Regenerations of spikelets and pistils were successfully induced from callus derived from glumelle and lemma explants of wheat cultured on MS medium supplemented with warious exogenous hormones. The resuits showed that (1) supplement with 2.1-D 2 mg/L and 6-BAP 0.1 mg/L wasadvantageous to the formation of callus from the explants: (2) hormone combination of 2,4-D 1.0 mg/L and B-BAP 2 mg/L was beneficial to the direct regeneration of spikelets from both calli derived from the glumelle and the lemma respectiv...
