Occurrence and localization of novel antimicrobial and antifeeding compounds in wheat, 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) and 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA), and their glucosides, were examined by staining wheat plants (Triticum aestivum L.) in the juvenile stage of growth by ferric chloride. The methanol extracts of the stained plant tissues gave a characteristic...

Mimicry refers to adaptive similarity between a mimic organism and a model. Mimicry in animals is rather common, whereas documented cases in plants are rare, and the associated benefits are seldom elucidated [1, 2]. We show the occurrence of leaf mimicry in a climbing plant endemic to a temperate rainforest. The woody vine Boquila trifoliolata mimics the leaves of its supporting trees in terms ...

Japanese red pine (Pinus densiflora) is widely present in China, Japan, and Korea. Its green pine leaves have traditionally been used as a food as well as a coloring agent. After being shed, pine leaves change their color from green to brown within two years, and although the brown pine leaves are abundantly available, their value has not been closely assessed. In this study, we investigated th...

Although several types of satellite data provide temporal information of the land use at no cost, digital satellite data applications for agricultural studies are limited compared to applications for forest management. This study assessed the suitability of vegetation indices derived from the TERRA-Moderate Resolution Imaging Spectroradiometer (MODIS) sensor and SPOT-VEGETATION (VGT) sensor for...


 The purpose of this study were to determine the effect leaf maturity on characteristics matcha herbal tea tenggulun and right level which can produce with best characteristics. This used a completely randomized design (CRD) with, namely very young, little old leaves. parameters observed in included moisture content, ash crude fiber tannin total phenol, flavonoids, antioxidant activity, c...

Mature peach leaves are typically about 4 x 16 cm, with a width/length ratio of about 25%. A narrow leaf seedling, selected by Wayne Sherman (Univ. of Florida, Gainesville), was hybridized at USDA-Byron with adapted commercial varieties. Early generation hybrids produced small, irregular-shaped fruit. After 5 generations, current selections are approaching commercial fruit standards in size, co...

In identifying and diagnosing cotton disease the pattern of disease is the important part. Various features of the image can be extracted viz. color of the infected part and by applying various color windows to the disease image and after that we obtained the vector value for this image, also similar procedure is applied for the normal cotton leaf image and that values compared with one another...

This paper proposed a method that combines Polar Fourier Transform, color moments, and vein features to retrieve leaf images based on a leaf image. The method is very useful to help people in recognizing foliage plants. Foliage plants are plants that have various colors and unique patterns in the leaf. Therefore, the colors and its patterns are information that should be counted on in the proce...

Image identification technique is a newly emerge corn disease diagnosis. Disease and background can be isolated base on the image segmentation. The accuracy of the identification result has important impact on corn quality and yield. Plant disease often appears in leaves. In this study, an image extraction algorithm of rice leaf which is based on green component and use the threshold of grey-sc...

Pterospermum acerifolium plant is considered to be laxative, anthelmintic, stomachic and used in inflammation, blood disorders, ulcers and leprosy. The leaf was studied for pharmaconostic evaluations, including examination of morphological and microscopic characters, determination of leaf constants, ash values and extractive values. The morphological studies revealed that the leaf is dark green...
