Abstract:
BIOSIS COPYRIGHT: BIOL ABS. Specific wavelengths of light
required for expression of phytotoxic activity of S-23142
(N-(4-chloro-2-fluoro-5-propargyloxy)phenyl-3,4,5,6-tetra-hydrophthalimide)
and acifluorfen-ethyl (ethyl-5-(2-chloro-4-(trifluoromethyl)phenoxy)-2-nitro
benzoic acid) were determined in cotyledons of cucumber seedlings
using the Okazaki Large Spectrograph. Leakage of amino acids
from the cotyledons was measured as an indication of the phytotoxic
activity. The wavelength effects showed common major peaks
of activity at 550 and 650 nanometers and a minor peak at
450 nanometers for both herbicides, indicating a common primary
photoreaction. Concomitant application of DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea)
with S-23142 had little influence on the effective wavelengths
for S-23142 activity. Light of 450 and 650 nanometers was
relatively less effective in achlorophyllous tissue grown
in far red light than in green tissue. These results strongly
suggest that the phytotoxic action of
