Effects of Pb on the Growth Characteristics of Solanaceae Vegetables

FENG Gong-neng et al (Yancheng Institute of Technology,Yancheng,Jiangsu 224003)  
[Objective] The research aimed to discuss the accumulation law of Pb in Solanaceae vegetables and its effects on the content of chlorophyll.[Method] The pot soil with different concentrations of Pb were prepared to plant Solanaceae plants.The content of Pb at different parts of plants was determined by using atomic absorption spectrometry and the content of chlorophyll was determined by using the mixture solution method of acetone and ethanol.[Result] With the increasing of Pb concentration in soil,Pb content in the roots,stems and leaves of plants gradually increased.Pb content in various parts of green pepper and tomato was in the following order: roots stems leaves.Pb content in different parts of eggplant was in the following order: roots leaves stems.With the increasing of Pb concentration in soil,chlorophyll content in the leaves of plants gradually decreased.[Conclusion] Pb could be absorbed in plants and retained in different parts of plants and the content increased with the increasing of Pb content in soil.And Pb in plants could enter into human body through food chain and harm the human health finally.
