Cytogenetic effects of fungicide applications on meiosis of tomato (Lycoppersicon esculentum Mill.)

Abstract

Bu çalışmada Lycopersicon esculentumMill.’in (Familya: Solanaceae) mayotik kromozomları üzerine Agri Fos 400 (400 g/l mono ve di-potassium phosphonate) fungisitinin sitogenetik etkileri incelenmiştir. 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.

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 esculentumMill. (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.
