Cornus mas samples may represent a novel dietary source of valuable α-linolenic acid from n-3 PUFAs family. The major PUFA was linoleic acid (C18:2 9c12c): 7.93 (in leaves) – 60.18 g.100 g -1 of oil (in seeds) the second most abundant was α-linolenic acid (C18:3 9c12c15c), especially in leaves and flowers (24.59–30.22 g.100 g -1 of oil, respectively). Lipid fraction was extremely rich in PUFAs: 32.52–61.86 g.100 g -1 of oil. Among MUFAs oleic acid (C18:1 9c) 3.25–19.61 g.100 g -1 of oil dominated, with the highest content in fruits. SFAs were represented by palmitic acid (C16:0) 10.87–32.20 g.100 g -1 of oil. The application of GC enabled detecting 14 fatty acids in lipid fraction extracted from Cornus mas samples, belonging to all groups. Leaves proved to be extremely rich in carotenoids, mainly β-carotene (88.5 mg.kg -1) compared with the rest of the plant. Cornus mas contained a substancial amount of lipids (3.34–5.23%, except fruits). Protein content (2.27–10.58%) was generally higher than in many wild or cultivated fruits, while flowers were distinguished by the highest content (10.58%), as compared with other studied parts of this plant. The most importantly, it was concluded that the contents of studied nutrients differed significantly (p <0.05) depending on the morphological part of plant. Cornell University Press, Ithaca, NY.The aim of this study, focused on the nutritional value of different morphological parts: leaves, flowers, fruits and seeds of Cornus mas L., was to determine the contents of essential nutrients, fatty acid and amino acid profiles, and the content of selected elements. The American Phytopathological Society, St. Laboratory Guide for Identification of Plant Pathogenic Bacteria. florida in the northwestern United States (2) however, this is the first report of P. Samples of the bacterium were sent to Texas A&M University, College Station, for fatty acid analysis, and the results confirmed the identity of P. The bacterium had a positive reaction to the Levan test and negative reactions to potato rot and arginine dihydrolase tests and was identified as Pseudomonas syringae (1). The bacterium was reisolated from inoculated plants, was characterized as gram-negative and rod-shaped, and produced fluorescent pigment on King's medium B agar. A bacterium was isolated from infected plants and tested for pathogenicity on C. Disease symptoms were restricted to early spring during wet and cool weather later in the season new growth was free of symptoms. These lesions eventually coalesced to form large dark necrotic patches that covered a large portion of the leaf or the entire leaf. In early stages, leaf infection consisted of discrete lesions, angular in shape and surrounded by a chlorotic halo. The disease affected mostly leaves and young shoots, causing dark brown necrotic lesions and some die back. mas plants within the nursery and has caused severe damage for three consecutive years. In Tennessee, a leaf blight was first observed during spring 1996 in nursery plants imported from Europe. Cornellian cherry has demonstrated longevity and adaptability and has had no previous disease or pest problems. Cornellian cherry (Cornus mas) is an enduring dogwood that is primarily grown as an ornamental plant in North America, but in parts of Europe, its fruit is eaten fresh or pickled or made into soft drinks, wine, and liqueur.
