Allelopathic potential of bidens pilosa on (germination percentage, hypocotyl length, and root length of raphanus sativus (radish).

This study investigated the effects of three concentration of Bidenspilosa aqueous extracts on Germination Percentage, Hypocotyl Length, and Root Length of Raphanussativus (radish).

A total of 500 seeds was used, 240 seeds for the experimental groups and 60 seeds for the control group. The seeds were treated with 5 mL of solution and the control group also received the same volume of distilled water. The emergence of the radicle indicated the occurrence of germination. The germinated seeds were allowed to grow for another 24 hours to measure the effects of the extracts on Hypocotyl Length and Root Length. Seeds that failed to germinate after 24 hours were inspected for germination after 48 hours.

Results show that Bidenspilosa aqueous extract has allelopathic potential on Germination, Hypocotyl Length, and Root Length of Raphanussativus (radish). This proved that allelopathy is part of the relationship between crop and weed.
