Abstract
Acetolyzed exines of Juniperus communis extracted with hot 2-aminoethanol were prepared for electron microscopy. The strongly osmiophilic, homogeneous exine first becomes granular. With further extraction, granules are observed to surround unstained polygonal regions. The connections between granules are then broken leading to compound polygons, open polygons, and finally detached pieces. Orbicules and exine-1 are completely removed. The pattern of structural change is similar to that observed in Lilium longiflorum and in Fagus sylvatica.This publication has 2 references indexed in Scilit:
