A 2-year (2007 and 2008) open-field experiment was conducted to study the effects of irrigation on the yield parameters and main antioxidant components (lycopene, phenolic compounds, and ascorbic acid) of processing tomato. Two different treatments were applied: some plants were regularly irrigated, and some had their irrigation cut off 30 days before harvest. Both groups were compared with a rainfed control. Daily irrigation volume was calculated from the average daily temperature to reach optimum water supply. Fruits were harvested at the red-ripe maturity stage. The irrigated plants gave a significantly higher yield, and rainfed plants showed a yield loss. Irrigation had a greater effect on the average fruit weight than on fruit number. A seasonal effect was also remarkable, but was not as strong as that of irrigation. A better water supply caused a lower Brix number than that of the rainfed control. In both years, the antioxidant concentrations in tomato fruit showed a decrease with irrigation, except for the ascorbic acid content.
Dünya Sağlık Örgütü'nün tanımlamasına göre VKİ'nin 30 ve üzerinde hesaplanması obezitedir. Hem obezitenin kendisi hem de sebep olduğu insülin direnci Metabolik Sendrom kriterlerindendir. Bu çalışmada aile hekimliği polikliniklerine başvuran erişkinlerde obezite ve Metabolik Sendrom sıklığı ile ilişkili faktörlerin değerlendirilmesi amaçlanmıştır. Yöntem: Çalışmaya 18-70 yaş aralığında, medikal veya cerrahi obezite tedavisi almayan, gebe veya lohusa olmayan 201 kişi katıldı. Katılımcıların sosyodemografik bulguları, kronik hastalıkları, diyet yapma öyküleri sorularak kaydedildi. Boy, ağırlık, bel çevresi, arteriyel kan basıncı, açlık kan şekeri, trigliserid, HDL seviyeleri ölçülerek kaydedildi. Hem IDF hem de TEMD kriterlerine göre Metabolik Sendrom oranları belirlendi. Tüm antropometik ölçümler aynı ölçüm araçlarıyla yapıldı ve tetkikler aynı laboratuvarda değerlendirildi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
