From: Litter chemistry explains contrasting feeding preferences of bacteria, fungi, and higher plants

Relationships between seed weight and root growth of 14 target plants sown over 36 litter materials, either undecomposed (top) or decomposed for 180 days (bottom). Note logarithmic scale for seed weight. Data refer to mean growth of 10 replicates for each combination of target plant, litter species and age, as compared to the control (gray horizontal dashed line). Logarithmic fit is also reported in each panel, and symbolized with either continuous or dotted black line according to significant or not significant result, respectively.
