Comparison of 4,4,4-Trifluoro-3-(indole-3-)butyric Acid Dissolved in Water and Dimethyl Sulfoxide as a Solvent on Root Growth of Rice

Article Preview

Abstract:

The effective dissolution method of 4,4,4-trifluoro-3-(indole-3-)butyric acid (TFIBA) to rice plant growth was examined. Elongation of rice seminal root was promoted approximately 80% by continuous supply of 10-5 mol L-1 TFIBA dissolved in water. The primitive effect of TFIBA dissolved in DMSO on root elongation was greater than that of TFIBA dissolved in water, and the length of root was significantly increased by 233% by treatment with TFIBA at 10-5 mol L-1, compared with that in untreated control seedlings. However, DMSO occurred increase of root weight and showed somewhat disadvantage about reproducibility of TFIBA effect. In contrast, the reproducibility of TFIBA effect was high in the solution prepared with water.
