“…As such, considerable effort has been directed towards maintaining their physiological quality and prolonging their longevity (including monitoring their water content and controlling environmental temperatures and storage conditions) (NAGEL; BÖRNER, 2010). Oliveira et al (2011a) and Silva et al (2011) reported that adequate storage can maintain higher seed viability and vigor than would normally be possible under natural conditions, and the types of packaging materials used, the temperatures and relative humidity of the storage environments play important roles in maintaining seed physiological quality. Oliveira et al (2011b) observed that some species of native Brazilian fruits, the genus Campomanesia (MYRTACEAE), have significant commercial potential due to their desirable agroeconomic characteristics such as high productivity and high brix values.…”

-This article aims at evaluating the effects of different packaging and varied storage temperatures on the germination potential of seeds of Campomanesia adamantium Camb. O. Berg. The seeds were packaged in glass, aluminum foil and plastic containers, or maintained inside intact fruits at 5, 10 and 15 ºC during 0, 7, 14 and 21 days. After these periods the seeds were sown in Germitest® germination paper and maintained in incubation chambers at 25 ºC under constant white light for 42 days. Seed moisture contents were evaluated both before and after storage, as well as germination percentages, germination speed index, root and aerial portion of seedlings lengths, and total dry weights. All possible combinations of packing materials, temperatures and storage times were tested, with four repetitions of 25 seeds for each treatment. C. adamantium seeds showed initial water contents of 31.5%. Glass and aluminum packaging were efficient at maintaining the water content of the seeds, and provided greater germination speed index than the other packaging materials. Germination percentages, seedlings lengths and dry weights did not vary among the different temperatures tested. C. adamantium seeds can be stored for up to 21 days at temperatures between 5 and 15 ºC without altering their physiological quality. In terms of cost-benefit efficiencies, these seeds can be stored without significant damage for 21 days while still inside the fruits at temperatures of 5, 10 or 15 ºC. Index terms: guavira; Brazilian savannah; native fruit; Myrtaceae; seed longevity. CONSERVAÇÃO DE SEMENTES DE Campomanesia adamantium (CAMB.) O. BERG EM DIFERENTES EMBALAGENS E TEMPERATURAS

“…This could be related to increased respiration rate and intrinsic biological factors proper to each seed type (Almeida et al, 1999;Carvalho and Nakagawa, 2012). Experiments with seeds of Copaifera multijuga and Caesalpinia pyramidalis, kept in impermeable packages showed similar pattern in storage (Silva et al, 2011;Oliveira et al, 2011). The analysis of variance for physiological seed quality of quinoa during storage showed that environment (E), packaging (P), period (PE) and the interactions ExP and ExPE had an effect on all observations (p<0.05).…”

Quinoa has grown importance in the world due to the nutritional quality of its grains and crop adaptability to diverse climatic conditions. One problem that limits its cultivation is the reduced viability of seeds during storage and the information is rather scarce. This work aimed at evaluating the physiological quality of quinoa seeds along time when submitted at storage conditions and packaging. An entirely randomized experiment was conducted on factorial scheme 2 x 3 x 6 with four repetitions. The treatments consisted of 2 storage conditions: lab environment and Biochemical Oxygen Demand (B.O.D.) chamber set at 4±2°C and 90% relative humidity (RH); 3 package types: permeable, semipermeable and impermeable; and 6 evaluations: before storage (0), 60, 120, 180, 240 and 300 days after storage. Seed viability was determined by the standard germination test while vigor by accelerated aging test, emergence in sand and emergence speed index. The use of impermeable packaging kept at low temperature maintained the physiological quality of seeds during 300 days of storage. The seeds kept in permeable or semi-permeable packaging under uncontrolled temperature and humidity conditions were viable only for 180 days. The permeable package using kraft paper was the least efficient to conserve physiological quality of quinoa seeds. It was demonstrated that quinoa seeds are rather sensitive to high temperature, loosing viability in short time.

“…Sendo assim, as sementes provenientes da borda toleraram melhor o armazenamento mantendo o poder germinativo por aproximadamente seis meses. Oliveira et al (2011) também estudaram o armazenamento de sementes de P. pyramidalis, sem considerar o efeito borda e concluíram que a viabilidade e o teor de água das sementes foram mantidos durante o período avaliado (225 dias).…”

O objetivo neste trabalho foi avaliar a influência da localização (pasto, borda e interior do fragmento de caatinga) de plantas de P. pyramidalis sobre a produção e armazenamento de sementes. Os frutos foram coletados em 24 matrizes, das quais nove localizadas no interior do fragmento, outras nove na borda e seis no pasto; em seguida, as sementes foram submetidas a três períodos de armazenamento: zero, três e seis meses. Determinou-se a massa fresca total dos frutos mensurando-se 100 frutos quanto às dimensões, número de sementes e condições sanitárias por matriz. O delineamento experimental no armazenamento foi inteiramente casualizado, em esquema fatorial 3 x 3 (localização e períodos) em três repetições. A posição das plantas em relação ao fragmento de caatinga influencia a produção de frutos e sementes de Poincianella pyramidalis, nas condições de Castro Alves, BA, sendo que as plantas isoladas produzem maior quantidade de frutos em referências às localizadas na borda e no interior do fragmento de caatinga, enquanto no seu interior se observa menor incidência de pragas e doenças nas sementes. As sementes provenientes de plantas localizadas na borda do fragmento de caatinga mantêm o poder germinativo durante seis meses de armazenamento enquanto nas sementes de interior e pasto, há redução na porcentagem e na velocidade de germinação.
