SIMULTANEOUS TEST TO ALUMINUM TOLERANCE AND GIBBERELIC ACID SENSIBILITY IN HEXAPLOID WHEAT

In nutritive solution, six genotypes of hexaploid wheat, with known be havior in aluminum (Al) tolerance and giberellic acid (GA(3)) sensibil ity, were tested. Two Al concentrations (zero and ten ppm) and three t imes of GA(3) introduction (no GA(3), GA(3) at the fifth day and GA(3) at the eight day of experiment) were studied in a 2 x 3 fatorial desi gn. The results showed that this kind of simultaneous test is efficien t, and that there is no interaction between these two factors. The tre atments that best fitted to the waited genotypes behavior were those w ith ten ppm of Al and GA(3) introduction at the eighth day of experime nt.
