From: Silicon attenuates calcium deficiency by increasing ascorbic acid content, growth and quality of cabbage leaves

Figure 2

Ca accumulation in the aerial part (a) and root (b), Si accumulation in the aerial part (c) and the root (d) of cabbage grown under Ca sufficiency and deficiency, with (− Si) and without Si (+ Si). F test was applied: *(p ≤ 0.05) and **(p ≤ 0.01). The student t means comparison test was applied. Lowercase letters (a,b) indicate significant differences to calcium within the same level as Si (p < 0.05). Uppercase letters (A,B) indicate significant differences for silicon within the same level as Ca (p < 0.05). The bars represent the mean standard error. n = 5.
