Quality assessment and nutrient uptake and utilization in Luohan pine (Podocarpus macrophyllus) seedlings raised by chitosan spraying in varied LED spectra
Fig 5
Concentrations of nitrogen (N) (A, B, and C) and phosphorus (P) (D, E, and F) in parts of shoot (left), root (middle), and whole plant (right) in Podocarpus macrophyllus seedlings exposed to chitosan (+Cos) or water (+Water) sprays in three types of light-emitting diodes spectra from red, green, and blue lights.
Bar height corresponds to the mean of the measurement while the error bars represent standard errors. Different letters represent difference at significant level of 0.05 by Tukey test.
