İlkay ÖZTÜRK ÇALI Department of Biology, Faculty of Art and Science, Amasya University, Amasya - TURKEY Received: 21.07.2008 Abstract: In the present study, the cytogenetic effects of the fungicide Agri Fos 400 (400 g/l mono- and di-potassium phosphonate) on meiosis of Lycopersicon esculentum Mill. (Family: Solanaceae) were studied. The fungicide was applied to tomatoes grown in greenhouse conditions at the dosage (400 ml/100 l water) recommended by the manufacturing company and double the recommended dosage (800 ml/100 l water). All dosages of the fungicide Agri Fos 400 caused various abnormalities in meiosis when compared with the control. This situation could lead to a decrease in the productivity of fruits.

Bu fungisit, sera koşullarında yetiştirilen domates bitkilerine üretici firmaca önerilen dozda (400 ml/100 l suya) ve önerilenin iki katı (800 ml/100 l suya) dozunda uygulanmıştır. Agri Fos 400 fungisitinin uygulanan tüm dozları kontrole göre polen mayozunda çeşitli anomalilere neden olmuştur. Bu durum meyve veriminde bir azalmaya yol açabilir. Anahtar sözcükler: Fungisit, Sitogenetik etki, Domates, Mayoz, Polen Introduction Modern agriculture and industry depend on a wide variety of synthetically produced chemicals, including insecticides, fungicides, herbicides, and other pesticides. Continual widespread use and release of such synthetics has become an everyday occurrence, resulting in environmental pollution (1). It was .
