Table II. The plastoquinone (PQ) pool redox state in barley leaves.
Estimation of the fraction of reduced PQ was determined using OJIP transients. The results are means ± se (n = 4, each with four technical replicates), and different letters represent statistically significant changes (P < 0.05) using one-way ANOVA and Tukey’s multiple comparison test.
| Treatment | Fraction of PQH2 |
|---|---|
| Control | 0.27 ± 0.01 a |
| P deficient | 0.36 ± 0.02 b |
| P resupply | 0.28 ± 0.01 a |
