University "St.Kliment Ohridski" - Bitola, Scientific Tobacco Institute - Prilep, Republic of Macedonia The aim of the investigation was to evaluate morphological, production and qualitative traits of four newly created fertile inbred lines and their resistance to black shank disease (Phytophthora parasitica var. nicotianae), compared to the...
TSRC, Tob. Sci. Res. Conf., 2009, 63, abstr. 10 TSNA method comparison using UHPLC-MS/MS MATHIS J.A.; PO YING YEUNG Global Laboratory Services, Wilson, NC, USA. Method development and optimization was performed for the quantification of tobacco specific nitrosoamines (TSNAs) in tobacco leaf. The objective was to shorten run time and compare the new method to the previous method. The evaluation of method...
CORESTA Meeting, Agronomy/Phytopathology, Rovinj, 2009, AP 17 Characterization of TSNA content in cured leaf of dark fire-cured and dark air-cured tobaccos grown in KY and TN, U.S.A. in 2006-2008 NIELSEN M.T.; BENNETT C.B.; FUFA S.; HELTSLEY D.; FINCH J. U.S. Smokeless Tobacco Manufacturing Co., Nashville, TN, USA Tobacco specific nitrosamines (TSNA's) found in the cured leaf of dark tobaccos are formed by the nitrosation of secondary amine alkaloids during post-harvest stages of leaf production. While previous research has identified many factors, including...
