Um procedimento, baseado no metodo genealogico, foi empregado para verificar o efeito da seleaao em geracoes segregantes de 16 cruzamentos de trigo, para 11 caracteres. O trabalho foi realizado na E.E.A./UFRGS, Guaiba (RS), no bieno 1975/76. As linhas selecionadas, derivadas de plantas F2 e F3, comparadas com os genitores, controles e com as popula...

O dano do percevejo Thyanta perditor (Fabr., 1794)em trigo, foi estudado em condições de campo, submetendo espigas da cultivar BR 12 Aruanã a diferentes populações da espécie. O inseto afetou a quantidade e a qualidade dos grãos, sendo estimado um prejuízo total na produção de 2602kg/ha para uma infestação geral média de cinco percevejos por espiga...

L'étude structurale des protéines par RMN comporte différentes étapes clefs telles que la préparation des macromolécules biologiques, l‘attribution des spectres RMN obtenus ou la reconstruction d'une structure via des étapes de modélisation moléculaire. Une partie de mon travail est relatif à l'étude structurale par RMN de deux thiorédoxines J'ai e...

New plant genotypes were produced using barley-wheat hybrids, Hordeum vulgare L. x Triticum aestivum L., and H. geniculatum All. x T. aestivum L. Biotechnological methods were used. Cytogenetic analysis revealed different characters of formation for fertile alloplasmic lines among progenies of H. vulgare x T. aestivum and H. geniculatum x T. aestiv...

The karyotypes of 47 hybrid lines obtained from crosses of common wheat Triticum aestivum L. (cv. Rodina and line 353) with Triticum timopheevii(Zhuk.) Zhuk. (AtAtGG) and related species T. militinae Zhuk. et Migusch. (AtAtGG) and T. kiharae Dorof. et Migusch. (AtAtGGDsqDsq) were analyzed by C-banding. Most lines were resistant to yellow rust and p...

The cytoplasmic effects on embryo culture responses were studied by using calli from mature embryos of four genotypes of winter wheat (Triticum aestivum L.). Significant reciprocal differences were found for tissue culture response of callus, indicating that a cytoplasmic effect may be involved. In general, cytoplasm positively affected callus indu...
