SUMMARY The invasive weed species have been found among the most important threats to the native vegetation during recent times. The recent climate changes, particularly the increasing atmospheric CO2 levels are supposed to enhance the growth of invasive weed species. We evaluated the effect of ambient (current normal level of CO2 in the atmosphere) and simulated (elevated to double of normal CO2 in the atmosphere) CO2 levels on the invasive weed species Potentilla recta L. The invasive weed species was grown under normal (~400 ppm) and elevated (~800-850 ppm) CO2 in a controlled glasshouse. The data on fresh weight, dry weight, number of leaves, plant height and chlorophyll index were recorded. The results of the studies indicated that the elevated CO2 levels increased the growth of P. recta. The high levels of CO2 increased the fresh weigh, dry weight, plant height and number of leaves of P. recta compared with ambient CO2 while chlorophyll index was not affected. In conclusion, the increasing CO2 levels in the atmosphere can increase the growth, and hence the invasiveness of the invasive weeds species. Further, the generation of such information is very important for devising management strategies of invasive weed species.
