Analysis of trace metal distribution in plants with lab-based microscopic X-ray fluorescence imaging

Table 2 (A) Results of one-way repeated measures ANOVA and (B) pair-wise comparison for differences in NPQ_{_i1} of the same area before and after X-ray exposure (n = 4)

(A) Repeated ANOVA, test of within subjects effect
		Sum of squares	DF	Mean square	F	Prob > F
X-ray treatment	Sphericity assumed	0.0804	1	0.0804	11.32322	0.04357*
Error (xray)	Sphericity assumed	0.0213	3	0.0071

(B) Pairwise comparison, Bonferroni test
	Index	Mean difference	Std. error	DF	Prob > \|t\|	95% LCL	95% UCL
Before/after X-ray treatment	0	− 0.2005	0.05958	3	0.04357*	− 0.39012	− 0.01088

NPQ__i1—complete non-photochemical quenching ((F_m − \( {\text{F}}_{\text{m}}^{{\prime }} \))/F_m) at the onset of irradiance phase (_i1) according to Küpper et al. [25]. Significant differences are emphasized with asterisks
