Fig. 5.
Sex-related differences in the diurnal variations in levels of α-tocopherol quinone (α-TQ), given both per g of dry weight (DW) and per unit of chlorophyll (Chl) a+b, and the oxidation state of α-tocopherol (estimated as α-TQ/α-Tt, where α-Tt = α-T + α-TQ) in Pistacia lentiscus during winter (25 January) (this figure is available in colour at JXB online).
Data represent mean ± SE of six individuals. Significant differences between groups were tested by two-way factorial analyses of variance (ANOVA) with time and plant sex (females vs. males), shoot (R, reproductive; NR, nonreproductive), or fruit (shoots with and without fruits) as factors. Asterisks indicate significant differences between males and females, R and NR shoots, or shoots with and without fruits at a given time point (Student’s t-test, P < 0.05). NS, not significant (this figure is available in colour at JXB online).
