● Introduction：

Typical working concentration of 2,4-D is varied by application and plant species. It has been reported that soybean treated with 2,4-D at concentrations between 5.0 and 10 mg/L stimulated callus growth, while at a much lower concentration such as 0.5 mg/L stimulated new cell formation and cellular enlargement for tobacco callus tissue.² Other concentration such as 1-3 mg/L of 2,4-D has been reported to be effective in inducing callus formation of broad-leaf plants.¹ Additionally, 2,4-D is often used together with IAA and L-tryptophan for callus induction and suspension cultures of wheat, pearl millet and rice.²  2,4-D has also been used in seed testing for the detection of Phoma lingam on Brassica spp when incubated on a blotting paper that has been soaked with 0.2% 2,4-D solution.³
