in this study, extracts and essential oils of black and red pepper and thyme were tested for antibacterial activity against escherichia coli o157:h7 andstaphylococcus aureus. black and red pepper and thyme were provided from iranian agricultural researches center. 2 g of each plant powder was added to 10 cc ethanol 96°. after 24 h, the crude extract was separated as an alcoholic extract and con...

Pepper pericarp microbiota plays an important role in the pepper peeling process for the production of white pepper. We collected pepper samples at different peeling time points from Hainan Province, China, and used a metagenomic approach to identify changes in the pericarp microbiota based on functional gene analysis. UniFrac distance-based principal coordinates analysis revealed significant c...

Since chili pepper plant size directly reflects the state of plant growth, a method for pepper measurement of plants size was discussed here. Pepper plants were shot from above once per week in the greenhouse since being field planted in spring. The method of processing the pepper plant images was studied, in which the image segmentation of combination of color space and the image morphological...

Potyviruses are one of the most destructive viral pathogens of Solanaceae plants. In Capsicum annuum landrace CM334, a broad-spectrum gene, Pvr4 is known to be involved in resistance against multiple potyviruses, including Pepper mottle virus (PepMoV), Pepper severe mosaic virus (PepSMV), and Potato virus Y (PVY). However, a potyvirus avirulence factor against Pvr4 has not been identified. To i...

B lack pepper from the Piper nigrum L. vine (Figure 1) is the most commonly used spice worldwide, and its extracts have been used as a folk medicine in a variety of cultures. Piper nigrum is used for the production of both black pepper (from the unripened fruit) and white pepper (from the dehulled mature berry). In ancient Sanskrit literature, black pepper use for medicinal purposes was documen...

Aphis gossypii Glover is one of the most important pests of greenhouse cucumber and pepper in the world and Iran. In this research, life table and biology of A. gossypii were investigated on cucumber (Cucumis sativus cv. Super Sultan) and pepper (Capsicum annum cv. Marqueza) in a growth chamber at 25±1°C and 60±5% RH and a photoperiod of 14 L: 10 D hour. The results showed that developmental ti...

Four pepper genotypes classified as resistant and four pepper genotypes classified as susceptible to several avirulent populations of M. incognita were compared for their reactions against a population of Meloidogyne incognita (Chitwood) Kofoid and White which had been shown to be virulent to resistant bell pepper (Capsicum annuum) in preliminary tests. The virulent population of M. incognita o...

This study aimed to investigate the in vitro bioaccessibility of vitamin C from various fruits and vegetables. Vitamin 14 8 vegetables was examined under simulated gastrointestinal digestion method. values were analyzed by reverse-phase High-Performance Liquid Chromatography. The initial amounts ranged between 1.9 (yellow apple) 61.8 mg/100 g (strawberry) 3.8 (curly lettuce) 326.9 (purple cabba...

Dietary red pepper suppresses energy intake and modifies macronutrient intake. We have investigated whether a stimulus in the mouth and the sensation of spiciness are necessary for red pepper-induced changes in energy and macronutrient intake in human volunteers. In a preliminary test, sixteen Japanese male volunteers tasted samples of a soup with graded doses of red pepper in order to define a...

Biological efficacy of rapeseed spray oil against twospotted spider mite (Tetranychus urticae Koch) on cucumber, against European red mite [Panonychus ulmi (Koch)] on apple, green peach aphid (Myzus persicae Sulzer) on pepper and pear psylla [Cacopsylla pyri (L.)] was evaluated in seven field and three greenhouse trials at eight localities in Serbia during 2005-2008. The efficacy of rapeseed sp...
