Lipidomic studies of membrane glycerolipids in plant leaves under heat stress.

Progress in lipid research, 2019
Environmental stresses cause membrane damage in terrestrial plants. Studies on the lipids obtained from these plants are required to understand their adaptation to climate change.

Fluorescence emission spectra of plant leaves and plant constituents

Radiation and Environmental Biophysics, 1991
The 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.

Biosorption of pollutants by plant leaves: An empirical review

Journal of Environmental Chemical Engineering, 2019
In recent years, research focus has been shifting towards the development of environmentally friendly systems for the removal of pollutants from effluents. The use of green adsorbents from tree leaves is a key research domain in this regard.

Statistical shape models of plant leaves

2013 IEEE International Conference on Image Processing, 2013
The 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 ...

Purple heart plant leaves extract-mediated silver nanoparticle synthesis: Optimization by Box-Behnken design.

Materials Science and Engineering C: Materials for Biological Applications, 2019
The present research work describes a novel method for green synthesis of silver nanoparticles using purple heart plant leaves extract, which is recognized as frequently found in households as an ornamental plant. The aqueous methanolic extract of purple

Atmospheric Ammonia: Absorption by Plant Leaves

Science, 1972
By 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.

Topology-Regulated Pesticide Retention on Plant Leaves through Concave Janus Carriers

ACS Sustainable Chemistry and Engineering, 2019
Retention, a crucial process in pesticide application, is heavily affected by the extremely low surface energy and micro/nanostructure of plant leaves.

Real-time rendering of plant leaves

ACM SIGGRAPH 2006 Courses on - SIGGRAPH '06, 2005
This 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.

Thermoluminescence of Plant Leaves

1998
Chlorophyll 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 ...

Effects of Gravity on Transpiration of Plant Leaves

Annals of the New York Academy of Sciences, 2009
To clarify effects of gravity on the water vapor exchange between plants and the ambient air, we evaluated the transpiration rate of plant leaves at 0.01, 1.0, and 2.0 g for 20 s each during parabolic airplane flights. The transpiration rates of a strawberry leaf and a replica leaf made of wet cloth were determined using a chamber method with humidity ...
