EFFECTS OF CADMIUM STRESS ON ROOT TIP CELLS AND SOME PHYSIOLOGICAL INDEXES IN ALLIUM CEPA VAR. AGROGARUM L.

摘要

Allium cepa var. agrogarum L. seedlings grown in nutrient solution were subjected to increasing concentrationsof Cd2+(0, 1, 10, 100 μM). Variation in tolerance to cadmium toxicity was studied based on chromosome aber-rations, nucleoli structure and recons
