Table 6. Comparison of OJIP parameters measured with direct fast imaging in comparison to P&P with 30-s delay time.
The values represent the average and SE of an independent measurement on different plants. The values represent medians ± se (n = 4). Asterisks denote significant differences between the two groups according to the Mann-Whitney test (*P < 0.05, **P < 0.01, ***P < 0.001).
