Cyclic electron flow around PSI (CEF) and parameters derived from the dark-interval relaxation kinetic of ECS (DIRKECS) in the seedlings with or without apical buds. Five treatments in the seedlings with apical buds are as Fig.2, and six treatments in the seedlings without apical buds are as Fig.3. CEF (a), total proton motive force (pmf) (b), the proton gradient (ΔpH) (c) and the thylakoid proton conductivity (gH+) (d) were estimated from seedlings with apical buds, and pmf (e), ΔpH (f) and gH+ (g) were estimated from seedlings without apical buds. At least 6 different leaves from different seedlings were used for each treatment and data are means of three replicates. Bars with different letters indicate significant difference at P < 0.05 (Leas significant difference test)
