To evaluate herbicide tolerance, particularly to imidazolinones, a provocative background is used with analysis of phenotypic changes and PCR diagnostics of mutations in the AHAS gene. When studying abiotic stresses, such as drought or cold, the tolerance index is calculated as the ratio of the dry weight of stressed plants to that of control plants.
Physiological markers of tolerance in Brassica napus include the assessment of electrolyte leakage, the accumulation of proline, soluble sugars, and proteins, as well as the activity of antioxidant enzymes and the level of relative water content in leaves. Disease tolerance is determined based on scoring scales of tissue damage.
