Vegetative and reproductive plasticity of broccoli at three levels of incident photosynthetically active radiation
(2007)To study the effects of shading on the growth, development, dry matter partitioning, and plant architecture of broccoli, "Legacy" hybrid plants were grown in pots in a greenhouse under black shading meshes to generate ... -
Velocidad de avance de la cosechadora y su relación con el funcionamiento del cabezal maicero
(Ediciones INTA, 2019-04)En el presente trabajo fue evaluada la influencia de diferentes relaciones entre la velocidad lineal de los rolos espigadores de un cabezal maicero y la velocidad de avance de la cosechadora en las pérdidas de cosecha en ... -
Verificación de una metodología analítica para cuantificación de fósforo total por espectrofotometría
(EEA Pergamino, INTA, 2022-12)Puesta a punto de una metodología analítica compendiada para la cuantificación de fósforo total por espectrofotometría,en muestras de alimento y excreta de aves. Se realizó la comparación de los resultados obtenidos en el ... -
Vigor inicial de variedades de trigo y su relación con la capacidad supresiva de malezas
(Ediciones INTA, 2018-04)El uso de la capacidad supresiva de diferentes variedades de trigo es una alternativa para el manejo de malezas debido a la capacidad para interferir en el crecimiento de las mismas. La materia seca de las láminas foliares ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
(2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ... -
Volatile metabolite profiling reveals the changes in the volatile compounds of new spontaneously generated loquat cultivars
(2017-10)In recent years, the advantageous traits of three new loquat cultivars have drawn the attention of breeders and growers. All three have spontaneously arisen from the ‘Algerie’ cultivar: the new ‘Xirlero’ cultivar is a bud ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
(Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
(Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
What to Expect as Corn Yields Face a Third Straight La Niña
(University of Illinois, 2022-07-11)Meteorologists are forecasting a third consecutive year of La Niña. The occurrence of two successive La Niña winters in the Northern Hemisphere is common, however, having three in a row is relatively rare. A triple La Niña ... -
Wheat Outlook After Five Months of War in Ukraine
(University of Illinois, 2022-08-01)Even with the projection of increased wheat production in some countries, the world harvest is expected to be a little smaller as a result of effects of the war in Ukraine. Global production for the marketing year 2022/2023 ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
(Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
(2018-01)Fine tuning wheat phenology is of paramount importance for adaptation. A better understanding of how genetic constitution modulates the developmental responses during pre-anthesis phases would help to maintain or even ... -
Wheat yield progress and stability during the last five decades in Argentina
(Elsevier, 2021-07)Improvement of grain yield (GY) at farm level, which is closely related to GY potential, seems to be the main alternative to increase wheat (Triticum aestivum L) production. The aim of current research was to assess the ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ... -
