Fig. 1: Effects of ethylene and JA on the senescence of rose petal discs.

a Color fading phenotypes; b color fading rate; c ion leakage rate; and d RhSAG12 expression levels in rose flower discs in response to ethylene, JA and 1-MCP treatment. ETH, 10 μL/L ethylene; JA, 100 μM MeJA; 1-MCP, 2 μL/L. The error bars represent the means of three biological replicates, and the letters indicate significant differences according to Duncan’s multiple range test (P < 0.05).
