KUTAHYA YORESiNDE YAYGIN YABANCI OTLAR UZERiNDE ALLELOKiMYASALLARIN HERBiSiT (OT OLDURUCU) ETKiLERi

Bu caltsmada, allelokimyasallardan juglon, katekol ve dopa'nin herbisito/arak etkileri sentetik herbisit o/an 2,4 -D ile karstlastirtlmtsttr.Kutahya'daki ekin tarlalannda en yaygin yabanci otlann; Sinapis arvensis,Cirsium arvense, Papaver rhoeas ve Lamium amplexicaule turleri oldugubelirlenmistir. Allelokimyasallarin etkisi bu turler uzerinde arasttrtlmtsttr.Aynca bugdayda allelokimyasallarin herbisit etkileri, sentetik herbisitlerden2,4 - D 'nin etkisi i/e karsilastinlmtsttr. Allelokimyasallardan katekol vejuglon 'un yabanci otlartn gelisimini ve klorofil icerigini onemli derecedeazaltugi fakat bugdayda cok olumsuz bir etkisinin olmadigt bulunmustur.Sonuc olarak jug/on ve katekol allelokimyasallannin herbisit potansiyelesahip olduklari ve doga! herbisit o/arak kullanilabilecekleri belirlenmistir.
