Effect of indoleacetic acid on the metabolic activity oftaraxacum root segments
- 1 Department of Botany, University of Karachi, Pakistan
Inoubation of thin slioes ofTaraxacum root segments in 3-indoleaoetic acid solutions enhanced the level of total proteins, RNA, DNA and a number of enzymes reaching an optimum at 0.01 mg 1-1. It has been shown that the auxin promotes the synthesis of DNA, again with an optimum promotion at 0.01 mg 1-1 IAA.
