Fig. 8From: Physiological mechanism of strigolactone enhancing tolerance to low light stress in cucumber seedlingsEffects of exogenous GR24 on the enzyme activities of APX (A), GR (B), DHAR (C) and MDHAR (D) in cucumber seedlings under low light stress. Note: The respective parameters were measured at 7 days after the start of low light stress and/or 10 μM GR24 treatments. Each histogram represents the mean value of three independent experiments, and the vertical bars indicate SEs (n = 3). Different letters indicate significant differences at P < 0.05, according to Duncan’s multiple range tests. Cont, 0 μM GR24 + 500 μmolm− 2 s− 1 PPFD; Cont+GR24, 10 μM GR24 + 500 μmolm− 2 s− 1 PPFD; LL, 0 μM GR24 + 60 μmolm− 2 s− 1 PPFD; LL + GR24, 10 μM GR24 + 60 μmolm− 2 s− 1 PPFD. Here, APX, ascorbate peroxidase; GR, glutathione reductase; DHAR, dehydroascorbate reductase; MDHAR, monnodehydroascorbateBack to article page
