Post-flowering water extractable K content (A) and dehydrogenase activity (B) in Zygopetalum maculatum orchids potting media. Means with statistically significant differences (as per LSD, P < 0.05) are denoted by distinct lowercase letters within treatments. T1 = Distilled water (control = K0), T2 = 10 mg L−1 K (K10), T3 = 25 mg L−1 K (K25), T4 = 50 mg L−1 K (K50), T5 = 75 mg L−1 K (K75) and T6: 100 mg L−1 K (K100).
