the impacts. The work samples were soon submitted to the germination tests and the different vigor tests. And, soon after, other samples were stored in the environmental conditions of Alagoinha - PB, and in the controlled conditions of camera it evaporates in Campina Grande - PB. The seeds with the humidity 7,3% of the variety Rabo de Tatu are more fragile the break caused by the impacts during the improvement process; the seeds of the two studied varieties, demonstrated in the face of the time of storage, the suffered impacts and the initial humidity tenors, tendencies and a same behavior, although with different amounts although with different amounts and that the suffered impacts for the seeds during your improvement didn't exercise immediate effects on the germination and the vigor of the seeds. The vigor test that best correlated with the standard test of germination it was the index of emergency speed, with a correlation coefficient above 97%, could be used in the evaluation of the vigor of those seeds.

The growing demand of consumer markets for seed quality and safety to the producer and consumer is ordering from the production sector a continuous adaptation. Food safety has become an important attribute of food quality. The traceability is in line with this view, since it integrates the entire production chain in a monitoring and certification system. Traceability programs for the productive chain are essential for logistics and management of seed production. The aim of this study was to develop and validate an efficient and effective traceability system for seed production, through a scheme of software, in order to ensure the quality and safety of the products obtained, as well as an important management tool, making the productive chain more competitive in the market. In addition to an extensive literature review, it was also made a partnership with the company Checkplant Traceability Systems LTD, in order to assist in the software scheme that they have already developed for fruit producers and many others. Furthermore, interviews with companies, researchers and seed producers from the south region helped to collect necessary data for the proposed software and to understand the obstacles and critical points of the productive chain. It was presented and tested with the users, the system screens which can work for them, containing the field part (record of field activities, its settings and reports) and the post-harvest stage (record of the activities in the Seed Processing Unit, reports, etc.), paying attention to what should be enhanced to the system implementation. It was observed that the proposed system, based on what happens with fruit producers, it is perfectly adaptable and feasible for seed producers, ensuring, besides of traceability, an important management tool.
A crescente exigência dos mercados consumidores por sementes de qualidade e com segurança ao produtor e consumidor vem ordenando ao setor produtivo uma contínua adaptação. A segurança dos alimentos tem se tornado um importante atributo de qualidade alimentar. A rastreabilidade vem ao encontro com esta perspectiva, uma vez que integra toda a cadeia produtiva em um sistema de monitoramento e certificação. Programas de rastreabilidade para as etapas da cadeia produtiva são essenciais para a logística e o gerenciamento da produção de sementes. O objetivo deste estudo foi propor e validar um sistema eficiente e eficaz de rastreabilidade para a produção de sementes, por meio de um esquema de software, a fim de assegurar a qualidade e segurança dos produtos obtidos, além de uma importante ferramenta de gestão, tornando a cadeia produtiva mais competitiva no mercado. Além de extensa revisão bibliográfica, foi feita também parceria com a empresa Checkplant Sistemas de Rastreabilidade LTDA, afim de auxiliar no esquema de software que os mesmos já desenvolvem para produtores de frutas e tantos outros. Além disso, entrevistas com empresas, produtores e pesquisadores de sementes da região Sul ajudaram para a coleta de dados necessários para a proposta do software e, para entender os entraves e pontos críticos da cadeia produtiva. Foi apresentado e testado junto aos usuários as telas de sistema que podem funcionar para os mesmos, constando a parte de campo (registro de atividades de campo, suas configurações e relatórios) e a etapa pós-colheita (registro das atividades na UBS, relatórios, etc.), prestando atenção ao que deve ser aprimorado para implementação do sistema. Observou-se que a proposta de sistema, baseado no que ocorre com os produtores de frutas, é perfeitamente adaptável e viável para produtores de sementes, assegurando, além da rastreabilidade, em si, uma importante ferramenta de gestão.

Abstract:
The complexity of industrial internet of things devices increases since new network protocols should be incorporated while still maintaining backward compatibility with existing protocols. When the complexity of the devices increases, the need for testing also increases, which can be performed using fuzz testing. Fuzz testing is a highly automated testing technique that has developed to become a fast and efficient way of detecting bugs in different systems, including network protocols. In this thesis, a complete fuzz testing framework is developed, which considers and motivates both the choice of seed selection strategy and the choice of fuzzer. The system under test used in this thesis is an implementation of the Modbus protocol provided by a company called HMS Networks, designed to run on an industrial internet of things device. The fuzz testing framework is used to evaluate the performance of the unweighted minimal set seed selection strategy originally presented elsewhere by comparing it to the afl-cmin strategy and selecting seeds at random. The results obtained when comparing the seed selection strategies contradict the earlier results in five out of six cases, making it interesting to perform further experiments to allow stronger conclusions to be made regarding the performance of the unweighted minimal set strategy.

