FIGURE 15.2 Effect of treatment with retardants (SADH, PB) and auxin (IAA) on
potassium content in fruits, seed, and leaves of Double Red McIntosh apples.
Figure concerning on experiments 1, 2, 3 signed with the same letter don’t
differ significantly at P = 0.05 t Duncan’s test; n.s. means no significant
difference between treatments.
