SIMPLE BIO ASSAY METHODS FOR RICE ALLOELOPATHY

摘要

This research was conducted for evaluating a simple bioassay method for rice allelopathy. Water extract, relay seeding and agar medium method were tested to obtain reliable data applicable to different conditions for screening rice allelopathic potential. Relay seeding method was simple and easy to carry out, but it had some problems in discriminating a specific allelopathic line because all tested cultivars exerted to some extent allelopathic effects. Agar medium test was not simply easy to handle.Water extraction from seeds gave relatively reliable information, and thus, water extraction directly from seeds seemed to be a simple and reliable method for evaluating rice allelopathic potential.
