Study of bermundagrass (Cynodon dactylon L) allelopathy to cotton (Gossypium hinsutum L) when growing in a nutrient solution. A new approach

摘要

The influence of bermundagrass to cotton growth was studied in the research site of the Agricultural University of Athens, in summer 2003. A hydroponic system was employed to create an artificial environment, in which allelopathy could be separated from resource competition. At the end of the experiment, cotton growth was clearly inhibited when plants were growing adjacent to bermundagrass. This is in agreement with results previously presented where cotton growth was inhibited when plants were growing in soil. It appears that hydroponics is a very suitable method for allelopathy research, especially when taking into account that plant growth in the nutrient solution required significantly less time than in soil.
