P_-1.0 in the table represents the significant difference between the slope and the theoretical value of 1.0, different lowercase letters indicate significant differences (P<0.05) between the different rainfall duration for biomass of each organ of Fraxinus malacophylla Hemsl seedlings. A: allometric relationship, I: isometric relationship. R² is the coefficient of determination, and P is the significance.
