The three cultivars with the greatest commercial root production also had the highest maximum values for A and the highest specific leaf area, indicating that these two parameters can be used to select for highly productive cultivars of A. xanthorriza.
Fine root production (FRP) was estimated as the differences between maximum (rainy season values) and minimum (summer season values) biomass values.
We extracted information from 24 published papers on QTLs controlling 29 root parameters including root number, maximum root length, root thickness, root/shoot ratio, and root penetration index.
Below-ground growth measurements included maximum root depth and maximum root spread, hereafter referred to as root depth and root spread.
We hypothesized that SOC, root biomass, and root production would increase, while root decomposition would decline with increasing soil moisture.
The maximum root zone storage is calculated considering the distribution of land cover and rooting depth.
According to their report, many QTLs for the weight of deep roots, maximum root length, root thickness, and root dry weight were located in the DRO3 region.
QTL for root to shoot ratio (R/S, violet), root number (RN, green) maximum root length (MRL, red), and root thickness (THK, blue).
We also estimated aboveground net primary production (ANPP) as well as coarse root production.
The differences in surface area between the PMs would have influenced the number of root initials and potential root production.
