Key Points

This research aims to evaluate the biochemical and physiological responses of sensitive and resistant wild mustard biotypes to tribenuron-methyl herbicide.
Conducted a factorial experiment in a completely randomized design at Mohaghegh Ardabili University.
Evaluated resistant and sensitive biotypes of wild mustard at two growth stages and multiple herbicide doses.
Measured enzyme activities, proline levels, chlorophyll content, carotenoid levels, and dry weight.
Resistant biotype exhibited significant increases in alpha-amylase activity (up to 220%) under low herbicide doses (5-15 g/ha).
Notable accumulation of protective compounds like proline (185.45%) and carotenoids (110.65%) in resistant biotype.
Low herbicide doses provided effective control without inducing resistance, emphasizing the need for integrated weed management.

Analyzes biochemical responses to tribenuron-methyl in wild mustard biotypes, indicating management strategies.
