Bolting and flowering are key processes during the growth and development of Chinese cabbage (Brassica rapa L. ssp pekinensis). Understanding the molecular mechanisms underlying bolting and flowering is of significance for improving production of the vegetable. A leaf-color change from bright green to gray-green has been observed following differentiation of the flowering stem and before boltin...

In this research, identification and classification of cotton diseases is done. The pattern of disease is important part where some features like the colour of actual infected image are extracted from image. There are so many diseases occurred on cotton leaf so the leaf color is different for different diseases. This paper uses k-mean clustering with Discrete Wavelet Transform for efficient pla...

T h e PROSPECT leaf optical properties and SAIL canopy reflectance models were coupled and inverted using a set of 96 AVIRIS (Airborne Visible~Infrared Imaging Spectrometer) equivalent spectra gathered in afield experiment on sugar beet plots expressing a large range in leaf area index, chlorophyll concentration, and soil color. In a first attempt, the model accurately reproduced the spectral r...

Objective: The purpose of this study was to evaluate the effects of application of three over the counter whitening toothpastes (Colgate Optic White, Aquafresh Ultimate White and Crest 3D White) on the color stability of different esthetic restorative materials (Resin composite/Filtek Z250 XT, resin modified glass ionomer/GC Fuji II LC, and glass ionomer/Ketac Molar Quick Aplicapweek) commonly ...

A digital image analysis method previously used to evaluate leaf color changes due to nutritional changes was modified to measure the severity of several foliar fungal diseases. Images captured with a flatbed scanner or digital camera were analyzed with a freely available software package, Scion Image, to measure changes in leaf color caused by fungal sporulation or tissue damage. High correlat...

To identify the larvicidal activities of silver nanoparticles synthesized with Acanthus ilicifolius (A. ilicifolius) leaf extract against the larvae of Armigeressubalbatus and Aedesaegypti. In vitro larvicidal activities such as LC50 and LC90 were assessed for the A. subalbatus  and Ae.aegypti larval species. F...

Phloem exudate collected from hybrid poplar (Populus trichocarpa x Populus deltoides) was estimated to have more than 100 proteins, of which 48 were identified using LC-MS/MS. Comparative two-dimensional gel electrophoresis demonstrated that two phloem exudate proteins were significantly (P<0.05) upregulated 24 h after leaf wounding. These were identified as pop3/SP1 and a thaumatin-like protei...

OBJECTIVE To investigate the antioxidant activities as well as phytochemical constituents of Antidesma thwaitesianum Müll. Arg. leaf extracts. METHODS The leaves of A. thwaitesianum were extracted using three different methods: blending with distilled water, maceration with ethanol and decoction. The chemical antioxidant activity of the plant leaf extracts was evaluated using 2,2-diphenyl-1-p...
