Ralstonia solanacearum is a causative agent of bacterial wilt and therefore poses serious threat to cultivated peppers (Capsicum annuum L.). Although attempts have been made control by grafting, the disease resistance mechanisms that protect grafted are poorly understood. Here, we grew composed rootstock Buyeding or Weishi scion Xinfeng 2. Following infection R. solanacearum, assessed differenc...

The yield of pepper with purple leaves (PF) is low, while the green (GM) not resistant to strong light and high temperature. In this study, we analyzed photosynthesis characteristics genetic stability their hybrid progenies using PF(CS3) GM(SJ11-3) as controls. Based on decreased color increased color, was divided into five groups: Z1, Z2, Z3, Z4 Z5. Results showed that increased, anthocyanin c...

Plants contain numerous polyphenols, which have been shown to reduce inflammation and hereby to increase resistance to disease. Examples of such polyphenols are isothiocyanates in cabbage and broccoli, epigallocatechin in green tee, capsaicin in chili peppers, chalones, rutin and naringenin in apples, resveratrol in red wine and fresh peanuts and curcumin/curcuminoids in turmeric. Most diseases...

Grafting favors the presence of bioactive compounds in the bell pepper, but many species and varieties have not yet been analyzed in this sense, including commonly grafted varieties. The aim of the present study is to characterize the content in β-carotenes, vitamin C, lycopene, total phenols, and the antioxidant activity of bell pepper (Capsicum annum L.) using the cultivar/rootstock combinati...

Two on-farm commercial vegetable demonstrations were conducted in south-central Kentucky, along with three specialty melon observation plots in 2003. Grower/cooperators were located in Edmonson and Larue counties. The grower/cooperator in Edmonson County grew one acre of cantaloupes, marketed through Green River Produce Marketing Cooperative located in Horse Cave, Kentucky. In Larue County, the...

Three different calibration approaches were applied in HPLC/MS/MS using electrospray ionization for the determination of 14 diverse pesticide residues at different levels in a variety of food matrixes. This study was conducted as part of a 4 day training course for 17 chemists to learn the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) approach to pesticide residue analysis in foo...
