3.2. Effect of plant hormone treatments on vitamin C
MeJA treatment led to a significant decrease in vitamin C level
compared to the control at 1 d. Afterwards, no significant difference
was observed between MeJA treatment and the control. ETH and 1-
MCP treatment did not exert obvious effect on the content of vitamin
C except that ETH treatment induced a significant increase in vitamin
C content 3 d after treatment. The content of vitamin C was signifi-
cantly reduced by SA/SA and Control/SA treatments after 3 d, but
SA/Control treatment did not influence the content of vitamin C
(Fig. 2).
