Field experiments showed that AB could be used to increase fresh weight and photosynthesis. During the winter season, seedlings were treated with or without AB for one month. At the early spring season (Feb, 16, 2022), the fresh weight of the shoot parts was measured, and the representative third leaves were chosen and imaged (B). Meanwhile, photosynthetic parameters, including total chlorophyll (C), Pn (D), Gs (E), and Ci (F) were measured. The error bars represent the SD. The ** or *** indicate significantly different values (P < 0.01, P < 0.001 according to t test)
