such as singlet oxygen. Vitamin B6 is also the
master vitamin in processing amino acids and
plays an important role in developing proteins
specifically designed to help chloroplasts, thylakoid membranes, photosystem I, and photosystem II to function properly.
MANNITOL
The antioxidant mannitol has the ability to
protect and quench two damaging free radicals:
singlet oxygen and hydroxyl. Singlet oxygen is
damaging because it can react with proteins, pigments and lipids and is thought to be the most
important species for light-induced loss of photosystem II activity, as well as the degradation of
the D1 protein. It has been demonstrated that
when mannitol is present in the chloroplasts, it
can protect plants against oxidative damage by
the hydroxyl radicals.

MANGANESE AND MAGNESIUM
Both of these nutrients are attached to the
chlorophyll molecule that's located inside the
chloroplasts. These two nutrients play a part in
making turfgrass greener by helping develop
chlorophyll. They also transport other vital nutrients and are responsible for many enzymatic
functions and help prevent chlorophyll degradation in the cells.
CARBON
There's new evidence carbon plays a role in
the development of the turfgrass plant leaf, and
that a reduction in carbon reduces photosynthetic
activity, which reduces carbohydrate availability
to the turfgrass plant. There's also new evidence
to suggest proper development of the turfgrass
plant can't occur without proper amounts of carbon in the chloroplast. There's more evidence to
suggest that, if there's an abundant source of carbon in the thylakoid membranes inside the
chloroplasts, it can be mobilized for use as an energy source during senescence.
HUMIC ACIDS
Humic acids are another compound that
contain antioxidant properties that promote the
scavenging of free radicals. The added benefits
of humic acid are that they increase the availability of micronutrients, phosphate and potassium to the plant and enhance the chlorophyll
content of turfgrass.
Humic acids also stimulates root initiation because of the auxin-like activity they contain, which
is most likely because of their ability to inhibit indoleacetic acid oxidase breakdown. n
