Abscisic acid, or ABA, a
naturally occurring plant- hor
mone, is considered to inhibit
growth in a plant. ABA causes
closure of the stomates, the very
small openings on the surface of
the leaf. The stomates need to be
open to carry on photosynthesis,
which is perhaps the most process
on earth.
Scientists refer to a leaf as a
source, a place where something
originates. A sink is where
something is utilized, in this case,
the carbohydrates or sugars
produced by photosynthesis
originate in the leaves and flow to
the sink, which is usually the
developing seed.
"We know from our previous
research that ABA travels from
the leaf, where it is produced, to
the seed,” Brun said, "We want to
know if ABA travels passively with
the sugars just going along for
the ride or if has its own inside
track.”
"if ABA accumulates in the leal,
in effect the factory shuts down,”
he added. "It you have filling pods
that relieve the leaves oi some ot
the ABA, the leaves can carry on
photosynthesis longer.
"So far we have not investigated
whether other actively growing
sinks such as developing leaves,
root tips, axillary buds, or nodules.

which import large quantities of
carbohydrate, may also import
ABA.”
While ABA functions as an
inhibitor within the leaf, causing
stomatal closure, Brun said ABA
may have both inhibitory and
promotive effects in developing
seeds and other sink tissues.
FAIRFAX, Va. Most legumes
are very sensitive to soil acidity.
Alfalfa soils should be limed to a
pH of 6.5 or higher. Clovers and
birdsfoot trefoil are a little more
tolerant of soil acidity, but they
respond to a sound liming
program.
Soybeans are one crop that too
often has suffered by a neglect of
liming. Soybeans are very sen
sitive to low pH soils, and low or
mediocre yields often result from
an inadequate liming program.
Soybeans grown in rotation with
corn can be a particular problem.
The heavy amounts ot nitrogen
apphed for the corn crop are a
major cause of soil acidity. In tact,
tor each pound ot nitrogen applied,
about tour pounds ot limestone are
needed to neutralize the acidity
formed.

tune can have a big effect on
soybean yields.
As a last report, if the soil is acid
and it is tune to plant soybeans, try
drilling about 500 pounds per acre
of limestone with the beans,
recommends the National
Limestone Institute. This could
increase yields by several bushels
per acre. However, the best
practice is a sound liming program
well in advance of planting
soybeans. Q
