DPPH radical scavenging activity in tea seedlings on modulation of ethylene signaling. The scavenging ratios of DPPH radicals were determined from the detached tea seedling samples after treatment with the control (CK) or 100 μM ACC for 5 days. Data points are mean ± SD of three biologically independent experiments. Asterisks indicate significant differences from the control sample (P < 0.05; Student’s t test)
