“…Seeds germination is a physiological and important process in the development of seedlings, which involves complex processes and the use of their reserves for the formation and establishment of new seedlings (Ishibashi et al, 2013;Kim et al, 2011). During the soaking period in this study, there was a mobilization of soluble sugars and decreases in protein content, indicating the use of these components to form new seedlings.…”

-The physiological quality of seeds depends on the cellular organization and their capacity to mobilize reserves. The goal of this study was to assess the germination and vigor of soybeans seeds of Benso1RR and NA 5909 RG cultivars from desiccated plants or not, by mobilizing reserves. Cultivars from desiccated plants or not, by mobilizing reserves. The plants were desiccated with glufosinate ammonium (GLA) in reproductive stage R7.1 or not (TST). The physiological seed quality was assessed by germination tests, accelerated aging and seedling length. For the mobilization of reserves were assessed within 48 hours of soaking: phytate, protein and soluble sugar contents. In 48 hours of soaking, seeds from desiccated plants in cultivar NA 5909 RG showed lower mobilization of soluble protein and soluble sugar, reflecting low vigor seedlings compared to their controls. For cultivar Benso1RR, in 48 hours of soaking, the application of GLA did not affect the mobilization of soluble protein when compared to control and did not differ as to vigor. It is concluded that the use of the desiccant has negatively influenced the mobilization of soluble protein and soluble sugar for cultivar NA 5909 RG, reflecting a low percentage of germination and low vigor.Index terms: vigor, herbicide, protein, soluble sugar.Mobilização de reservas e vigor de sementes de soja sob dessecação com glufosinato de amônio RESUMO -A qualidade fisiológica em sementes depende da organização celular e da sua capacidade de mobilização de reservas. O objetivo do trabalho foi avaliar a germinação e vigor das sementes de soja das cultivares Benso1RR e NA 5909 RG proveniente de plantas dessecadas ou não, através da mobilização de reservas. As plantas foram dessecadas com glufosinato de amônio (GLA) no estádio reprodutivo R7.1 ou não (TST). A qualidade fisiológica das sementes foi avaliada através dos testes de germinação, envelhecimento acelerado e comprimento de plântula. Para a mobilização de reservas foram avaliados em até 48 h de embebição, teores de fitato, proteína e açúcar solúvel. Em 48 h de embebição sementes provenientes de plantas dessecadas da cultivar NA 5909 RG apresentaram menor mobilização de proteína solúvel e açúcar solúvel refletindo em plântulas de baixo vigor em relação a sua testemunha. Para a cultivar Benso1RR em 48 h de embebição, a aplicação do GLA não afetou a mobilização de proteína solúvel quando comparada à testemunha, não diferindo quanto ao vigor. Conclui-se que a utilização do dessecante influenciou negativamente na mobilização de proteína solúvel e açúcar solúvel para a cultivar NA 5909 RG refletindo em baixo percentual de germinação e baixo vigor.Termos para indexação: vigor, herbicida, proteína, açúcar solúvel.

“…This content increased when osmoprimed seedlings were subjected to biosaline water (Table 4). During germination process, synthesis of new proteins relies on provision of adequate amino acids derived from breakdown of storage proteins (Kim et al, 2011). Furthermore, unprimed 2 DAS seedlings germinated under ideal conditions, showed lower AA content in embryonic axis than other treatments, different from what occurred in cotyledons (Table 4).…”

ABSTRACT-Biosaline agriculture has been a viable alternative for agricultural production in regions with lack of good quality water. To enable the cultivation of vegetables in high electrical conductivities, seed priming has been used to increase tolerance to stress caused by use of brackish water. We aimed to evaluate the efficiency of osmo and hydropriming in cucumber seeds cv. Caipira germinated biosaline in water, regarding germination and biochemical changes during the germinative process. The experimental design was totally randomized, with four replications of 50 seeds or 10 seedlings, in a factorial scheme 6x3; with six priming conditions (control, osmopriming during 24 and 48 hours, hydropriming with 1, 2 and 3 cycles of hydration-dehydration) and three biosaline water (fish farming biosaline wastewater) concentrations in distilled water (0, 50 e 100%). We evaluated the kinetics and percentage of germination; germinative metabolism and activity of antioxidant enzymes. According to the results, one hydropriming cycle is faster and more efficient to improve the performance of cucumber seedling in biosaline water and this can be used in substrate for germinating seeds of cucumber cv. Caipira.Index terms: water reuse, Curcubitaceae, seedling development.Modificações fisiológicas em sementes de pepino osmo e hidrocondicionadas germinadas em água biossalina RESUMO -A agricultura biossalina tem sido uma alternativa viável para a produção agrícola em regiões com escassez de água de boa qualidade. Para possibilitar o cultivo de hortaliças em condutividades elétricas elevadas, o condicionamento fisiológico de sementes tem sido utilizado para aumentar a tolerância destas ao estresse causado pela utilização de água salobra. Objetivouse avaliar a eficiência do osmo e hidrocondicionamento em sementes de pepino cv. Caipira em água biossalina, quanto à germinação e as modificações bioquímicas durante o processo germinativo. O delineamento foi inteiramente casualizado, com quatro repetições de 50 sementes ou 10 plântulas, em esquema fatorial 6x3; sendo seis condições de condicionamento fisiológico (controle, osmocondicionamento durante 24 e 48 horas; hidrocondicionamento com 1, 2 e 3 ciclos de hidratação e secagem) e três concentrações de água biossalina (água residuária de piscicultura) em água destilada (0, 50 e 100%). Foram avaliados: porcentagem de germinação; crescimento inicial de plântulas; metabolismo germinativo e atividade de enzimas antioxidantes. De acordo com os resultados obtidos pode-se concluir que um ciclo de hidrocondicionamento é mais rápido e eficiente para melhorar o desempenho das plântulas de pepino em água biossalina, que pode ser utilizada no substrato de germinação de sementes de pepino cv. Caipira.Termos para indexação: reuso de água, Curcubitacea, desenvolvimento de plântulas.

“…Protein mobilization is necessary to meet the demand for amino acids during the early stages of germination and is the first nitrogen mineral nutrient to be used by the seed (Soriano et al, 2011). During the germination process, the development of the embryonic axis and the synthesis of new proteins also depend on the supply of appropriate amino acids derived from the breakdown of storage proteins (Bewley and Black, 1994;Kim et al, 2011).…”

Alterations in seed reserves of Dalbergia nigra ((Vell.) Fr All. ex Benth.) during hydration

et al. 2013

Seed imbibitions is the first stage of the germination process and is characterized by the hydration of tissues and cells and the activation and/or induction of the enzymes responsible for mobilizing reserves for respiration and the construction of new cell structures. The objective of this study was to investigate the alterations in reserve substances during slow hydration of Bahia Rosewood (Dalbergia nigra) seeds in water. Seeds from two different lots (Lot I and II) were placed in saturated desiccators (95-99% RH) to hydrate at 15 and 25 °C until water contents of 10, 15, 20 and 25% were reached. At each level of hydration, changes in lipid reserves, soluble carbohydrates, starch and soluble proteins were evaluated. The mobilization of reserves was similarly assessed in both lots, with no differences being observed between the two hydration temperatures. Lipid contents showed little variation during hydration, while the contents of soluble carbohydrates and starch decreased after the 15% water content level. Soluble proteins showed a gradual tendency to decrease between the control (dry seeds) up to 25% water content.
