Anatomical Changes In Roots Of Cicer arietinum And Glycine max Crops In Response To Industrial Waste Water Treatment

Jyoti Kumari Meena Regularly growing industries and urbanization results into contamination of agricultural land. They are main sources of heavy metals which lead to one of the major constraints to crop productivity and growth. The present research is designed to evaluate the effect of industrial waste water irrigation on specialized root anatomical features, such as outer epidermis,cortical cells, endodermis and the root vascular tissue, which are often related with heavy metal tolerance in crop plants. The industrial waste water used for irrigation of crop contains various heavy metals like As, Cd, Pb, Zn, Fe and Ni. Arsenic (As), Cadmium (Cd) and Lead (Pb) concentrations in industrial waste water were higher than the permissible limits given by WHO and BIS.The high concentration of As, Cd, Pb affected the root epidermis, the cortex cells, and the xylem vessels. Anatomical study of longitudinal sections of roots of both plants Cicer and Glycine showed thick cell wall deposition in outermost layers of roots of both plants.Quiescent center(QC) is absent in both crop plant irrigated with industrial waste water as contrary to control plants. Lack of QC in these plants may be a defense mechanism to protect the root apical meristem from heavy metal stress conditions by retaining the viability and function of the QC cells.

KEY WORDS : Anatomical study, Cicer, Glycine, Root.
