“…Seedling emergence -normal seedlings emerged on the 26th day after sowing. It was considered as emerged normal seedling those that show itselves healthy, and with part of the hypocotyl visible outside the substrate (Jeromini et al, 2015). The results were expressed as percentage (Brasil, 2013).…”

“…Its seeds have an average water content of 6% (Arantes et al, 2017). However, storage for up to 90 days is recommended, as it is after this period that the germination rate decreases and the seeds lose vigor (Jeromini et al, 2015).…”

Cagaita (Eugenia dysenterica) and Tingui (Magona pubescens) are two species of trees native to the Cerrado, with sociological, economic, and medicinal importance, besides to being used in the recovery of degraded areas. The incidence of plant diseases, as well as the mycoflora associated with their seeds, may represent a possible threat to the survival of the species. The cultivation of trees in the Cerrado Biome, as well as the diseases associated with them, are still poorly studied. The present work aimed to evaluate the mycoflora associated with Cagaita and Tingui seeds, the transmission and pathogenicity of these fungi to plants. The seeds were collected from mother trees located in the municipality of Gurupi and Figueirópolis in the state of Tocantins, Brazil. The blotter-test method was used to evaluate the mycoflora associated with the seeds of both species, with and without asepsis. The fungal incidence per seed was evaluated with the aid of a stereoscopic and optical microscope. The potentially pathogenic fungi identified in the sanitary analysis of the seeds and in the transmission, test were inoculated in the plants in order to confirm Koch's postulates. The transmission test was carried out from non-disinfested seeds until the appearance of symptoms in the seedlings. A total of 11 fungi associated with the seeds of both species were identified. The genus Curvularia showed pathogenicity, causing spots on Cagaita leaves, being also transmitted from seeds to seedlings. The Fusarium genus showed pathogenicity in Tingui seedlings, causing damping-off and wilting. Colletotrichum sp. caused leaf spots on both species and fruit spots on Cagaita.

“…the seed during its storage, this in turn, is directly linked to the temperature and pressure during storage. The type of packaging determines the rate of deterioration and, therefore, in the maintenance of the physiological quality of the seeds, packaging that reduces gaseous exchange and water with environment, reduces the metabolic processes ensuring the prolongation and longer longevity of the seeds during storage (Antonelle et al, 2009;Jeromini et al, 2015).…”

Seed storage is one of the oldest techniques that, besides protecting against attacks of microorganisms and insects, has as main goal to preserve the product, with minimum losses, ensuring vigor and viability of the seeds. Safflower (Carthamus tinctorium L.) is a crop with great agricultural potential due to the high content of oil in its seed and can be a viable alternative in the production of biofuel. The goal of this study was to evaluate the effects of packaging and storage temperatures on the physical and physiological quality of safflower seeds. The experiment was conducted in the soil and plant production and bromatology laboratories of the Institute of Agrarian and Technological Sciences, Federal University of Mato Grosso Campus of Rondonópolis, in the period of July to September 2014. The experiment was a completely randomized design in a 5 × 2 factorial scheme, corresponding to five temperatures (10, 15, 20, 25 and 30 °C) and two packages (cotton and paper) with five replicates. The physical quality parameters (water content in the seed, mass of one thousand seeds, hectolitre weight) and physiological parameters (percent germination, Seed viability (Tetrazolium), accelerated aging and electric conductivity) of the seeds were evaluated. The physical quality of the safflower seed was not influenced by, the types of packaging and storage temperature. The physiological parameters of safflower seeds were significantly altered by the the type of containers and storage temperatures conditions. The paper packaging, at temperatures of 20 and 25 °C, provided greater conservation of the seed.
