Genetic variability for leaf growth rate and duration under water deficit in sunflower: analysis of responses at cell, organ, and plant level
(Oxford Academic Press, 2008-05)
Plants under water deficit reduce leaf growth, thereby reducing transpiration rate at the expense of reduced photosynthesis. The objective of this work was to analyse the response of leaf growth to water deficit in several ...
Automatic Leaf Epidermis Assessment Using Fourier Descriptors in Texture Images
(Bio-protocol, 2017-12-05)
The identification of plant species is not a trivial task, since it is carried out by experts and depends on the presence of fruits, flowers and leaves. However, fruits and flowers are not available throughout the year, ...
Leaf venation of living species of Persea (Lauraceae), with taxonomic and nomenclatural notes
(Magnolia Press, 2022-03-15)
With the aim of recognizing and identifying both fertile and sterile specimens of Persea, leaf venation patterns of 54 taxa were studied, 36 of them being described and illustrated for the first time. Analysis of a matrix ...
Manipulação experimental da colonização de detritos foliares por invertebrados aquáticos em um riacho tropical de 3ª ordem
(2015-01-01)
Through a manipulative experiment, the colonization of leaf litter by invertebrates was investigated in two sections of a tropical stream (spatial scale) that differed in function of the canopy cover, one with the presence ...
Measuring and analyzing color and texture information in anatomical leaf cross sections: An approach using computer vision to aid plant species identification
(2011-07-01)
Currently, studies on leaf anatomy have provided an important source of characters helping taxonomic, systematic, and phylogenetic studies. These studies strongly rely on measurements of characters (such as tissue thickness) ...

Using phenological cameras to track the green up in a cerrado savanna and its on-the-ground validation
(Elsevier B.V., 2014-01-01)
Plant phenology has gained new importance in the context of global change research, stimulating the development of novel technologies for phenological observations. Regular digital cameras have been effectively used as ...
