Variation in canopy structure, leaf area, light interception and light use efficiency among Eucalyptus clones
(2020-05-01)
Differences in growth rates between Eucalyptus clones depend on differences in the acquisition of resources, and the efficiency of using resources to produce carbohydrates and grow wood. We examined differences in canopy ...
Early- And late-waterlogging differentially affect the yield of wheat, barley, oilseed rape and field pea through changes in leaf area index, radiation interception and radiation use efficiency
(Wiley Blackwell Publishing, Inc, 2021-06)
Waterlogging is a severe stress that constrains crop production. We studied ecophysiological traits related to waterlogging tolerance in wheat, barley oilseed rape and field pea. Outdoor experiments using canopies of wheat ...
Ontogenetic variation in light interception, self-shading and biomass distribution of seedlings of the conifer Araucaria araucana (Molina) K. Koch
(Sociedad de Biología de Chile, 2006)
Acclimation to sun and shade of three accessions of the Chilean native berry-crop murta
(2007)
Murta (Ugni molinae Turcz.) is an evergreen shrub of the native forest understorey of southern Chile that produces berries which are consumed in the local markets. Because of the natural adaptation of murta to growing under ...
High tree diversity enhances light interception in tropical forests
(2021-01-01)
Understanding the processes that underlie the effects of tree diversity on primary production is of foremost importance to enhance climate change mitigation by tropical forests. Here, we investigated the effects of tree ...
Genetic improvement of peanut in Argentina between 1948 and 2004: Light interception, biomass production and radiation use efficiency
(Elsevier Science, 2017-03)
An important milestone in Argentina peanut (Arachis hypogaea L.) breeding was the shift in the 1970s from cultivars with erect growth habit (CEGH) to cultivars with procumbent growth habit (CPGH). CPGH improved seed yield ...
Productivity and morphological composition of Xaraes palisade grass under three light intensities
(Univ Estadual Londrina, 2019-11-01)
The adaptation of Urochloa brizantha to Brazilian ecosystems and the use of artificial shading in low light production studies are important tools to obtain productive responses and to know the behavior of plants when used ...
Defoliation affects soybean yield depending on time and level of light interception reduction
(Southern Cross Publishing, 2012-07)
Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ...
Nutritive value and physical characteristics of Xaraes palisadegrass as affected by grazing strategy
(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2010)
The aim of this study was to ascertain whether the defoliation frequency based on a fixed rest period would generate variable sward structural and physiological conditions at each subsequent grazing event. The relative ...
Silage production of corn intercropped with tropical forages in an integrated crop-livestock system with lambs
(2017-01-01)
The objective of this work was to evaluate the effect of intercropping systems between corn and tropical forages, at different cutting heights, on silage production, light interception, land use efficiency, intercropping ...
