Reproductive and Seed Germination Characteristics of Woody Borreria (Diodia Ocimifolia) in a Plantation Ecosystem

Woody borreria belongs to the subfamily Rubioidene in the family Rubiacene. It is a brush weed 1 to 1.5 m high and reproduces through seeds. A survey confirmed the presence of woody borreria in every state of Malaysia except Perlis, Kelantan and Penang Island where there were no respondents. In...
