摘要:

【Objective】The physiological role of the sodium humate in imparting resistance to heavy metal stress in wheat seedlings was explored by applying sodium humate in cadmium (Cd) stressed soil. 【Method】Different methods of sodium humate application, viz., seeds soaking, irrigation and soil amendment were used to stndy their effects on growth and development of wheat seedlings under Cd stress conditions, and the absorption and accumulation of Cu, Zn, Fe, Mn and Cd were investigated. 【Results】The application of sodium humate promoted the growth and development of wheat seedlings, relieved the toxicity of Cd and increased the dry matter accumulation in wheat seedlings. Amendment of sodium humate with soil gave the best results. Different modes of soidum humate application significantly reduced Cd accumulation in wheat seedlings and promoted the absorption and accumulation of Cu, Zn, Fe and Mn. The efficiency of different application modes reduced gradually with increase in severity of Cd stress. 【Conclusion】The studies revealed that application of sodium humate increased the yield of wheat by providing tolerance to Cd toxicity, therefore, it may be used as eco-friendly soil amendment in Cd stressed soils for sustaining productivity.
