Table 3 p-values of the fixed factors and average lengths for all growth traits in series W

Factor	Num D	Hypocotyl length				Root length
Factor	Num D	Day 3	Day 4	Day 5	Day 6	Day 2	Day 3	Day 4	Day 5¹	Day 6¹	Day 7^{1, 2}
(a) p-value
Dose	2	0.48	0.28	0.59	0.55	0.91	0.38	0.09	0.36	0.28	0.006
Volume	2	0.14	0.76	0.008	0.0004	0.13	0.004	0.0004	0.0008	0.001	0.01

a) For each trait, the p-values (Wald F-test) of the analyses after model (1) of the factors dose and volume and their interaction are shown. Significant results are printed in bold (p < 0.05). b) Means (mm) and standard errors (s.e.; by variance heterogeneity: minimum and maximum) are detailed. Treatments at a time point (in column) with no letters in common differ significantly (p < 0.05, Tukey–Kramer test). Significant differences between dose treatments at same volume level are shown in bold
Num DF numerator degrees of freedom
¹Variance heterogeneity was considered for the factor volume
²For variant 4 ml, root length at day 7 was not measured. Root length at day 6 was used to perform the statistical analysis at the end of the experiment
