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.

Plant biology: How the humble plant droops its leaves
Current Biology, 2023The humble plant (Mimosa pudica) droops its leaves in response to touch. A new study explains how changes of turgor pressure exerted by protoplasts on surrounding cell walls translate into directional cell deformation that drives leaf movement.

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.

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.

Photopyroelectric Microscopy of Plant Leaves
International Journal of Thermophysics, 2007The use of photothermal microscopy to obtain superficial and in-depth images, by means of the interaction of a thermal wave with the analyzed material, has reached great interest due to its numerous applications. The application of the photopyroelectric microscopy technique to obtain images of plant leaves is presented in this article.

Harnessing biological nitrogen fixation in plant leaves
Trends in Plant Science, 2023The importance of biological nitrogen fixation (BNF) in securing food production for the growing world population with minimal environmental cost has been increasingly acknowledged. Leaf surfaces are one of the biggest microbial habitats on Earth, harboring diverse free-living N2-fixers.

Aerosol deposition on plant leaves
Water, Air, and Soil Pollution, 1977An aerosol generator and wind tunnel system designed for use in aerosol deposition are described. Gross deposition on rough pubescent leaves was nearly seven times greater than on smooth, waxy leaves. Results suggest that aerosol deposition, on a per unit area basis, for single horizontal streamlining leaves is similar to that for arrays of leaves ...

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 ...

Annals of Botany, 1979
Tomato plants were grown with limited or luxury water supply and given nitrogen either as the ammonium ion or the nitrate ion. The 'active' iron fractions of the leaves as extracted by etherized tenth molar hydrochloric acid showed no relationship with the total iron but a very significant linear relationship was found between the active iron fraction ...
