Heavy metal content in normal green and chlorotic plants of sugarcane

Study conducted to elucidate heavy metal status in various morphological components of normal green and chlorotic plants of sugarcane variety CoLk 8102 indicated that chlorosis induced significant variation in Pb and Cr contents. Morpho-physiological components did not differ significantly with respect to any of the heavy metals. There was a marginal increase in transport index of heavy metals in chlorotic plants. Although chlorosis induced significant variation in Pb and Cr contents, on overall basis the partitioning of heavy metals followed a trend similar to that of partitioning of dry matter. The lead content was somewhat higher in the chlorotic plants as compared to the normal green plants on per unit plant weight basis.
