Rendering plant leaves faithfully
ACM SIGGRAPH 2003 Sketches & Applications, 2003The light passes through these cells into the spongy layer of the leaf. The elliptical cells, which are interspersed with intercellular air spaces, cause internal scattering of the incident radiation and thereby distribute the light within the leaf. This process is important for an optimal absorption of the light by the leaf’s mesophyll.

From plant physiology to pharmacology: fusicoccin leaves the leaves
Planta, 2018This review highlights 50 years of research on the fungal diterpene fusicoccin, during which the molecule went from a tool in plant physiology research to a pharmacological agent in treating animal diseases. Fusicoccin is a phytotoxic glycosylated diterpene produced by the fungus Phomopsis amygdali, a pathogen of almond and peach plants.

Estimation of plant species by classifying plants and leaves in combination
Journal of Field Robotics, 2017AbstractInformation on which weed species are present within agricultural fields is a prerequisite when using robots for site‐specific weed management. This study proposes a method of improving robustness in shape‐based classifying of seedlings toward natural shape variations within each plant species.

Fluorescence emission spectra of plant leaves and plant constituents
Radiation and Environmental Biophysics, 1991The UV-B radiation (e.g. 337 nm) induced blue fluorescence (BF) and red chlorophyll fluorescence spectra (RF) of green leaves from plants with different leaf structure were determined and the possible nature and candidates of the blue fluorescence emission investigated.

Statistical shape models of plant leaves
2013 IEEE International Conference on Image Processing, 2013The shapes of plant leaves are of great importance to plant biologists and botanists, as they can help in distinguishing plant species, measuring their health, analyzing their growth patterns, and understanding relations between various species. We propose a statistical model that uses the Squared Root Velocity Function representation and a Riemannian ...

Atmospheric Ammonia: Absorption by Plant Leaves
Science, 1972By monitoring the disappearance of ammonia from an airstream flowing through a small growth chamber containing a single plant seedling, it was discovered that plant leaves absorb significant quantities of ammonia from the air, even at naturally occurring low atmospheric concentrations.

Real-time rendering of plant leaves
ACM SIGGRAPH 2006 Courses on - SIGGRAPH '06, 2005This paper presents a framework for the real-time rendering of plant leaves with global illumination effects. Realistic rendering of leaves requires a sophisticated appearance model and accurate lighting computation. For leaf appearance we introduce a parametric model that describes leaves in terms of spatially-variant BRDFs and BTDFs.

Biophotonic in situ sensor for plant leaves
Applied Optics, 2010Knowledge of the water concentration of plants can be helpful in several environmental and agricultural domains. There are many methods for the determination of water content in plant leaves; however, most of them give a relative moisture level or an analytical measure after a previous calibration procedure. Even for other biochemical compounds such as

Thermoluminescence of Plant Leaves
1998Chlorophyll luminescence (delayed fluorescence) originates from photosystem-II (PS-II) and results from the recombination of charges pairs created by a previous illumination. Thermoluminescence (TL) is a particular technique to study luminescence emission, which consists in (i) cooling the sample before or immediately after an illumination at a ...
