Close-spaced plant arrangement optimizes castor biomass and seed yields in tropical fall–winter conditions
(2022-01-01)
The high seed yield and optimum harvesting of short-height castor (Ricinus communis L.) genotypes have enabled its large-scale cultivation and introduction in the Brazilian cropping systems. Thus, studies to optimize plant ...
On-plant larval movement and feeding behavior of fall armyworm (Lepidoptera: Noctuidae) on reproductive corn stages
(Oxford University Press, 2015-10-17)
Spodoptera frugiperda J.E. Smith (fall armyworm) is considered one of the most destructive pests of corn throughout the Americas. Although this pest has been extensively studied, little is known about its larval movement ...
Cytokinins: A key player in determining differences in patterns of canopy senescence in Stay-Green and Fast Dry-Down sunflower (Helianthus annuus L.) hybrids
(Elsevier Science, 2017-05)
Leaf senescence during grain filling can reduce crop yield. We studied, under field conditions and during grain-filling, the association between leaf cytokinin levels and the onset of leaf senescence in sunflower hybrids ...
Effect of canopy openness on growth, specific leaf area, and survival of tree seedlings in a temperate rainforest of Chiloé Island, Chile
(Taylor & Francis, 2005)
Tree species of intermediate-shade tolerance may regenerate in canopy gaps as well as in the forest understory. However, seedling performance may vary widely between shaded and open habitats. In this study, we assessed the ...
Relação entre o fluxo luminoso interceptado em diferentes épocas no índice de área foliar de diferentes forrageiras
(Universidade Estadual de Londrina (UEL), 2011-01-01)
The objective was to evaluate the leaf area index of six different grasses. The experiment was installed at the Instituto Federal de Tecnologia e Educacao of Uberaba, using a randomized block design with split plots in ...
Water-use efficiency declines during autumn leaf senescence in three deciduous tree species, North Carolina piedmont, USA.
During fall leaf senescence in deciduous species, photosynthesis nears completion due to chlorophyll breakdown and re-assimilation. However, several other processes such as leaf nutrient uptake, re-translocation, and ...

Crescimento, desenvolvimento e produtividade de clones avançados de batata em cultivo de primavera e de outono em ambiente subtropical
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2011-12-16)
The objectives of this dissertation were to determine the phyllochron, the final leaf
number on the main stem and the duration of developmental stages to characterize leaf growth
during the developmental cycle and to ...
Soybean leaf age and plant stage influence expression of resistance to velvetbean caterpillar and fall armyworm
(2021-01-01)
Numerous species of herbivorous insects are associated with soybeans, including the specialist velvetbean caterpillar (VBC), Anticarsia gemmatalis, and the generalist fall armyworm (FAW), Spodoptera frugiperda. Expression ...
