= Where: = Retention time at the peak apex. = RT of peak end at 10% of peak height; = RT of peak start at 10% of peak height; Asymmetry factor The asymmetry factor is a measure of peak tailing. It is calculated when a user selects Evaluate Tailing in EasyID. It is defined as...
and the total leaf area of each plant. The roots of each plant were removed to measure the fresh and dry mass of the roots. The leaves were separated from the stem. The length of the stem was measured from the base of the stem to the apex. Fresh leaves were counted for each plant,...
This study uses the agricultural policy environmental extender (APEX) model and the global hydrological watershed unit and selects the Huaihe River watershed as a case study to describe the methodology.
