Abstract:In order to study various concentrations of lead (0, 100, 200, 400 .M of Pb(NO3)2) on response of morphologic and physiologic two canola (Brassica napus L.). varieties (Hayola 308 and RGS003), experiment was conducted in hydroponic culture method and using of Hoagland solution in Biotechnology Laboratory of Agricultural and Natural Resources Research Center of Khouzestan in 2009. Results showed that increasing concentration of lead caused decreasing root length and tolerance index, and instead caused increasing prolin and protein values of shoot and root any two varieties. But decreasing length mean of root and lead tolerance index was more Hayola 308 than RGS003. Thus of physiologic view RGS003 in compare Hayola 308 is more tolerance than lead stress
