Quinclorac, an auxin-type herbicide, induces embryogenic callus and somatic embryogenesis of greater celandine (Chelidonium majus L.)

摘要

Quinclorac (3,7-dichloro-8-quinolinecarboxylic acid) is an auxin-type herbicides which was introduced by BASF Aktiengesellschaft in 1985. Quinclorac and 2,4-D applied to embryogenic callus and somatic embryo induction of Chelidonium majus tissue cultures. Embryogenic calluses and somatic embryos were not induced from both leaves and stems of C. majus using quinclorac and 2,4-D. The root source was only effective for both induction of embryogenic calluses and somatic embryos. Embryogenic callus and somatic embryos were induced from the intact root cultures of C. majus using quinclorac. Quinclorac at 0.5 mg L-1 was the most suitable concentrations for callus induction and somatic embryogenesis. Quinclorac successfully induced embryogenic callus and somatic embryos from tissue cultures of C. majus. In these results, we propose quinclorac as a new plant growth regulator for plant tissue culture.
