Figure 2.
Effects of plant growth regulators on (a) fresh weight variation, and (b) water balance in A. andraeanum cut flowers. Values are expressed as the mean ± SD (n = 3 biological replicates). Different lowercase letters indicate significant differences according to Tukey's multiple range test (p < 0.05). Treatments: CK1, base solution (20g·L⁻¹ Sucrose + 200 mg·L-18-HQ); CK2, distilled water; T1, base solution + 10 mg·L⁻¹ 6-BA; T2, base solution + 20 mg·L⁻¹ 6-BA; T3, 30 mg·L⁻¹ 6-BA; T4, base solution + 50 mg·L⁻¹ GA3; T5, base solution + 100 mg·L⁻¹ GA3; T6, 150 mg·L⁻¹ GA3.
