1. Aumento da Atividade Foliar de Isoproturon+Tribenuron e Pyroxsulam em Erva-Cabecinha e Corriola por Meio de Seleção Adequada de Adjuvantes no Trigo
RESUMO: O uso de adjuvantes para otimizar e aumentar a atividade foliar de herbicidas pós-emergência é uma forma aceitável de reduzir seus efeitos colaterais. Pesquisas de campo foram conduzidas para detectar um adjuvante adequado para dois herbicidas, nomeadamente isoproturon + tribenuron e pyroxsulam, em erva-cabecinha (Phalaris minor) e corriola (Conv

2. O Uso do Sulfato de Alquil Éter na Melhora da Eficácia de Herbicidas Contra a Ançarinha-Branca e a Corriola na Cultura do Trigo
RESUMO: A aplicação de herbicidas em tanque com adjuvante é necessária para o manejo eficaz de plantas daninhas e para a redução da carga de herbicidas em culturas agrícolas. Estudos de campo foram conduzidos para investigar o efeito de herbicidas em doses reduzidas com adjuvante em ansarinha-branca (Chenopodium album) e corriola (Convolvulus arvensis

3. Influência do tamanho da semente e fatores ecológicos na germinação e na emergência de Convolvulus arvensis
O entendimento sobre a ecologia de germinação de sementes de plantas daninhas pode ajudar a prever sua distribuição e a desenvolver estratégias eficazes de manejo. Fatores ambientais e tamanho da semente de Convolvulus arvensis foram estudados em laboratório e em casa de vegetação. A germinação ocorreu através de uma ampla gama de temperatura cons

4. Actividad fitotóxica de un extracto N-Hexano obtenido de la corteza de Drimys Winteri sobre cuatro especies de malezas
The objective of this research was to determine the phytotoxic effect of the n-hexane extract obtained from the bark of Drimys winteri on germination and growth of Convolvulus arvensis, Setaria pumila, Daucus carota and Cichorium intybus. The phytotoxic effects of the extract on the germination of weeds were determined by bioassays in Petri dishes, adding th

5. Efecto de la dosis de glifosato sobre la biomasa de malezas de barbecho al estado vegetativo y reproductivo
Experiments were conducted at the University of Rosario Experimental Farm, Zavalla in 2005 and 2006 to study the effect of glyphosate on the control of Convolvulus arvensis, Oenothera indecora, Iresine diffusa, Parietaria debilis, Rumex paraguayensis and Trifolium repens at the vegetative and reproductive stage. The experiments were established in a complete

9. Isolation and identification of TL-DNA/plant junctions in Convolvulus arvensis transformed by Agrobacterium rhizogenes strain A4
We have constructed a Charon 4A phage library containing insert DNA isolated from a morning glory (Convolvulus arvensis) plant (clone 7) regenerated from a root organ culture incited by Agrobacterium rhizogenes, strain A4. Using a subcloned region of the Ri plasmid as 32P-labeled probe, two lambda clones containing most of the 'left' T-DNA (TL) region were i

10. Deoxyribonucleic Acid Synthesis in Root Cap Cells of Cultured Roots of Convolvulus1
Isolated cultured roots of Convolvulus arvensis L. were incubated in 0.2 microcurie per milliliter methyl-3H-thymidine for 14 hours, for 64 hours, or for 14 hours followed by transfer to fresh nutrient medium without tritiated thymidine. Autoradiographs of serial, longitudinal sections of roots which were continuously incubated with tritiated thymidine showe

11. Cell Wall Regeneration around Protoplasts Isolated from Convolvulus Tissue Culture 1
Protoplasts of Convolvulus arvensis L. tissue culture regenerated a wall-like structure within 3 days in culture. Although unusually electron dense and atypically amorphous in the electron microscope, this structure could be digested with Myrothecium cellulase but was resistant to protease, a Rohm and Haas pectinase, and a β-1, 3-exoglucanase just like the

12. A plasmid of Rhizobium meliloti 41 encodes catabolism of two compounds from root exudate of Calystegium sepium.
Our objectives were to identify substances produced by plant roots that might act as nutritional mediators of specific plant-bacterium relationships and to delineate the bacterial genes responsible for catabolizing these substances. We discovered new compounds, which we call calystegins, that have the characteristics of nutritional mediators. They were detec
