Figure 1.

Developmental events of E. pubescens plant (A) and changes of E. pubescens leaf size (B) and biomass weight (C) at five growth stages: Full flowering stage (FF), peak seed set stage (PSS), ripening stage (RS), and two timepoints of harvest stage (HS). The corresponding observations were made separately on 16 April, 10 May, 3 June, 27 June, and 21 July. Two investigations for harvest stage were carried out on 27 June and 21 July since E. Pubescens leaves are harvested usually in June by farmers and sometimes till July, depending on the actual growth status and place of E. Pubescens plants.
