PD11, P. dentata harvested in November; PS12, P. seriata harvested in December; PY12, P. yezoensis harvested in December; PY01, P. yezoensis harvested in January; PY03, P. yezoensis harvested in March.
All values are mean±SD in triplicates.
Different letters (^a-d) in the same column mean significantly different (p<0.05).
