Özet

The objectives of the study were to determine the contribution of stem reserves to grain filling in a triticale cultivar and lines under drought stress conditions created at post-anthesis stage by chemical desiccant application such as potassium chlorate (4%). The study was conducted with completely random block design replicated three times at Southern Marmara Region in 2005 and 2006. In this study, dry matter translocation (DMT- mg grain(-1)) dry matter translocations efficiency (DMTE-%), rate of grain weight reduction (RGWR-%), mean productivity (MP- kg ha(-1)) and seed yield tolerance (SYT- kg ha (-1)) were determined.
