摘要

The stability of 4,4,4-trifluoro-3-(indole-3-) butyric acid (TFIBA) were examined. Elongation of rice seminal root was promoted approximately 80% by continuous supply of 10-5 molL~(-1) TFIBA. Such promotion effect on root elongation is not found in IAA or IBA. The promotive effect of TFIBA on root elongation was not reduced by either direct heating in a microwave oven or autoclaving at 121?C for 15 min and root elongation was promoted by 70 - 80% at the concentration of 10~(-5) mol L~(-1). The effect of TFIBA was not lost by heat of microwave oven or autoclave. Although the effect of TFIBA dissolved in water was gradually lost at 30C in the light, it was maintained at 4°C in the light and at 30°C in the dark. Consequently, aqueous solution of TFIBA can be stored at room temperature for at least 1 month when it is kept in the dark.
