Comparison effects of 1-MCP and salt levels on net photosynthesis rate, Pn (A–D) and SPAD values (E–H) of rice flag leaves in 2016 and 2017. Values are denoted as mean ± SE (Pn, n = 3 and SPAD, n = 5). Values followed by different letters are significantly different (p ≤ 0.05) according to the LSD test. Where treatments are Control (CK), Low Salt Stress (LS), and Medium Salt Stress (MS), while CT = no 1-MCP treatment and 1-MCP = 1-MCP treatment. Liangyoupeijiu (LYP9) and Nipponbare (NPBA) are rice cultivars. P-values of the two-way ANOVAs of 1-MCP, salt stress, and their interaction are indicated: ns, not significant; P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001. Bars with the same letter are not significantly different in the LSD test.
