COMPARATIVE ALLELOPATHIC EFFECT OF SYZYGIUM AROMATICUM AND MYRISTICA FRAGRANS ON SEED GERMINATION OF AMARANTHUS CRUENTUS

Abstract

The present study aimed to compare the allelopathic effect of aqueous leaf extract of Syzygium aromaticum and Myristica fragrans on seed germination of Amaranthus cruentus. The study was conducted by petridish method using four different concentrations of aqueous leaf extracts of both plants for seven days. The control group was also maintained. The number of germinated seeds on each days of experiment were recorded and the germination percentage were calculated using the data obtained on the seventh day. The percentages of seed germination were found decreased according to the increasing concentration of leaf extracts of both plants. The aqueous leaf extract of Syzygium aromaticum showed more inhibitory effect on seed germination of Amaranthus cruentus than that of Myristica fragrans.
