In this article, p-substituted phenoxymethyl structure was introduced to the 1(C)-position of the imidazole ring by the reaction between o-phenylendiamine and the corresponding p-substituted phenoxymethyl acid which have attracted much attention in agriculture, biochemistry and pharmacology due to their antiviral, antimicrobial activities and phytohormone activities.[11-13] Then, the hydroxyethyl group was connected to the 1(N)-position of the imidazole ring using the N-hydroxyethylation reaction with 2-chloroethyl alcohol.

Each micro-shoot was separated from clumps and implanted in 1/2 MS medium enriched with IBA for checking the rhizogenic ability of phytohormone. The best root induction was obtained in 1/2 MS + IBA (1.0 mg/l) with an average of 18.90 [+ or -] 2.47 roots/shoot, where root lengths were 2.71 [+ or -] 0.17 cm within 2 week of culture (Table 3).
