Abstract
Little information is available concerning morphological responses of Lolium perenne cultivars (Numan and Speedy green) to salinity and trinexapac-ethyl treatment in initial growth. In order to evaluate the effect of salinity treatment (0, 2000, 4000 and 6000 mg/lit) and trinexapac-ethyl levels (0, 50, 100 gr/ha) on morphological responses of 'Numan' and 'Speedy green' in initial growth stage, an experiment was conducted in a factorial experiment based on completely randomized design with three replications. Sodium chloride levels significantly affected shoot and root length, but no significant trinexapac-ethyl treatment was found in initial growth of Lolium perenne cultivars. Trinexapac-ethyl and salinity treatment has no intraction effect in initial growth of this two cultivars. Lolium perenne performance was not affected by trinexapac-ethyl in all concentration in initial growth of this experiment when irrigated by salinity water.
