Nucleoplasmatic index in meristematic cells of maize (Zea mays L.) as a tool in environmental bioindication
Test plants of maize (Zea mays L.) were exposed in pot experiments to air pollution at different locations in Slovenia for one vegetation period. Root tips were collected from the field after the period of four months. Digital image analysis was made, and a nucleoplasmatic index was calculated from the meristematic root tip cells of different test plants. Statistical evaluation of data demonstrated changes in the nucleoplasmatic index, in the cell area and in the area of nuclei of the maize plants. Therefore, we conclude that the nucleoplasmatic index can be affected by air pollution, and it can be used as a tool in environmental bioindication.
