“…The total soluble sugar and soluble protein contents were estimated as described by Wang et al [2001]. The free amino acid content was determined according to the method of Aragão et al [2015], whereas the content of reducing sugars was measured according to the standard AOAC methods 939.03 [AOAC, 1995].…”

Tartary buckwheat (Fagopyrum tataricum) seeds were irradiated with microwaves at various power levels of 200, 400, 600 and 800 W for 10 or 30 s. The irradiated grains were germinated for 3, 5, and 7 days and harvested. The germination rate of the tartary buckwheat seeds and contents of some compounds in the sprouts were investigated. The results showed that the exposure to 600 W microwaves for 10 s resulted in the highest fi nal germination rate after 7 days of germination, which was 2 times that of the control. The exposure of seeds to 800 W for 30 s showed the lowest germination rate (approximately 10%), which decreased by 87% compared with the control (p<0.05). The exposure at 600 W for 30 s stimulated the total fl avones content, reduced the sugar and soluble protein contents, and increased the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The highest free amino acid content (11 mg/g) was observed in 5-day sprouts exposed to 800 W for 10 s. Moreover, the microwave treatment had a positive effect on the catalase (CAT) and superoxide dismutase (SOD) activity.

“…During germination, proteins stored in seeds are broken down into amino acids, and this hydrolysis releases high levels of ammonium used in the growth of the plantlet (Limami et al 2002). Studies of woody tree species show changes in their amino acid profiles during the processes of seed development (Astarita et al 2003a;Santa-Catarina et al 2006) and germination (Dias et al 2009;Pieruzzi et al 2011;Sasaki et al 2013;Aragão et al 2015), suggesting that amino acids participate in these processes.…”

Due to the economic importance of wood production, species including Cedrela fissilis Vell. and Cariniana legalis (Mart.) Kuntze have been heavily exploited and are currently threatened with extinction. In addition, these species produce seeds with low viability when stored for long periods. In this work, the effect of storage time on seedling emergence and alterations in the levels of biomolecules such as carbohydrates, polyamines (PAs), and amino acids were analyzed in C. fissilis and C. legalis seeds. Seedling emergence and the emergence speed index were significantly reduced during seed storage in both species, with a greater reduction for C. legalis seeds. Sucrose was detected in both species, with the highest levels in C. fissilis seeds, whereas the monosaccharides glucose and fructose were detected only in C. legalis seeds. Higher levels of putrescine (Put) were observed in C. legalis seeds than in C. fissilis seeds. In contrast, C. fissilis seeds showed a significant increase in most of the amino acids analyzed. These results suggest that the presence of glucose and fructose, the higher level of Put, and the lower levels of amino acids observed in C. legalis seeds may be associated with greater reductions in vigor and seedling emergence compared with C. fissilis seeds. This is the first report showing these relationships among carbohydrates, PAs, and amino acids in these species and may be useful for further studies on seed conservation of timber species.

“…The present results are in agreement with these reported by Sibian et al (2017) who found the essential amino acids such as lysine, methionine, leucine, isoleucine, threonine, Isoleucine, phenylalanine and valine and the non-essential ones, which include serine, proline, aspartic acid, alanine and glycine had shown a significant increase during germination; however, the increments in the studied grains were different. Aragao et al (2015) recorded significant differences in the concentrations of each amino acid throughout the days of seed imbibition of Cedrela fissilis . The changes in amino acids pattern might be provided these amino acids by the mobilization of stored proteins in mature seeds.…”

Sprouts are excellent source of, amino acids, enzymes, minerals, phytochemicals and vitamins which are the most useful compounds for the human health. This study aimed to investigate the effect of three germination media (soil mixture consisted of soil + vermiculite + 10 % compost, rice straw and kitchen paper towel) on the production and nutritional value of sprouts artichoke comparing with artichoke heads. The highest sprouts yield was produced on soil mixture. On the other hand, based on dry weight, the comparison among sprouts produced on the different media, indicted that sprouts produced on kitchen paper towel showed the highest values of the most nutritional. Meanwhile, sprouts produced on kitchen paper towel exhibited significantly value higher contents of protein, total lipid, inulin, total sugars, calcium, sodium, phosphorus, antioxidants, the essential amino acids (such as leucine, isoleucine, threonine, phenylalanine and valine) than detected in artichoke heads. Reversely, artichoke heads significantly value higher contents of fibers, carbohydrates, phosphorus, vitamin A, vitamin C, total phenols, chlorogenic acid, cynarin, and the essential amino acid aspartic than all sprouts. The essential fatty acids (linoleic acid, linolenic acid) were determined in sprouts produced on soil mixture and rice straw, but they were not found in artichoke heads and produced on kitchen paper towel. According to the current results, it is recommended to collect artichoke seeds, before they are scattered in the soil at the end of the season, to be used in producing sprouts throughout the year as a source of healthy food and a protection from various serious diseases.
