Abstract

The effect of accumulation and phytotoxicity of lead in cells and tissues of rise (Oryza sativa L.) cv.biser 2 in conditions of soil applied Pb(NO3)2 , was investigated in four different concentrations (mM/l): 20; 40; 80 and 160. The toxic effects of used lead concentrations were confirmed in biosynthesis of chloroplast pigments. As a result of lead hard immobilization from soil and its accumulation in root cells which presented a solid barrier for its further transport in procambium zone, chlorotic manifestation were recorded in lower percent. The inhibitory effect of used lead is very low in production of crude proteins as well as sugar content of the end of vegetation, were haven' t balance in values in roots and aboveground parts with tendency for real translocation from root in panicle and grain.
