Leaf Physiology of Shade-Grown Cycas micronesica Leaves Following Removal of Shade
The Botanical Review, 2004I. Abstract The photosynthetic characteristics of Cycas micronesica K.D. Hill were studied from August 1998 until February 1999 using chlorophyll fluorescence and gas-exchange techniques to determine the responses to long-term shade of 35% ambient light transmission, followed by the transfer of shade-grown leaves into full-sun conditions.

Sun and shade leaves in two Jurassic species of Pteridosperms
Review of Palaeobotany and Palynology, 1998Abstract Two types of leaves were observed in Komlopteris nordenskioeldii (Nathorst) Barbacka and Ctenozamites cycadea (Berger) Schenk. The differences relate both to morphological and cuticular features and correspond with characters of sun and shade leaves in Angiosperms. This feature is discussed for the first time in Pteridosperms.

Exposed red (anthocyanic) leaves of Quercus coccifera display shade characteristics
Functional Plant Biology, 2003Young leaves in some plants are transiently red due to the presence of anthocyanins, which disappear upon maturation. We investigated the hypothesis that light attenuation by anthocyanins may lead to a shade acclimation of the photosynthetic machinery in red leaves.

Review of Palaeobotany and Palynology, 2001
An ultrastructural transmission electron microscope (TEM) study of fossil leaf cuticles from the Jurassic pteridosperm Komlopteris nordenskioeldii (Nathorst) Barbacka from the Mecsek Mountains (South Hungary) was conducted. Remnants of cuticles of leaves originating from so-called "sun and shade" environments were sectioned with a diamond knife ...

Effects of canopy shade on the lipid composition of soybean leaves
Physiologia Plantarum, 1997The effect of canopy shade on leaf lipid composition was examined in soybeans (Glycine max cv. Young) grown under field conditions. Expanding leaves were tagged at 50, 58 and 65 days after planting (DAP) in plots with either a high (10 plants m−1 row) or low (1 plant m−1 row) plant density.

Leaf Angle: An Adaptive Feature of Sun and Shade Leaves
Botanical Gazette, 1979Ten woody deciduous dicot species, ranging from obligate sun plants to facultative sun/shade plants, were grown in full sun and approximately 17% of full sun. Observations of leaf orientation showed that the leaves of most species are slanted, some to nearly vertical, in full sun and are more nearly horizontal in the shade.

Graphene is fundamentally a two-dimensional material with extraordinary optical, thermal, mechanical, and electrical characteristics. It has a versatile surface chemistry and large surface area. It is a carbon nanomaterial, which comprises sp2 hybridized carbon atoms placed in a hexagonal lattice with one-atom thickness, giving it a two-dimensional ...

A Theoretical Analysis of CO2 Absorption in Sun Versus Shade Leaves
Journal of Biomechanical Engineering, 1978A one-dimensional, steady-state, constant temperature model of diffusion and absorption of CO2 in the intercellular air spaces of a leaf is presented. The model includes two geometrically distinct regions of the leaf interior, corresponding to palisade and spongy mesophyll tissue, respectively.
