The first sign of flower induction which is characteristic of the Saccharum species, i.e., plant elongation, was observed at 60 days after the beginning of the flower induction treatment, indicating that the genotypes responded to the treatments. Among the tillers of the same genotype, in Treatments I (30 s) and II (45 s), some were etiolated leading to a visual lack of uniformity compared to treatment III (1 min).
