For phytomass, leaf area (LA) and basal area (BA), cumulative values for the five plants are given, for root:shoot ratio (RS), shoot length (L_shoot), root length (L_root), shoot and root length increment (LI_shoot, LI_root, in percent of initial value), basal area increment (BAI, in percent), and RGR, averages over the five plants are presented. Relative growth rates (RGR) are given in g g⁻¹ 450 d⁻¹. Different small letters indicate significant differences between diversity levels (p < 0.05); asterisks in the dry treatment indicate significant differences between moisture treatments in a diversity level (

^◦p < 0.10;

^*p < 0.05;

^**p < 0.01;

^***p < 0.001).

Note different no. of replicates in the diversity levels.
