Abstract
The investigations for the effect of naphtalene acetic acid(NNA)in concentrations of 25; 100; 200 and 400 ppm applied at tillering stage, on the yield and some morphological-production properties of the rice plants(Oryza sativa L.) variety Biser-2 were carried out in a green house in a pot experiment. Parallel to the treated variants, a control variant was out and was treated with equal volume of distilled water. The investigations concentrations of NNA caused changes in the rice plants in respect to the number of productive tillers and leaves stem height, panicle length, number of productive and sterile grains in the main panicle during (15 and 30 days after treatment) and at the end of the rice vegetation. In plants sprayed with NAA the fresh and dry weight of the below soil mass (root) increased during and at the end of the rice vegetation. With the applied concentration of NAA the fresh and dry weight of the total above soil mass (stem, leaf and panicle) showed increase only 15 days after treatment, with tendency to decrease especially at the end of the vegetation.
