Impact of plant and aphid stress history on infestation in arugula plants
(Wiley, 2013-08)
Plants can activate inducible defence mechanisms against pests, pathogens, or chemical elicitors, such as ozone, mediated by reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2). An unfavourable balance ...
Evaluation of late vegetative and reproductive stage soybeans for resistance to soybean aphid (hemiptera: Aphididae)
(2013-04-01)
The soybean aphid, Aphis glycines Matsmura, has become the most significant soybean [Glycine max (L.) Merrill] insect pest in the north central soybean production region of North America. The objectives of this research ...

Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes
(Elsevier, 2019-11)
The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ...
Interacción genotipo x ambiente y análisis de estabilidad en genotipos de amaranto (Amaranthus spp.)
(REVISTA INTERNACIONAL DE BOTÁNICA EXPERIMENTAL INTERNATIONAL JOURNAL OF EXPERIMENTAL BOTANY, 2011)
Five genotypes of amaranth were evaluated: four of
Amaranthus hypochondriacus L. (collect 153-5-3, 653, 655 and Criollo
Tlaxcala) and one of A. cruentus L. genotype 33. Studies were
conducted in the cycle of spring-summer ...
Optimizing row spacing and plant population arrangement for a new short-height castor genotype in fall-winter
(Editora da Universidade Estadual de Maringá - EDUEM, 2014-12-01)
Plant population and arrangement should be properly designed to maximize the seed yield of short-height genotypes of castor (Ricinus communis L.) in each cropping season. Experiments were performed in the in the fall-winter ...
Land equivalent ratio in the intercropping of cucumber with lettuce as a function of cucumber population density
(2020-03-01)
Lettuce and cucumber are two important vegetables cultivated in greenhouses. Intercropping can increase the yield without increasing the demands for inputs. A more efficient use of resources in production systems can reduce ...
Arranjo espacial de plantas de milho em sistema plantio direto
(2008-01-01)
The interaction of management practices that increases plant density and reduces row spacing by spatial arrangement, if well planned, can be an excellent opportunity for the producers to increase their profitability. The ...
