Root-knot nematodes of the genus Meloidogyne are important pathogens affecting vegetable crop production in Brazil and worldwide. The pepper species Capsicum annuum includes both hot and sweet peppers; very little emphasis has been placed on breeding sweet peppers for nematode resistance. We report on the inheritance of resistance to Meloidogyne incognita (Kofoid & White) Chitwood race 2 in the...

Capsicum species produce fruits that synthesize and accumulate carotenoid pigments, which are responsible for the fruits' yellow, orange and red colors. Chili peppers have been used as an experimental model for studying the biochemical and molecular aspects of carotenoid biosynthesis. Most reports refer to the characterization of carotenoids and content determination in chili pepper fruits from...

BACKGROUND Capsaicin, the pungent extract of red peppers, has achieved widespread use in clinical research because it induces cough in a dose-dependent and reproducible manner. Although > 2 decades of experience has led investigators to consider capsaicin cough challenge testing a safe diagnostic modality, this issue has not been specifically addressed in the literature. STUDY OBJECTIVES To r...

Capsaicin is the major pungent ingredient in red peppers which is world widely consumed. Except its potent pain relieving efficacy as reported, capsaicin also exerted its antitumor activity in several tumor models. Here, we reported that capsaicin had a profound anti-proliferative effect on human colon cancer cells via inducing cell cycle G0/G1 phase arrest and apoptosis, which was associated w...

T he issue of calcium (Ca) availability in alkaline, mineral soils has long been a matter of contention. Based on the commonly used ‘exchangeable cations’ test (ammonium acetate extraction), most Western soils are well supplied with Ca. However, in alkaline soils, a substantial percentage of ‘exchangeable’ calcium identified by this test can be in chemical forms not readily available to plants ...

In this study, we analyzed the modifications of antioxidant activity consequent to 3 typical home cooking practices (steaming, boiling, and microwave cooking) in fresh and home frozen vegetables. Six different vegetable species were examined: carrots (Daucus carota L.), zucchini (Cucurbita pepo L.), tomatoes (Solanumn lycopersicum L.), green beans (Phaseolus vulgaris L.), peas (Pisum sativum L....

The peppers which were treated at ice-temperature for 6 hours and 1 mmol/L spermidine for 10 min, followed by cold storage (4 ̊C ± 1 ̊C) respectively were investigated. The results indicated that the chilling injury was delayed and reduced by ice-temperature and spermidine treatments. Comparing with control group, ice-temperature and spermidine exerted significant effects on reduction of ascorbic...

STUDY OBJECTIVE To determine whether there is an effect on the prevalence of respiratory symptoms, an alteration in lung function, or an increase in the cough threshold to capsaicin among workers chronically exposed to hot chili (Capsicum) peppers. DESIGN Cross-sectional study of responses to a structured questionnaire, lung function assessed by spirometry and cough threshold to inhalation of...

• A UV-C treatment of 6 kJ m ?2 greatly enhanced the flavonoid accumulation in red bell peppers. UV-C+UV-B increased by ?94 % carotenoid content and UVB + C are good abiotic elicitors biosynthesis. Rutin is highly (?70 %) after UV treatments. stresses have beneficial effects plants inducing synthesis secondary metabolites when low doses were applied. The aim this study was to evaluate effect (B...
