Résumé:
In this work, we conducted a physicochemical study of some varieties of
quinoa seeds recently grown in Algeria.
Objectives: This study aims to determine the biochemical and morphological study of seven
varieties of quinoa seeds, newly cultivated in Algeria. This study allowed us to identify the difference
that exists between individuals.
Methods: We touched on conducting several laboratory experiments, namely estimating the
amount of starch and cellulose in two types of quinoa seeds. We also estimated the amount of fatty
substance present in two types of quinoa seeds.
Results and discussion: The results obtained from the biochemical study showed that
individuals Q101, Qgiza02, Qrouge, Qnoir.It is the most special for me the values of the biochemical
analyzes. It is clear to us that the fat content is high in two varieties in quinoa seeds and the percentage
of cellulose is high in the two varieties, as well as a high percentage of starch in the two varieties. The
morphological study showed that individuals are the most distinguished with respect to the majority of
morphological measurements, which recorded the most important values of length, width and weight.
Moreover, revealed to us information that distinguished between the 07 individuals studied through the
values we obtained.
Conclusion: We can deduce from the morphological study that it determines the genetic
diversity of the studied taxa. It also shows us the genetic diversity and the chemical content is very
important for the studied individuals
