Ethephon’un Tritikale’de Tane Verimi, Protein Oranı ve Protein Verimine Etkisi

This research was conducted at the Experimental Field of the Department of Field Crops, Faculty of Agriculture, Ankara University between 2004-2006 in order to determine the effects of different ethephon doses applied at the various growth stages on grain yield, protein content and protein yield of triticale. Tatlıcak 97, Melez 2001 and Karma 2000 cultivars of triticale were used as study material and 0, 200, 400 and 600 g/ha ethephon doses were applied in the growth stages of jointing, before heading and the end of anthesis. According to the results of the research; significant differences were determined with the application of different doses of ethephon and at various growth stages on three triticale cultivars in grain yield, protein content and protein yield. The highest grain yield was obtained at the treatment applied before heading with 600 g/ha ethephon dose. Depending on years, the greatest protein content was generally determined with the treatment applied at jointing with 600 g/ha ethephon dose. Grain yield directly affected protein yield and the highest protein yield values were observed at 600 g/ha ethephon dose with the treatment of before heading. In conclusion, it will be possible that lodging can be decreased, and grain yield and protein yield dependent on grain yield may be increased with the use of ethephon in triticale.
