Topology of leaves for minimal laminations by non-simply-connected hyperbolic surfaces
(European Mathematical Society, 2022)
We give the topological obstructions to be a leaf in a minimal lamination by hyperbolic surfaces whose generic leaf is homeomorphic to a Cantor tree. Then, we show that all allowed topological types can be simultaneously ...
RadialPheno: A tool for near-surface phenology analysis through radial layouts
(2019-06-01)
Premise: Increasingly, researchers studying plant phenology are exploring novel technologies to remotely observe plant changes over time. The increasing use of phenocams to monitor leaf phenology, based on the analysis of ...
Leaf traits related to productivity in Populus deltoides during the post-flooding period
(Springer, 2015-06)
Key message: After a flooding period,Populus deltoidesplants compensate for the reduced growth under flooding by substituting the leaf area loss instead of increasing the leaf photosynthetic activity. Abstract: Flooding ...
Leaf Surface Scanning Electron Microscopy of 16 Mulberry Genotypes (Morus spp.) with Respect to their Feeding Value in Silkworm (Bombyx mori L.) Rearing
(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Herbivory by leaf-cutter ants changes the glandular trichomes density and the volatile components in an aromatic plant model
(2017-11-01)
Herbivory can induce several structural and functional alterations in the plant secretory system. Glandular trichomes are the main sites of production of volatile organic compounds (VOCs) with several chemical properties ...
Four distinct leaf types in the Brazilian cerrado, based on bundle sheath extension morphology
(2017-01-01)
Plant species have been classified as being either heterobaric or homobaric based on the presence or absence (respectively) of bundle sheath extensions (BSE) in leaf veins. These leaf types differ in their physiological ...
Leaf characters of Lavoisiera, Microlicia and Trembleya (Microlicieae, Melastomataceae) and their implications for taxonomy
(2018-06-01)
In Microlicieae taxonomical delimitation of Lavoisiera, Microlicia and Trembleya is problematic. This study aims to fill this gap by identifying leaf characters that are useful for taxonomy of these genera. Species of ...
Influence of Mycosphaerella and Teratosphaeria leaf diseases on chemical composition of essential oils of Eucalyptus globulus and effect of these essential oils on ascospores germination
(2021-01-01)
In a first step, essential oils were extracted from Eucalyptus globulus leaves, healthy and with symptoms and signs of Mycosphaerella leaf disease (MLD) and Teratosphaeria leaf disease (TLD), in two leaf stages. Stage 1: ...
The reactive surface of Castor leaf [Ricinus communis L.] powder as a green adsorbent for the removal of heavy metals from natural river water
(2013-07-01)
In this study, a green adsorbent was successfully applied to remove toxic metals from aqueous solutions. Dried minced castor leaves were fractionated into 63-μm particles to perform characterization and extraction experiments. ...
