Abstract
The cytogenetic e f f e c t s of two s - t r i a z i n e k terbutryn and ametryn on t h e m i t o t i c process ani chromosomes i n t h e r o o t s of x. -f aba have been ir Two methods of treatments have been applic e f f e c t s . In the first seeds were soaked i n c~nc cont a ining 1x10-~1, 1110-~81 and 1x10s~ol~ut~ io r herbiclde. In the second method r o o t s were dim ed w i t h conc ent r a t ions containl-ng ~x~o-~1xM10,. 1x10s~o l~u t~i o n s o f the he rbi c ide s . I n both cc e n t r a t i o n s were applied for 3, 6, 12, and 24 ho~ trol experimeat was c a r r i e d out i n which water WE replace s o l u t i o n s . This study also included thc these two compounds on meiosis, yield and chrornc C2 plants, For these s t u d i e s seeds were soaked ed above and planted and grown i n the f i e l d undc c o n d i t i o n s o f Vicla -f aba growth. A s the plant: flower buds were collected and fixed f o r meiotj ation and a f t e r maturation yield was measured. ained f r o m these plants were then geminated i n the e f f e c t s of the herbicides on the chromosome^ plants.
