Priming of pansy (Viola 3 wittrockiana, different
colours from the ‘Roc’ series, Novartis Seeds B.V.) and
pepper seeds (Capsicum annuum L., cv. Bell Tower,Novartis Seeds B.V.) was carried out by imbibing the
seeds until they reached the desired moisture content
of about 38% (fresh weight basis), after which they
were transferred to a rotating drum. Seeds were kept
in the drum for 3–4 d at a temperature of 20°C. At the
end of a priming treatment seeds were either dried in
one of the ways described below, or they received a
further incubation treatment.
