(Bursa Uludağ Üniversitesi, 2019-11-28) Güvenç, Şaban; Fen Edebiyat Fakültesi; Biyoloji Bölümü
The aim of this study was to determine the effects of anthropogenic activities on the physiology of epiphytic lichens in Kirazlıyayla and Sarıalan picnic areas at Uludağ National Park. Chlorophyll a, b, carotenoids contents and OD435/415 ratio of all the species collected from Kirazlıyayla and Sarıalan were higher in picnic areas compared to the control areas. Chlorophyll contents of the samples collected from the picnic areas at the end of summer were higher than that of collected in early summer. Chlorophyll a content of Parmelia sulcata collected from Kirazlıyayla was lower at the end of summer than the value measured at the beginning of summer. The OD435/415 ratio of Evernia prunastri and Pseudevernia furfuracea samples collected from Kirazlıyayla, and Hypogymnia physodes and P. furfuracea samples collected from Sarıalan were higher in picnic area than the control area both in early summer and early autumn. Chlorophyll a was positively correlated with chlorophyll b, carotenoid, and OD435/415, and was negatively correlated with relative humidity and altitude. OD435/415 ratio was positively correlated with the other photosynthetic pigments, whereas it was only negatively associated with the altitude.

(Bursa Uludağ Üniversitesi, 2019-12-24) Turhan, Şule; Ziraat Fakültesi; Tarım Ekonomisi Bölümü
A review of Turkish agricultural history shows that dramatic changes have occurred in fruit and vegetable industry. It seems evident that changes will continue for the coming years. Especially developments of South Marmara Regions fruit and vegetable processing industry provide a good example for the agri-food sector. Today, consumer preferences drive markets. Reshape of the international agricultural trade is required due to, mainly, the globalisation of the markets. This will give growers more competition and the issues of marketing, international trade, environmental protection and government policies will be important factors for them. The aim of this study, it to examine the current situation of Turkish fruit and vegetable processing industry and highlight some points for the competitiveness of the industry. In general, Turkey tomato paste industry is a healthy sector directed to export markets, with some difficult years. Especially the decrease in production in 2010 caused an increase in the import.

Goji berry, Ginger and Ginseng are ancient Chinese herbs which have been used for thousand years as Traditional Chinese Medicine in China and other Asian countries as foods to promote good health and as drugs to treat disease. The keywords of Goji berry, ginger, ginseng, traditional Chinese medicine were searched in Google Scholar, Scopus, Research Gate and PubMed. The most important Goji pharmacological usages are improving function, enhances the bodys ability to adapt to a variety of noxious stimuli; it significantly inhibits the generation and spread of cancer cells and can improve eyesight and increase reserves of muscle glycogen and liver glycogen which may increase human energy and has anti-fatigue effect. Ginger has been widely used for arthritis, cramps, sprains, sore throats, rheumatism, muscular aches, pains, vomiting, constipation, indigestion, hypertension, dementia, fever and infectious diseases. Several pharmacological activities have been reported for ginseng extracts including effects on the central nervous system; antipsychotic action; tranquilizing effects; protection from stress ulcers; increase of gastrointestinal motility; endocrinological effects; enhancement of sexual behaviour; or synthesis of carbohydrates, lipids, RNA, and proteins. These versatile medicinal plants are unique sources of various types of chemical compounds which are responsible of the various activities of the plant. Traditional medicinal plants are cheaper, locally available and easily consumed as medicinal preparations and of course they are organic.
