THE GROWTH AND CHROMIUM CONTENT OF BANANA PLANT (Musa acuminata) CV. AMBON LUMUT IN CHROMIUM STRESS CONDITION

The plants that live in polluted Chromium (Cr) areas can experience a variety of disorders in the body. The disruption caused by Cr can cause damage DNA, proteins, photosynthetic pigments, and chloroplast ultrastructure of cell membranes. It can inhibit germination, photosynthesis, respiration, cell division and growth, resulting in lower yields. To find out how Cr stress influences to banana plants {Musa acuminata) cv. Ambon Lumut, the present research was conducted on the growth and content of Cr in banana plants. In this research, bananas was grown in-vitro with Cr concentrations of 0, 50, 100, 200 and 400 ppm in the medium. The results showed that Cr influenced of the growth and content of Cr in banana plants {Musa acuminata) cv. Ambon Lumut. It is likely that the greater the concentration of Cr in the medium was, the smaller the increase in weight was. Root-shoot ratio and Cr content in root and shoot tends to be greater by increasing Cr concentration in the medium.
