Abstract
The present work is devoted to investigate the chemical composition of some
seeds oi three different species, each include two varieties or cultivars. representing
three genera and three families .
The aim of the present work was to clearity the importance and the significance
of the seed chemical composition as critera in taxonomic aspects. The general
chemical analysis including lipid content, protein contents, total carbohydrates.
mineral constituents. amino and fatty acids were determined in seed plant sample of
the studied cultivars and varieties to facilitate the separation of the studied taxa, as
well as. their use as criteria in taxonomic treatments.
The results obtained can be summarized as follows:-
t-The percentage of the chemical contents in seeds variel according to cultivars and
varieties under study.
2-High values of lipid crude protein and mineral element (i e., K, P, Mg, Fe and Cu)
contents in seeds were recorded. While lower values of carbohydrate contents in
seeds of cotton (cv. Giza 86), tomato ( var, Grandifolium) and rape (var. Tower)
wererecorded ascompared with the other cultivars and varieties under study.
3-Different percentages of some amino acids were noticed between seed cotton
cultivars and tomato varieties, high values of Glutamic acid, Asparatic, Arginine,
Proline, Leucine, Phenylalanine and Valine were recorded in these seeds. While,
the centent of their amino acids were nearly the some in both rape seed cultivars.
4- Different percentages of saturated and unsaturated fatty acids were detected
between the studied cultivars. Higher values of Palmitic acid and Linoleic acid were
recorded in oil seeds of cotton (cv. Giza 66), tomato (var. Grandfolium) and rape
(var. Tower) as compared with the other Cultivars.
5*High values of Erucic acid in oil rapetvar. Tower) and tomato (var. Pynforme) and
also, Linolenic acid in oil rape(var. Pactol) were recorded. On the other hand
Palmitoleic acid was not dected in oil seed of cotton (cv. Giza 66}
it is quite clear that. different chemical compositions and their ambunts could
be considered as diagnostic features that make differentiation between the studied
cuitivars and varieties easier and more effective.
