Simultaneous test to aluminum tolerance and giberelic acid sensibility in hexaploid wheat

Abstract

In nutritive solution, six genotypes of hexaploid wheat, with known behavior in aluminum (Al) tolerance and giberellic acid (GA₃) sensibility, were tested. Two Al concentrations (zero and ten ppm) and three times of GA₃ introduction (no GA₃, GA₃ at the fifth day and GA₃ at the eight day of experiment) were studied in a 2 x 3 fatorial design. The results showed that this kind of simultaneous test is efficient, and that there is no interaction between these two factors. The treatments that best fitted to the waited genotypes behavior were those with ten ppm of Al and GA₃ introduction at the eighth day of experiment.
