“…There have been many studies describing the chemical composition of quinoa seeds but direct comparison of results is difficult. It has been proved that, due to the huge genetic variability, quinoa can be adapted effectively and easily to a wide range of environmental conditions . So far, quinoa has been tested in diverse climatic regions, e.g.…”

“…Undoubtedly, both agro and climatic factors strongly influence its chemical composition, e.g. cultivation at high altitudes usually increases the content of anti‐nutritional factors (phenolics, hydrolase, inhibitors) and decreases the accumulation of nutrients in seeds . On the other hand, cultivation of the same cultivars with different agronomic treatments is also responsible for significant differences in the yield and nutrient content, e.g.…”

Background Quinoa seeds are an excellent source of nutrients and phytochemical compounds with well documented activity; however, different cultivars are usually characterized by different physical properties and chemical composition. This study presented the physical properties, nutrient content, and antioxidant capacities of 25 cultivars of yellow‐coated quinoa. Results The results demonstrated that quinoa seeds may be an excellent source of dietary fiber (up to 198 g kg−1 d.m. – Baer cultivar), with a 1:2 ratio of the soluble to insoluble fraction. Digestible carbohydrates were present at the highest level in the Puno cultivar (640 g kg−1). The highest content of proteins was determined in the Colorado 407D and Faro cultivars (c.a. 16%). The average content of albumin and globulins in the seeds was 29.2 and 65.6 g kg−1, respectively. The quinoa seeds were characterized by low activity of protease inhibitors. The lowest inhibition of trypsin was determined for the UDEC‐3, Faro Orange, and Titicaca cultivars, and the highest value was exhibited by the Titicaca White and UDEC‐5 cultivars. Phenolics in the tested cultivars ranged from 7.1 g kg−1 (UDEC‐3) to 10.6 g kg−1 (Temuko). The best antiradical properties were determined for Temuco and Rainbow (2.05 g TE kg−1 and 1.85 g TE kg−1, respectively), while the Baer and Temuco cultivars were characterized by the highest reducing power (2.28 g TE kg−1 and 2.17 g TE kg−1, respectively). Conclusion This study has shown that quinoa cultivated in European countries is a good source of nutrients, dietary fiber, and antioxidants; however, its composition varies significantly. © 2019 Society of Chemical Industry

Quinoa (Amaranthaceae) is a native pseudo-cereal produced throughout the South American zone, where it is used in the preparation of food and as a promising alternative for the colonization of edaphoclimatic areas affected by anthropic and natural factors. Among the main problems that affect crop production, we can include those related to growth, development and production, generated by limitations of adaptability of new cultivars in specific areas. For this reason, this research intended to analyze the growth and morphphysiological behavior of the cultivars of quinoa Blanca Soracá (BS), Blanca Jericó (BT), and Tunkahuan (T). The study was carried out in the greenhouse of the Faculty of Agricultural Sciences of the Cauca University (Colombia) located at 1880 m a.s.l. The analysis, allowed to recognize that the three cultivars of quinoa, show different times of phenological development, until harvest (138.25 ± 2.3 and 161 ± 1.1 days). The number of leaves, the height of plants, and the number of branches show adjustment of sigmoidal regression equations (R 2 0.99 -0.98) for the cultivars BJ and T, while total chlorophyll content was adjusted to cubic behavior (R 2 0.90 -0.89). The cultivars of quinoa express productive behaviors that are associated with early and late cycles, showing differences in the production and weight of seeds. RESUMOQuinoa (Amaranthaceae) é um pseudo-cereal nativo produzido em toda a zona sul-americana, onde é utilizada como alimento e alternativa promissora para o cultivo em áreas edafoclimáticas afetadas por fatores antrópicos e naturais. Entre os principais problemas que afetam a produção agrícola, inclui-se aqueles relacionados ao crescimento, desenvolvimento e produção, gerados por limitações de adaptabilidade de novas cultivares em áreas específicas. Por este motivo, esta pesquisa teve como objetivo analisar o crescimento e o comportamento morfológico das cultivares de quinoa Blanca Soracá (BS), Blanca Jericó (BT) e Tunkahuan (T). O estudo foi realizado na estufa da Faculdade de Ciências Agrárias da Universidade de Cauca (Colômbia) a 1880 m.a.n.m A análise permitiu reconhecer que as três cultivares de quinoa apresentam diferentes épocas de desenvolvimento fenológico até a colheita (138,25 ± 2,3 e 161 ± 1,1 dias). O número de folhas, a altura das plantas e o número de ramos mostram ajuste às equações de regressão sigmoidal (R 2 0,99 -0,98) para as cultivares BJ e T, enquanto o teor de clorofila total foi ajustado para comportamento cúbica (R 2 0,90 -0,89). As cultivares de quinoa expressam comportamentos produtivos associados a ciclos precoces e tardios, mostrando diferenças na produção e peso das sementes.

“…The observed reduction of leaf area under salinity treatments compared to control plants also suggests that salinity stress may affect plant growth through reduction in leaf area. Previous works have disclosed that salt tolerant plants displays less growth retardation and have relatively higher growth rate compared to sensitive ones under salinity stress (Carillo et al, 2019; Hussain et al, 2018; Sarabi et al, 2017;). Consequently, our findings suggest that GBK043128 and GBK043137 have a better capacity to sustain growth and development under salt treatments compared to other finger millet varieties studied, to sustain growth and production under salinity conditions (Table 2).…”

Finger millet is one of the most important cereals that are often grown in semiarid and arid regions of East-Africa. Salinity is known to be a major impediment for the crop growth and production. This study was aimed to understand the mechanisms of physiological and biochemical responses to salinity stress of Kenyan finger millet varieties (GBK043137, GBK043128, GBK043124, GBK043122, GBK043094, GBK043050) grown across different agroecological zones under NaCl-induced salinity stress. Seeds were germinated on the sterile soil and treated using various concentrations of NaCl (100, 200 and 300 mM) for two weeks. Again, the early-seedling stage of germinated plants was irrigated with the same salt concentrations for 60 days. Results indicated depression in germination percentage, shoot and root growth rate, leaf relative water content, chlorophyll content contents, leaf K+ concentration, and leaf K+/Na+ ratios increased salt levels. Contrary, proline and malonaldehyde (MDA) contents reduced sugar content and leaf total proteins. At the same time, the leaf Na+ and Cl− amounts of all plants increased substantially with rising stress levels. Clustering analysis revealed that GBK043094 and GBK043137 were placed together and identified as salt-tolerant varieties based on their performance under salt stress. Overall, our findings indicated a significant varietal variability for most of the parameters analysed. These superior varieties identified could be potentially used as promising genetic resources in future breeding programmes development directed towards salt-tolerant finger millet hybrids. Further analysis at genomic level need to be undertaken to better understand the genetic factors that promote salinity tolerance in finger millet.
