From: Co-application of proline or calcium and humic acid enhances productivity of salt stressed pomegranate by improving nutritional status and osmoregulation mechanisms

Figure 5

Effect of Proline (Pro) and Calcium (Ca) as foliar application alone or incombination with humic acid (Hc) as soil application on (a) fruit pulp/peel ratio, (b) fruit TSS percent, (c) fruit firmness (kg/cm3) (kg/tree) of ‘Wonderful’ pomegranate trees grown under salt stress conditions. The different letters on the bars in each column represent significant difference at p ≤ 0.05; errors bars are standerd error of three replicates. Pro: 5 mM proline alone as foliar application; Ca: 1.5% Calcium as foliar application alone; Hc: 15 g humic acid as soil application alone; Pro + Hc: 5 mM porline and 15 g humic acid; Ca + Hc: 1.5% calcium and 15 g humic; Ctrl: control (non treated).