Abstract:
Spotted knapweed (Centaurea stoebe L.) is a deeply taprooted perennial forb infesting millions of hectares of rangeland in western North America. Spotted knapweed forms large monocultures, which lowers plant diversity, reduces livestock and wildlife forage, and increases surface water runoff and sediment yield. It can produce 5,000-40,000 seeds m-2 year-1, and often produces new flowers after prescribed sheep grazing or mowing defoliates spotted knapweed plants during the bolting or flowering stage. Research has yet to determine if new flowers produced following spring/summer defoliation produce viable seeds by the end of the growing season. The purpose of this 2-year study was to determine the appropriate timing(s) or combination(s) of timings of defoliation on spotted knapweed to reduce viable seed production. Ten spotted knapweed plants, located on spotted knapweed-infested rangeland in west-central Montana, were hand-clipped for each of the following treatments: 1) 35-40% relative utilization of above-ground biomass when plants were in the bolting stage; 2) 100% of buds removed at late-bud/early-flowering stage; 3) 100% of flowers removed at full-flowering stage; 4) Treatment 1+Treatment 2; 5) Treatment 1+Treatment 3; 6) Treatment 2+Treatment 3; 7) Treatment 1+Treatment 2+Treatment 3; and 8) unclipped control. The number of buds/flowerheads per plant, number of seeds per plant, percent viability of seeds, and number of viable seeds per plant were determined when seeds were in the well-developed stage, but seedhead bracts were still tightly closed (mid-August through September). Clipping at any timing or combination of timings reduced the number of buds/flowerheads per plant (P < 0.01), number of seeds per plant (P < 0.01), percent viability of seeds (P < 0.01), and number of viable seeds per plant (P < 0.01) both years compared with the unclipped control. Clipping during the bolting stage reduced the number of viable seeds by nearly 90% compared with no clipping. Clipping during the late-bud/early-flower or full-flower stage reduced the number of viable seeds by nearly 100% compared with no clipping. Defoliation of spotted knapweed via prescribed sheep grazing or mowing in summer should effectively suppress viable seed production of spotted knapweed.

Abstract:
The aim was to determine the impact of Raskila bio-organic preparation on the productivity of winter rape ‘Sunday’ grown under conventional system, in order to activate and save the use of treatment Rovral aqua flo and to improve the wintering of plants. The scientific article presents the data of the conventional winter rape ‘Sunday’ growth intensity, plant formation, accumulation of dry matter, seed quality parameters, fertility data and the influence of the use of bioorganic fertilizers e. winter rape 'Sunday' seeds were coated with bioorganic preparations and synthetic treatments, and additionally sprayed with a bioorganic fertilizer solution. Agrotechnics was carried out according to the technology of winter rape growing at Aleksandras Stulginskis University Experimental station. Additional treatment of winter rape seeds and additional spraying with bioorganic fertilizers had a positive influence on the processes of growth and development of winter rape. By combining seed treatments and treatment with bio-organic Raskila fertilizers (3 l for 100 kg) and spray in autumn (3 l ha-1 ), the best results are achieved: the maximum rape seed yield was 3.87 t ha-1 and the best quality production. Bioorganic fertilizers and treatment Rovral aqua flo has significantly increased the following indicators of winter rape ‘Sunday’: the length of the plant (118.16-127.64 cm), the number of branches (6-10), seeds in the silique (28.27), the seed yield (3.16-3.87 t ha-1). The highest seed yield (3.87 l ha-1) was achieved, applying Nagro preparations in the autumn and the Rovral aqua flo treatment and spraying Raskila plants when the rape reaches a height of 5-7 cm (BBCH 10-19). Premium yield was 86.6 % compared to control. Raskila fertilizers and treatment Rovral aqua flo significantly increased the following parameters of winter rape seeds: content of fat (41.52-43.05 %), proteins (20.39-20.91%), glucosinolates decreased from 18.68 to 18.31 m mol g-1. This has improved seed quality. Treatment with Raskila and treatment Rovral aqua flo decreased seeds and seedlings infestation and morbidity due to Fusarium, Drechlera, Alternaria, Penicillium. Rates of treatment can be reduced if combined with bioorganic fertilizers. Application of bioorganic fertilizers and treatment in combination increases the effectiveness of treatment. Bio-organic fertilizer reduces plant stress caused by synthetic treatment.

