Metabolic profiling by ultra-performance liquid chromatography-mass spectrometry and parallel factor analysis for the determination of disease biomarkers in Eucalyptus
(Springer, 2014-12-01)
In this article, we present and discuss an alternative for data analysis of the metabolic profiles of both healthy Eucalyptus globulus and those infected with the Mycosphaerella leaf disease. The crude extracts were analyzed ...
Leaf Spraying of Manganese with Silicon Addition Is Agronomically Viable for Corn and Sorghum Plants
(2020-09-01)
Leaf spraying of manganese (Mn) is widely used in annual crops due to its deficiency in the soil. Silicon (Si) addition in the spray solution with Mn could favor physiological and nutritional aspects and the production of ...
The effect of macroinvertebrate exclusion on leaf breakdown rates in two upland Colombian streams
(Universidad de Costa Rica, 2018)
Nitrogen fertilization and Azospirillum brasilense inoculation on panicum maximum CV. MombasaFertilizacion nitrogenada e inoculación con azospirillum brasilense en la forraje panicum maximum cv. Mombasa
(2020-08-01)
Background. Nitrogen fertilization of pastures is considered one of the main limiting factors and that most promote an increase in the production of forage biomass. For this reason, research that evaluates alternative ...
Long-term effect of carbohydrate reserves on growth and reproduction of Prosopis denudans (Fabaceae): implications for conservation of woody perennials
(Oxford University Press, 2016-01)
Prosopis denudans, an extreme xerophyte shrub, is consumed by ungulates and threatened by firewood gathering, because itis one of the preferred species used by Mapuche indigenous people of Patagonia. In a scenario of ...
Can leaf spectroscopy predict leaf and forest traits along a peruvian tropical forest elevation gradient?
(Agu Publications, 2017-11)
High‐resolution spectroscopy can be used to measure leaf chemical and structural traits. Such leaf traits are often highly correlated to other traits, such as photosynthesis, through the leaf economics spectrum. We measured ...
Oviposition by herbivorous insects induces changes in optical and mechanical properties of Prunus avium leaves
(Springer, 2018-08)
This study of animal–plant interaction focused on the impact of oviposition by an insect on the leaves of Prunus avium (cherries). We examined whether the oviposition by Caliroa cerasi affects leaf mechanical and spectral ...
Accuracy and limitations for spectroscopic prediction of leaf traits in seasonally dry tropical environments
(2020-07-01)
Generalized assessments of the accuracy of spectroscopic estimates of ecologically important leaf traits such as leaf mass per area (LMA) and leaf dry matter content (LDMC) are still lacking for most ecosystems, and ...
Residual leaf area index as strategy to management of pasture: structure of Tanzania grass
(Univ Federal Rural Pernambuco, 2019-01-01)
The study aims to evaluate changes structural in Tanzania grass pasture under intermittent stocking in response to different levels of residual leaf area. The experiment was carried out from the October/2009 May/2011, ...
