Item Avaliação da qualidade de sementes de soja produzidas no Oeste Baiano: Empresa Ciaseeds(2019-07-12) Santos, Marília Karine Silva; Viana, Jeandson Silva; http://lattes.cnpq.br/2151004858957292; http://lattes.cnpq.br/8454990292472964Item Qualidade fisiológica de sementes crioulas de feijão-de-corda do Estado de Pernambuco(2019-08-23) Noronha, Sabrina Porto de; Moser, Luciana Maia; http://lattes.cnpq.br/5884448493094899; http://lattes.cnpq.br/7898320104487689The physiological quality of seeds is one of the factors responsible for the good development of the plant in the field. In addition, stress conditions (such as saline and water) during the germination phase can also affect seedling emergence and consequently the vegetative development of crops. Therefore, this work aimed to study the physiological quality of black bean seeds from Pernambuco State. These seeds were supplied by farmers and / or associations of farmers from Agreste and Sertão Pernambuco, the experiments were carried out at the CENLAG Plant Production Laboratory of the Garanhuns Academic Unit. The evaluation of seed biometrics was performed by measuring length, width and thickness. In addition to these parameters, the weight of 100 seeds and the water content were also measured. The physiological quality of the seeds was measured by germination parameters (IVG,% of germination and effect of water and saline stress on germination), as well as seedling length and dry mass. Creole seed samples of string beans from the municipalities of Canhotinho, Sao Joao, Garanhuns, Jucati, Brejinho and Serra Talhada were heterogeneous in color and size. The sample from Garanhuns presented the highest water content (15.05) and the smallest from Brejinho (2.56). In the germination percentage, there was variation using the two parameters (radicle emission and normal seedlings), where the sample of the municipality of Brejinho presented the best germination results (100% considering the radicle emission and 20% considering normal seedlings). Garanhuns and São João samples presented the worst 84% considering radicle emission and 1% considering normal seedlings respectively. The samples that were most affected by water and saline stress in germination and IVG of normal seedlings were from São João and Garanhuns, which did not obtain normal seedlings. Seedling growth was affected by saline and water stress, which caused reduction in shoot and root length, being the most severe salt stress. The seedlings from the Canhotinho sample are the most sensitive to saline stress in relation to shoot length and shoot and root dry mass.Item Caracterização do mercado de sementes forrageiras em Garanhuns-PE(2018-08-27) Macedo, Sthfany Florêncio de; Barreto, Glesser Porto; http://lattes.cnpq.br/7580225824861907; http://lattes.cnpq.br/3451850647557464The cattle farmers' profile has gradually if altered if it observes among them growing concern with the quality of the acquired seeds for the formation of pastures. That change of behavior is associated to the fast technological progress verified in the systems of cattle production. It is noticed that representatives of commercial enterprises of seeds are an important source of information and of knowledge for the consumers / producers, for the resolution of their relative problems to the formation of pastures. The State of Pernambuco is evidencing his/her vocation for the exploration of the livestock, in his/her great majority the livestock is driven by family producers, located mainly in the region of Wild. Most of the area of the state appears for pastoral aptitude handled in those areas. Given that importance, the work had as objective to do a revision on the main aspects related to the quality of seeds of plants forage, as well as to research the market of those seeds (grassy for formation of pastures, leguminous plants, and corn and sorghum for production of silages) in the municipal district of Garanhuns - PE. After the identification of the establishments that you/they marketed seeds forrageiras in the municipal district, it was consisted that there were five stores that sold that type of seeds. It was applied a questionnaire semi-structured then, looking for information regarding the commercialization of the seeds in the year of 2018. The market of seeds of species forage in Garanhuns, in spite of being accomplished by few establishments represents a considerable volume of sale in the year of 2018 it overcame 130 tons of seeds of grassy for the pasture formation. And that the seeds of the gender Brachiaria prevail at the market that corresponds to 71,1% of the total, and being B. decumbens the species more sold at the market with 60.020 kg, corresponding her/it a participation of 46,1% of the whole market. In addition to these, the marketed quantity of corn and sorghum seeds were 50,745 kg for corn seeds and only 5,340 kg for sorghum in Garanhuns, among the cultivars of corn cv. Feroz had greater participation with 33.7% in corn seed market. For the marketing of seed fodder legumes is small only of 450 kg, with only two species sold the estilosantes Campo Grande (Stylosanthes macrocephala and S. capitata) and others just bean seeds-pigeon pea (Cajanus cajanus) demand also is small.