Abstract:
For self electrooptic effect devices (SEEDs)1 and for some smart pixels,2 similar devices are used for optical modulators and detectors. Maximizing the contrast ratio or the difference in optical transmissivity (or reflectivity for reflection mode devices3) of the devices in the two states does not give optimum performance because sufficient light must be absorbed in the detector. We calculate the bit rate and signal tolerances for symmetric SEEDs (S-SEEDs) as a function of the absorption coefficients of the devices using a two-state absorption model. To maximize the system bit rate, we show that the optical transmissivities (or reflectivities) for a S-SEED for the two states should be ~58 and 0%. The calculated system bit rate agrees with measured results for a photonic ring counter to within 20%. We also discuss optimum absorptions for logic-SEEDs (L-SEEDs), currently the only demonstrated quantum well smart pixel technology,4 and for SEEDs that have electronic gain.2

Israel, Alvaro, and John Merrill. Production of Seed Stocks for Sustainable Tank Cultivation of the Red Edible Seaweed Porphyra. United States Department of Agriculture, 2006. http://dx.doi.org/10.32747/2006.7696527.bard.

Abstract:
Porphyra species (commonly known as ‘nori’ or ‘purple laver’) are edible red seaweeds rich in proteins, vitamins and other highly valued biogenic compounds. For years Porphyra has been cultured using seeded nets extended in the open sea, and its biomass consumed primarily in the Far East. While demands for international markets have increased steadily at an average of 20% per year, supplies are on the verge and not expected to meet future demands. Alternatively, land-based cultivation of seaweed has become attractive in the mariculture industry since (1) important growth parameters can be controlled, (2) is environmentally friendly and (3) perfectly matches with integrated aquaculture leading to sustainable, high quality products. During the last few years a tank cultivation technology for Porphyra has been developed at the Israeli institution. This technology is based on indoor production of asexual spores and their subsequent growth to 1-2 mm seedlings. The seedlings are then transferred to outdoor tanks and ponds when seawater temperatures drop to 20 °C, or below, and days become shorter during winter time. However, the current technology efficiently serves only about 100 m2 of ponds during one growth season. In order to produce seedlings in sufficient amounts, it is critical to address both technical and biological aspects of seedling production, securing optimal up-scale to commercial-size cultivation farms. We hypothesize that massive production of spores is related to thalli origin, thalli age and sporulation triggers, and that seedling survival and their subsequent growth potential is determined by the seawater quality and overall indoor growth conditions imposed. A series of bio-reactors were constructed and tested in which spore release and spore growth were separately studied. The main assessment criteria for optimal viability of the seedlings will be by determining their electron transport rate using PAM fluorometry and by subsequent growth and biomass yields in outdoor ponds. Altogether the project showed (1), controlled sporulation is possible in big outdoor/growth chamber settings provided initial stock material (small frozen seedlings) is at hand, (2), contamination problems can be almost completely avoided if stock material is properly handled (clean as possible and partially dehydrated prior to freezing), (3), spore release can significantly be enhance using high nutrient levels during thawing for P. yezoensis and P. haitanensis, but not for P. rosengurttii, (4), PAM fluorometry is an efficient tool to estimate growth capacity in both seedlings and juvenile thalli. The BARD funding also served to explore other aspects of Porphyra biology and cultivation. For example, the taxonomical status of Porphyra strains used in this study was defined (see appendix), and the potential use of this seaweed in bioremediation was well substantiated. In addition, BARD funding supported a number of opportunities and activities in the Israeli lab, direct or indirectly related to the initial objectives of the project such as: additional molecular work in other seaweeds, description of at least 2 new species for the Israeli Mediterranean, and continuous support for the writing of a book on Global Change and applied aspects of seaweeds. The technology for Porphyra cultivation in land-based ponds is readily available. This study corroborated previous know-how of Porphyra growth in tanks and ponds, and yet offers important improvements regarding seedling production and their handling for successful cultivation. This study supported various other activities opening additional important issues in the biology/cultivation/use of Porphyra and other seaweeds.

Abstract:
The commercialisation of cocoa production in Ghana has a long history dating back to the nineteenth century. The process of commercial development in cocoa is well documented and provides an alternative mode to contemporary models of commercialisation rooted in the adoption of modern technology and integration of farmers into markets. This working paper critically analyses frameworks for agricultural commercialisation in cocoa through intensification based on the uptake of synthetic inputs and hybrid seeds, by placing agricultural development within a broader framework of the historical development of the frontier in Ghana, and the related problems of ecological and economic crises. The study examines access to land, labour and technology, and how the complex interactions of scarcity of access to physical resources and labour influence farmers’ farming strategies and adoption of technology.
