Different letters indicate significant differences, small letters among columns (Kruskal–Wallis test, P < 0.05), capital letters among rows (Mann–Whitney U test, P < 0.05).

^aData were calculated for both plants/pot

^bData were calculated for the stronger tomato plant/pot according to the root weight

^cData were calculated for the weaker tomato plant/pot according to the root weight
