SummaryComparisons of reflection, transmittance, and absorptance spectra of heavily glaucous leaves, glaucous leaves from which the glaucescence was experimentally removed, and naturally occurring non-glaucous leaves of a single species (Dudleya brittonii Johansen) reveal that glaucescence, a powdery wax coating on the leaf surface, is responsible for very high reflectance of ultraviolet radiation (UV) and high reflectances of visible and near-infrared radiation. UV reflectance (up to 83% in UV… 

Beneficial Spectral Characteristics of Red and Black Raspberry Plants (Rubus idaeus and Rubus occidentalis)

The variety of spectral strategies employed suggest a sophisticated system of protection from pests, disease, herbivores, ultraviolet radiation, oxygen free radicals, and extreme moisture conditions.

The influence of epidermal windows on the light environment within the leaves of six succulents.

A novel, testable hypothesis is led to that may help to explain previous findings that application of reflective tape to the windows of the leaves of these succulents did not effect a reduction in photosynthetic activity.

Effects of pubescence and waxes on the reflectance of leaves in the ultraviolet and photosynthetic wavebands: a comparison of a range of species

It was found that both pubescence and glaucousness had marked effects on total reflectance, andPubescent leaves tended to be more effective in reflecting longer wavelengths than ultraviolet radiation, and surface waxes were very effective reflectors of both UV and longer wavelength radiation.

Seasonal variation in the reflectance of photosynthetically active radiation from epicuticular waxes of Scots pine (Pinus sylvestris) needles

It is suggested that the observed dynamics in wax reflectance could represent a new photoprotective mechanism operating at the seasonal scale as they modulate the absorption of the photosynthetically active radiation (PAR) over time.

High-resolution spectral information enables phenotyping of leaf epicuticular wax in wheat

Background Epicuticular wax (EW) is the first line of defense in plants for protection against biotic and abiotic factors in the environment. In wheat, EW is associated with resilience to heat and

The Optical Properties of Leaf Structural Elements and Their Contribution to Photosynthetic Performance and Photoprotection

Each particular leaf design incorporates suitable optical traits advantageously and cost-effectively with the other fundamental functions of the leaf, thus offering adaptive advantages in challenging environments.

Ultraviolet screening increases with elevation in translucent bracts of Rheum nobile (Polygonaceae), an alpine ‘glasshouse’ plant from the high Himalayas

The results indicate that the bracts of R. nobile have the ability to cope with enhanced UV radiation with increasing elevation through increased UV absorbance, thus protecting pollen grains from injury caused by higher levels of UV radiation, and consequently ensuring normal sexual reproduction in stressful high-alpine conditions.

Growth of dropwort plants and their accumulation of bioactive compounds after exposure to UV lamp or LED irradiation

High-energy ultraviolet (UV) light is an environmental stress that can be used to stimulate the biosynthesis of bioactive compounds in plants. This study aimed to comparatively determine the effects

Hyperspectral phenotyping of the reaction of grapevine genotypes to Plasmopara viticola.

Hyperspectral characterization at the tissue level proved suitable for phenotyping plant resistance to pathogens and provided information on resistance mechanisms in grapevine breeding.

Cuticular Waxes of Arabidopsis

The chemical composition of cuticular waxes on Arabidopsis leaves and stems are typical of those on many dicotyledonous plants, being composed primarily of saturated free fatty acids, aldehydes, alkanes, primary alcohols, secondarycohols, ketones, and wax esters.



Studies on Leaf Characteristics of a Cline of Eucalyptus urnigera From Mount Wellington, Tasmania. II. Reflection, Transmission and Absorption of Radiation.

Coefficients of reflection of green and glaucous leaves of Eucalyptus urnigera were, respectively, 26 % and 40% for total radiation and 13% and 30% for visible radiation and there was good agreement between the two methods.

Photosynthetic Action Spectra of Trees: II. The Relationship of Cuticle Structure to the Visible and Ultraviolet Spectral Properties of Needles from Four Coniferous Species.

It is concluded that both the bluish appearance (glaucous bloom) and the low relative efficiencies of blue light in photosynthesis of Colorado and Blue spruce result from the selectively enhanced reflection ofblue light caused by the presence of the epicuticular wax deposits.

Studies on Leaf Characteristics of a Cline of Eucalyptus urnigera from Mount Wellington, Tasmania. I Water Repellency and the Freezing of Leaves

It is suggested that the ability of dry leaves to supercool may explain part of the selective advantage possessed by the glaucous water-repellent leaves of E. urnigera at high altitudes as compared with the green wettable leaves of plants at low altitudes.


The type of this very distinct species was collected by H. Callens (No. 2275) at Panzi, Belgian Congo, on February 8, 1950, and is deposited in the Britton Herbarium at the New York Botanical Garden.

Leaf epidermal transmittance of ultraviolet radiation and its implications for plant sensitivity to ulraviolet-radiation induced injury

SummaryLeaf epidermal transmittance of ultraviolet radiation (280–400 nm) was examined in several plant species to determine the capability of the epidermis to attenuate solar ultraviolet radiation.

Leaf Pubescence: Effects on Absorptance and Photosynthesis in a Desert Shrub

The presence of leaf pubescence (leaf hairs) in E. farinosa, a desert species of the Composite family, reduces the absorptance of photosynthetically active radiation by as much as 56 percent more than a closely related but nonpubescent species, E. californica.

Ultraviolet Radiation Reflectance, Transmittance, and Absorptance by Plant Leaf Epidermises1

It is concluded that leaves of plants with thick epidermises would have less internal damage to inner tissues of their mesophylls by UV-B radiation than leaves with thinner epidersmises; however, UV- B radiation may damage the epidermis itself.

Optical properties of leaves of some species in arid South Australia.

Of the species in the group, Atriplex vesicaria had the highest coefficient of reflection, and also the lowest coefficient of absorption, and the group as a whole could not be clearly separated from the comparison group on the basis of reflection or absorption coeficients.

Spectral Properties of Plants

The spectral properties of plant leaves and stems have been obtained for ultraviolet, visible, and infrared frequencies. The spectral reflectance, transmittance, and absorptance for certain plants is

A negative correlation was obtained between susceptibility of leaves to P. eucalypti leaf spot and the weight per unit leaf area of ether-soluble substances also soluble in water.
