Abstract
This study examined the modifications made to the root system architecture of Arabidopsis thaliana when subjected to an increase in population (biotic) and a decrease in nutrient concentration (abiotic). Population density was found to have significant effect on number of root hairs (p<0.05) while nutrient concentration was found to have significant effect on length of primary root and number of lateral roots (p<0.05). Furthermore the study showed that Arabidopsis thaliana modifies its root system architecture in response to different growing conditions separately but it did not show significant interaction for ‘population density x nutrient concentration’ in all response variables (p>0.05). This work could serve as a guideline when considering sowing density and fertilizer application to other crop species.
