Method |
"Three
varieties
of
Nicotiana
tabacumn
L.
were
used
for
studies
on
leaf
ontogeny-i.e.,
Havana
Seed,
Cash,
and
Cuban
Shade.
The
tips
of
half-
grown
plants
were
removed
at
various
times
of
day
and
night,
some
being
placed
in
formal-acetic-alcohol
and
others
in
Bouin's
solution.
Still
others
were
dissected
out
under
a
binocular
microscope
while
still
fresh." |
Comments |
"The
thickness
of
some
300
leaves,
borne
at
various
levels
on
the
stalk,
and
grown
under
sun
and
shade
conditions,
averages
235
microns.
The
lamina
is
thickest
just
out
from
the
midrib,
about
midway
between
the
base
and
tip
of
the
leaf.
The
thinnest
portion
is
near
the
base." |
