Conteúdo: 	Electrophoretic analysis of storage protein accumulation in developing cowpea (Vigna unguilata (L.) Walp. Mississipi Purple) seed indicated that a large increase in protein content per seed occurred between 10 and 11 days after flowering (DAF). Polypeptides with molecular weights of 54, 49, and 41 kilodaltons (kD) accumulated first, and one with a molecular weight of 59 kD appeared 2 days later at 13 DAF. Treatment of plants with glyphosate (N-(phosphonomethyl)glycine) when pods were 7 and 10 DAF prevented accumulation of these polypeptides was not inhibited as much when pods were 11, 12 or 13 DAF at the time of treatment with glyphosate. Pod lenght and seed fresh weight were inhibited by glyphosate treatment of plants bearing pods 7, 10, 11 and 12 DAF. Podwidth, seed dry weight, and seed lenght were inhibited by glyphosate when plants bearing pods 7, 10, and 11 DAF were treated.
