Effects of different treatments on photosynthesis of tomato seedlings. (A) Photosynthetic rate (Pn), (B) stomatal conductance (Gs), (C) intercellular CO2 concentration (Ci), (D) transpiration rates of leaves (E), NA, 5 mg·kg−1 NA; KF, 60 mg·kg−1 KF; NA + KF, 5 mg·kg−1 NA and 60 mg·kg−1 KF. Different lowercase letters denote statistical differences among treatments of tomato seedlings at the 5% level according to LSD test. Error bars above mean indicate standard error (n = 3).
