Figure 1.

Effects of methyl jasmonate (MJ) on (a) turf quality and (b) leaf electrolyte leakage (EL) in perennial ryegrass under salt stress. Treatments with same letters for each sampling date are not significantly different at P = 0.05.

Figure 2.

Effects of methyl jasmonate (MJ) on (a) leaf malondialdehyde (MDA) content and (b) chlorophyll content in perennial ryegrass under salt stress. Treatments with same letters for each sampling date are not significantly different at P = 0.05.

Figure 3.

Effects of methyl jasmonate (MJ) on (a) leaf superoxide dismutase (SOD), (b) catalase (CAT) and (c) ascorbate peroxidase (APX) activity of perennial ryegrass under salt stress. Treatments with same letters for each sampling date are not significantly different at P = 0.05.

Figure 4.

Effects of methyl jasmonate (MJ) on (a) leaf indol-3-acetic acid (IAA), and (b) gibberellin A4 (GA4) of perennial ryegrass under salt stress. Treatments with same letters for each sampling date are not significantly different at P = 0.05.

Figure 5.

Effects of methyl jasmonate (MJ) on (a) leaf zeatin riboside (ZR) and (b) isopentenyl adenosine (iPA) of perennial ryegrass under salt stress. Treatments with same letters for each sampling date are not significantly different at P = 0.05.
