↵a Formation of a local primordium at the radial position of treatment.
↵b Formation of an incomplete ring-shaped primordium or several individual bulges.
↵c Formation of a complete ring-shaped primordium.
↵d Primordia were always formed at the flank above the site of treatment at the same radial position as IAA application.
