This experiment was conducted to find out the effects of activated carbon ratios on the change in solution and growth response in ornamental hydro-culture. Epipremnum aureum were grown in four treatments, control(water 100%), W₄C₁(water 80%+activated carbon 20%), W₃C₂(water 60%+activated carbon 40%), and W₂C₃(water 40%+activated carbon 60%) for 6 months. The range of change in water level was the highest in control, and the lowest in W₂C₃. The solution pH was the lowest in control, and solution EC was the highest in W₂C₃. Plant height was noted in 25.74cm of W₃C₂, 24.98cm of W₄C₁, 22.10cm of control, and 21.53cm of W₂C₃, respectively, although it was not significantly different among treatments. However, as the treating activated carbon ratios increased, root length was shortened. Fresh weight of top and root were better in W₃C₂ of activated carbon 40%, but dry weight of top and root were higher in W₄C₁ of activated carbon 20% than the other treatment. Photosynthetic rate on the Epipremnum aureum grown hydro-culture solution was not observed statistical significant difference among treatments. The number of leaves were the highest in W₄C₁(water 80%+activated carbon 20%), and fallen leaves were the lowest in control(water 100%). Therefore, overall, it is recommended that the treating activated carbon ratios increased, growth response was better, but, W₂C₃ treatment have inhibited growth of Epipremnum aureum. The results obtained the suggest that the W₄C₁ of activated carbon 20% treatment is used to improve water level, pH, EC of hydro-culture solution and growth of Epipremnum aureum. |
