Altered root elongation under exogenous ABA treatment. Seeds of wild type and mutants were grown on 1/2 MS media for four days and then were transferred to MS agar media containing 0 or 2 μM ABA. The picture was taken and the root length was determined at the 7th day after the transfer. The relative root length was the ratio of average root length of seedlings in 2 μM ABA medium to those in 0 μM ABA medium. Standard errors were calculated from three independent experiments, every of which employed more than 25 seedlings of each genotype. Groupings were based on Student-Newman-Keuls Test, a = 0.05.
