Leaves of Anogeissus leiocarpus Guill. & Perr. have been traditionally used as an African botanical treatment for parasitic worm infections in both humans and livestock. This current study documents the presence of punicalagin isomers (α & β) and its galloyl ester, 1-O-galloyl-punicalagin as major components in the leaf extract of A. leiocarpus. Identification was performed using HPLC and LC-io...

BACKGROUND The efficacy of systemic applications of imidacloprid for the management of avocado thrips and avocado lace bug was determined in field trials. Following insecticide treatment by chemigation, leaves of appropriate age for each insect were sampled over a 6 month period and used for bioassays. Imidacloprid residues were measured by ELISA in leaves used for bioassays to determine concen...

A new species from Iran is described and illustrated here as Kickxia iranica (Plantaginaceae). Kickxia iranica is morphologically similar to K. commutata, a species native to Mediterranean region, however it can be distinguished from the latter by leaf shape, color of corolla, habit, stem branching and length of leaf, petiole, pedicel and corolla. Notes on its distribution, ecology and phenolog...

We have realized a full color 4-inch quarter-VGA amorphous Silicon AM-LCD on 75 μm flexible glass substrates. The overall thickness of the LC cell is <170 μm. With this work we demonstrate that the incorporated ultra-thin glass substrates have suitable properties to be compatible with a standard color AM-LCD process and achieve active matrix backplanes with reliable

In this review paper we discuss the various methodologies for plant disease detection. Studies show that relying on pure naked-eye observation of experts to detect and classify diseases can be time consuming and expensive, especially in rural areas and developing countries. So we present fast, automatic, cheap and accurate image processing based solution. Solution is composed of four main phase...

Several researches in leaf identification did not include color information as features. The main reason is caused by a fact that they used green colored leaves as samples. However, for foliage plants—plants with colorful leaves, fancy patterns in their leaves, and interesting plants with unique shape—color and also texture could not be neglected. For example, Epipremnum pinnatum ‘Aureum’ and E...

Several methods to identify plants have been proposed by several researchers. Commonly, the methods did not capture color information, because color was not recognized as an important aspect to the identification. In this research, shape and vein, color, and texture features were incorporated to classify a leaf. In this case, a neural network called Probabilistic Neural network (PNN) was used a...

Leaf area index is one of the most important parameters in ecological and environmental studies. This paper presents a method for single leaf area measurement based on the counting of the leaf pixels in digital leaf image. Initially, the target leaf is put on a piece of white paper on which four endpoints of an equal-length and orthogonal cross are printed. A background color threshold is then ...
