Ultrastructure of the leaf cuticle in Cycas circinalis Linn
Keywords:Cycas circinalis, cuticular membrane, ultrastructure, cuticle development, Lipophilic bodies
The organization and development of the cuticular membrane (CM) in juvenile as well as mature pinnae of Cycas circinalis Linn. have been investigated under TEM. In the Juvenile pinnae the CM is very thin with faint structural organization, whereas in the mature pinnae the structural organization of the CM can be distinctly divided into three zones, i.e., a polylamellate zone, an amorphous zone and a reticulate zone. Stages of liberation and transportation of lipophilic secretion have also been observed.
