The effect of weed extracts was examined on seed germination, proline, total protein and its profile in ten varieties of wheat. The % reduction in germination and protein was > 50% in all the varieties with all extracts however, positive effect was also observed. The proline was significantly stimulated in all varieties with all the extracts except PBW-154, PBW-343, PBW-443, RR-21 and UP-2382. The banding pattern of protein also influenced significantly. The SI was maximum between A. conyzoides x P. hysterophorus (52.2) in UP-2425 and minimum between A. conyzoides × M. alba (23.1) in PBW-154. On the basis of these parameters, PBW-373, PBW-443, UP-262 and UP-1109 were resistant and the inhibitory effect was maximum and minimum with P. hysterophorus and C. dactylon, respectively.
