This work bears on the study of the morphological characteristics of the widespread weeds seeds in the north east of Algeria （the Setifian high plateau）. Fourteen characteristics were used to identify ninety one species of seeds which belong to nineteen botanical families. The morphological characteristics in which the study was based on are： form, color, size, solidity, brightness, smoothness, seed length, seed width, seed caliber, outgrowths, outgrowths form, outgrowths color, outgrowths length, outgrowths width, weight per 100 seeds. Considerable differences were noticed between the various species of weeds seeds. The study of morphological characteristics of seeds allows identifying the different seeds mixed with cultivated plant, it also allows knowing the various species of weeds in fields. So such studies help to develop different strategies to control weeds.展开更多
