Effect of vacuum infiltration. Intact seeds were vacuum
infiltrated for three 5 -min periods with 10-3 M kinetin (1 ml
solution/seed). Seeds were plated on water or 10-3 M kinetin
in petri dishes and incubated for 7 days at 30 C. Seeds were
then dehulled by hand. Dehulled seeds were incubated for
an additional 7 days at 30 C in water.
