Pollen grain morphology and seed coat characters of 11 cultivars belonging to two species of genus Hibiscus (Family Malvaceae) namely H. esculentus (H. Abelmoschus) and H. sabdariffa were investigated. This study was carried out using light microscope (LM) and Scanning Electron Microscopy (SEM). Pollen morphology of this genus is fairly uniform. Generally radially symmetrical apolar, mostly spheroidal, pantoporate. Seed exomorphic characters revealed four types of ornamentations; reticulate, ocealate, foveolate and ruminate. Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) was employed to characterize those taxa. Thirty one bands of seed protein profiles have been constructed from the gel. The produced dendrograms were analyzed by STATISCA program using UPGMA clustering method showed a close affinity among the seven H. esculentus cultivars and the four H. sabdariffa cultivars.

A collection of 12 varieties of broad bean (Vicia faba L.) was studied. This was curried out to see the variation of phenolic compounds (tannins) and proteins of the seeds of Vicia faba L. This study gave the following results - At the biochemical level; according to our results one observed a high content in proteins within the species of Vicia faba L. - The electrophoresis of total proteins confirmed the richness of proteins of Vicia faba L [albumins (67 kDa), Globulins, Vicilline (50 kDa)]. - Finally the phytochemical analysis (phenolic compounds) allowed us to confirm the richness of the colored seeds in phenolic compounds (condensed tannins) "949 T (183±9.66), Aquadulce (132.19±1.53)". The effect of time (the factor of the environment) inflates on the coloring of the seeds (oxidation) and on the polymerization of tannins.
