Effects of different treatments on plant height, stem diameter, fresh weight and dry weight of tomato seedlings. (A) Plant height, (B) stem diameter, (C) fresh weight, (D) dry weight, 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).
