Figures
- Figure 1.
Survival rates of cuttings according to (A) cutting orientation (vertical and horizontal orientations) and (B) growth substrates (overburden, waste rock, and peat moss) (n = 8, mean ± standard error). Different lowercase letters indicate the presence of significant differences (Tukey test, p < 0.05).
- Figure 2.
Shoot production over time according to (A) cutting orientation (vertical and horizontal orientations) and (B) growth substrates (overburden, waste rock, and peat moss) (n = 8, mean ± standard error).
- Figure 3.
Final shoot production from cuttings planted vertically or horizontally in overburden, peat moss, and waste rock (n = 8, mean ± standard error). Black bars show horizontal cuttings; white bars show vertical cuttings. Different lowercase letters indicate the presence of significant differences (Tukey test, p < 0.05).
- Figure 4.
A) Total biomass, B) shoot biomass, C) root biomass, and D) root: shoot ratio from cuttings planted vertically or horizontally in overburden, waste rock and peat moss (n = 8, mean ± standard error). Black bars: horizontal cuttings; white bars: vertical cuttings. Different lowercase letters indicate the presence of significant differences (Tukey test, p < 0.05).
