Abstract (2. Language): 
In this study, the effect of a fungicide know as Switch 62.5 WG (% 37.5 Cyprodinil+% 25 Fludioxonil) pulverised on tomato (Lycopersicon esculentum Mill.) plant grown in pots in under greenhouse conditions on the amounts of photosynthetic pigments, protein, indole-3-acetic acid and abscisic acid [(IAA)and (ABA)] known as plant hormones was examined. Applications of Switch 62.5 WG were used as recommended dose (60 g/ 100 l tap water) as given on the label, as well as two fold higher (120 g/ 100 l tap water) and three fold higher (180 g/ 100 l tap water) doses. Results showed that the values of photosynthetic pigments were increased in fungicide application groups except for 180 g/ 100 l of Switch 62.5 WG when compared to the control group. The values of protein, IAA and ABA were also increased in all fungicide concentrations. Since the amount of ABA was increased in all application groups of Switch 62.5 WG in accordance with its application doses, it was concluded that the fungicide has exerted physiological stress in tomato plants.

Abstract (Original Language): 
Bu çalışmada; sera koşullarında saksıda yetiştirilen domates (Lycopersicon esculentum Mill.) bitkisine uygulanan Switch 62.5 WG (% 37.5 Cyprodinil+% 25 Fludioxonil) fungisitin bazı fotosentetik pigmentlerinin, protein ve bitkisel hormonlardan indol-3-asetik asit ile absisik asit [(IAA) ve (ABA)] miktarları üzerine etkisi incelenmiştir. Switch 62.5 WG fungisit uygulamaları; etikette önerilen (60 g/ 100 l çeşme suyu), önerilenin iki katı (120 g/ 100 l çeşme suyu) ve önerilenin üç katı (180 g/ 100 l çeşme suyu) dozlarında yapılmıştır. Switch 62.5 WG'nin 180 g/ 100 l dozu dışındaki diğer uygulama gruplarında, fotosentetik pigment maddelerinin değerleri kontrole göre artmıştır. Protein, IAA ve ABA miktarları tüm fungisit konsantrasyonlarında kontrole göre artış göstermiştir. Switch 62.5 WG'nin tüm uygulama gruplarında ABA miktarının kontrole göre doz artışına paralel olarak artması nedeniyle uygulanan fungisitin domates bitkisinde fizyolojik strese neden olduğu görülmüştür.
