“…However, other results indicate better germination and vigor in small and medium sized seeds [16] and other showed no relationship between seed size and seedling emergence and final yield [17]. Also addition of fertilizer to hydroprimed seeds could affect plant growth and yield as shown for sulfur which resulted in an increase in yield in both primed and nonprimed seeds [18]. Soil factors play a role in germination and subsequent yield of a crop.…”

Soybean (Glycine max (L.) Merr.), a good source of protein and oil, is used to produce nutritious isoflavone-rich soybean-based foods. The objectives of this study were (i) to determine the germination difference among soybean seeds in various seed sizes and (ii) to evaluate effects of seed pretreatment on germination and seedling emergence. Six varieties of different seed size class were used: (i) small size (MFS-561 and V08-4773), (ii) medium size (Glen and V03-47050), and (iii) large size (MFL-159 and V07-1897). Pregermination treatments include 0, 5, or 10 hours soaking and germinating/planting with or without nitrogen fertilizer. Large seed size varieties showed low germination rate and N addition caused the least reduction in germination in these seeds during the first 24 hours. While N had no effect on seed germination after 72 hours, growth in N treated seed was low. Seedling emergence was comparable across varieties in 2013 and water priming and N application had no effect. However, while varieties did not differ in final emergence for nonprimed seeds in 2014, water priming led to a high reduction in seedling emergence of large seed varieties in this study. Application of N fertilizer had no effect on seedling emergence in field experiments.

“…Many authors have observed improvement in the physiological quality of seeds when they are under specific stress conditions, such as sub or supra-optimal temperatures, water deficits or high salinity in the medium (Bejandi et al, 2009;Patanè et al, 2009;Pereira et al, 2009;Jisha et al, 2013). Oliveira et al (2010) evaluated water uptake, germination and the initial growth of sorghum seedlings from artificially aged and osmoconditioned seeds under conditions of salt stress.…”

Seed priming, also called osmoconditioning, is one of the most promising treatments for reducing the time needed between sowing and seedling emergence. In addition, this treatment has also been associated with increases in seed tolerance to adverse conditions during seed germination and seedling establishment. Thus, this review examines the major changes seen in abiotically stressed plants as a result of seed priming treatments, in particular physiological and biochemical changes promoted by seed priming. Many studies cited in this review have reported improvements in seed physiological quality and seedling vigour when using seed priming under abiotic stress conditions. These features have been related to the repair and build-up of nucleic acids, increases in the synthesis of proteins, osmotic adjustment mechanisms, the repair of membranes and reduced lipid peroxidation, resulting from enhanced antioxidative activities. However, further studies are necessary to explain how physiological and biochemical changes caused by seed priming improve the plant's adaptations to stressful environmental conditions.

“…Em oleaginosas, Hussain et al (2006) verificaram que a imersão de sementes de girassol durante 24 horas a 27 o C seguida de secagem promoveu aumento na velocidade de emergência das plântulas em condições de campo. Para soja, a imersão em água durante 12 horas a 25 o C, seguida de secagem, e imersão em solução de auxina e giberelina favoreceram a emergência de plântulas e o comprimento das folhas (BEJANDI et al, 2009). Fujikura et al (1993) constataram que em sementes de girassol, a imersão em água por cinco horas a 23 ºC seguida de secagem a 20 ºC favoreceu a porcentagem de plântulas normais a 20 e 30 o C. Já, em algodão, a imersão em água durante 15 horas seguida de secagem proporcionou aumento da germinação, tanto quanto a imersão em soluções com -1,2 MPa (RIBEIRO et al, 2002).…”

RESUMO -A hidratação controlada pode favorecer a germinação e o estabelecimento das plantas de diversas espécies. O objetivo desse trabalho foi avaliar o efeito do condicionamento fisiológico pela técnica da hidratação controlada seguida de secagem na qualidade fisiológica e no estabelecimento de plantas de pinhão manso. Por lote, foi estabelecida a curva de absorção de água pelas sementes. Posteriormente, as sementes foram imersas em água destilada (8 mL g -1 ), secas a 32 o C até atingir teor de água próximo ao inicial e submetidas aos testes de germinação e de vigor (primeira contagem, classificação de plântulas e emergência de plântulas em areia). Em casa de vegetação, as sementes foram distribuídas entre substrato plantmax. De acordo com resultados pode-se concluir que a hidratação promoveu o aumento do comprimento e da massa seca de plântulas e favoreceu a emergência de plântulas de pinhão manso. A sobrevivência das plantas provenientes apenas de sementes de qualidade fisiológica intermediária é beneficiada pela hidratação das sementes de pinhão manso.Palavras-chave: Jathorpha curcas L.

The aim of this study was to evaluate the effect of priming, using a technique of controlled hydration followed by drying, on the physiological attributes and establishment of jatropha plants. The water-absorption curve was established per batch of seeds. Subsequently, the seeds were immersed in distilled water (8 mL g -1 ), dried at 32 °C until a water content close to the initial levels was reached, and subjected to tests for germination and vigor (initial counting, seedling classification, and the emergence of seedlings in sand). In the greenhouse, seeds were distributed in a plantmax substrate. From the results it can be concluded that hydration promotes an increase in the length and dry matter of seedlings, and favors the emergence of Jatropha seedlings. The survival of plants from seeds with only intermediate physiological attributes, benefits from the hydration of Jatropha seeds.
