Abstract

Glutathione (GSH) level, glutathione-S-transferases (GST's) activities and plant pigments contents were determined in shoot and root system of wheat (Triticum aestivum cv. Sakha 8) treated with eleven compounds from certain herbicide groups in field experiment to compare their effect on wheat physiology and biochemistry at different time intervals. This experiment was carried out at Agriculture Research Station, Alexandria University, Alexandria, Egypt. The herbicide groups were nitriles romxynil with two formulations), sulfonyl ureas (tribenuron-methyl and AC322-140), aryloxy phenoxypropionates FOP's (clodinafop-propargyl and dicolofop-methyl), phenylureas (isoproturon in three formulations) and phenylureas and other groups of herbicides (two formulations). The GSH content of wheat roots was increased with time intervals after treatments, sulfonyl urea and FOP's were superior in this respect followed by phenylurea and nitriles. The same trend in stem was observed with 3-4 times in GSH content. While GST's activities were highly increased in wheat root than in stem and the least in leaves due to herbicidal treatments. Herbicides had no effect on chlorophyll b (ch.b.) and carotenoides, while caused significant increase in ch.a.. FOP's and sulfonyl urea groups gave the highest increase in this respect
