Fig
-
7- The curve of concentration of CYTOZYME and growth of
cotyledons -
The growth regulators used in
the
experiment have different characteristics
-
ROOTS,
PGR4 and HZ63 are growth
promoters They directly stimulate
the tiller development, leaf enlargement and
high clipping
yield..
ROOTS
is more powerful than PGR4 and MZ63 in
stimulating
growth
of grasses..
BAYLATON, BANNER are growth
retarders
—
They retard the cell enlargement, make leaves fine and
short But they make leaf color dark even under the
low
fertilization, have high turf density and high resistibility to
disease, insects and drought.. Their requlative mechanisms and function are being
studied
CYTOZYME
did not have any effect on growth and appearance of grasses..
