Anatomy Structure of Pericarpium and Pome Fruit

Abstract

Research on anatomical structure of pericarpium and pome fruit have not been done yet. The aim of this study is to know the anatomical structure from pericarpium and pome fruit. The sample for pericarpium fruit is apple and pear, while tomato and orange are used for the pome fruit sample. The anatomical structure were observed microscopically using transverse and longitudinal slices of the developing pericarp. The results of this study indicated the presence of stomates on the epidermis tissue and is founded epicarp of pome fruit. Another anatomical structures are supporter tissue i.e. sclerenchyme with lignified sclereides in it, and parenchyma with pigmentation. The anatomical structure of epicarp on pericarpium fruit consisted of epidermis cell, parenchyma cell and secretory cells. Mesocarp of four kinds of fruits consisted of parenchyma tissues that each of the cell contained starch grains with pigmentation (antosianin) and ergastic compounds.  There are ergastic compounds i.e. crystal, and atsiri oil substances. Antosianin can be found in apple and tomato fruit skin, whereas pear and orange fruit contained more ergastic substances. The invention from the anatomical research can be associated for the function and the advantage from the plant or something special that affected by adaptation pattern.
