Figure 1

(A–F) Effects of foliar application SA and Zn and the physiological attributes in Celosia argentea var. cristata at 60th day after seedling transplanting. Vertical bars show standard errors of means of three replicates letters indicate significant differences (p < 0.05) according to Turkey's test. SA, salicylic acid; Zn, zinc.
