Abstract
This experiment was conducted to investigate biological activity of ABA and its analogues on barley shoot growth and peroxidase activity in barley seedlings. The treatments of 3.2 ppm (+)-ABA, 1.2 ppm (S)-(+)-ABA, 0.6 ppm ABA-methyl cinnamate ester compound (AC), and 0.08 ppm ABA-umbelliferone ester compound (AU) inhibited the growth of barley seedlings by more than 80% as compared with untreated control. The increase in barley shoot-inhibit activity of (S)-(+)-ABA became 3-fold than the activity of racemic ABA, and those of AC and AU higher than that of (S)-(+)-ABA by about 2.5 and 16 times, respectively. Peroxidase activities of barley shoots during the early growth stage were kept at a constant levels without ABA treatment, but in the treatment of racemic ABA, (S)-(+)-ABA, AC and AU increased the activities. Furthermore, the peroxidase activities increased as the higher concentration of ABA and its analogues were applied.
