Measurements. After 9 days of treatment, the percentage
of seed germination, radicle length, and the percentage of
radicles that developed necrosis were established for each
GFFP disc by using a stereoscopic microscope at 30×
magnification. The germination percentage was determined
by scoring the number of seeds with an emerged radicle
through the seed coat as germinated in a total of 100 seeds per
disc. Radicle length was measured in 15 randomly selected
germinated seeds from each disc.30 Presence of necrotic areas
was assessed in 50 randomly selected radicles in each disc.
