Fig. 2From: Use of fulvic acid-like compounds from pulp-derived black liquor for enhancing the selenium content of peanut budsEffects of PFA on the fresh weight of peanut (Arachis hypogaea L.) seedlings treated with different selenite concentrations on the 3rd day and 5th day after germination (S1-S6: 0, 5, 15, and 25 mg·L− 1 Na2SeO3, 15 mg·L− 1 Na2SeO3 solution containing 60 mg-C/L PFA, and 25 mg·L− 1 Na2SeO3 containing 60 mg-C/L PFA. The same as below). Letters above the bars indicate significant differences (P < 0.05). Vertical bars represent ± SD (n = 5).
