Figure 2From: Contribution of soil esterase to biodegradation of aliphatic polyester agricultural mulch film in cultivated soils The isolation rate of the PBSA-degrading fungi and the degradation rate of the PBSA film. The scatter diagram shows the correlation between the isolation rate of the PBSA-degrading fungi and the degradation rate of the PBSA film in different soils. P represents the significance, and ρ represents Spearman's correlation coefficient. Degradation rate (%) is the average degradation during the first 3 weeks (ratio/week).Back to article page
