The study contributes to the enhancement of knowledge about the behaviour of Trigonella foneu-graecum L. (fenugreek) plants with lead [Pb (NO3)2] and their combinations with plant growth hormone 28-homobrassinolide (28-HBL). The growth and biochemical parameters of Trigonella foenu-graecum L. plants subjected to lead toxicity were determined. Application of HBL might be improved plant biomass due to increase of photosynthetic pigments; this further induced the rate of photosynthesis in fenugreek plants. The biochemical parameters like carbohydrates, proteins and nucleic acids were found decreased in pb applied plants and the toxicity was inhibited by HBL at low concentrations. The results clearly demonstrated the ameliorating effect of HBL in mitigating the toxicity of pb in fenugreek plants.

Keywords: Fenugreek, growth, 28-homobrassinolide, lead toxicity
