After the examination of each species, measurements were done for colpus length and thickness, pore length and thickness, pollen shape, exine thickness, intine
thickness, polar axis length, equatorial axis length of pollen.
In contrast, the pollen inner wall called intine
, that covers the protoplasm, is delicate with low resistance, composed of cellulose and pectin.
Also, Mert (2009) investigated the pollen length pollen width intine
and exine thickness of six cornelian cherry (Cornus mas L.
Datura stramonium showed the highest intine
Thick and hard extine with spike and deposit of sporopollenin began to grow from the outside of the thin and soft intine
Pollen grains possessing a much-reduced exine and elaborated intine
(omniaperturate and/or exineless) are known to occur in 54 families of angiosperms and are nearly ubiquitous in Zingiberales (Kress, 1986).
Three different electron- dense layers form the pollen grain wall: ectexine with interrupted tectum, columellae and foot layer; endexine and intine
still in formation.
Si tenga presente, intine
, che agli studenti e stato chiarito esplicitamente che il lavoro non sarebbe stato sottoposto a verifica formale, (6) ne avrebbe influito sul voto finale del corso.

The inside layer of the pollen grain, the intine
, is not as resistant and is composed of cellulose and pectin produced by the microspore cell.
is also continuous and its inner border is irregular.
