Rice allelopathy and its physiobiochemical characteristics

Abstract

Abstract: Selecting six strong allelopathy rice varieties as donor plants,barnyardgrass as receiver plant,authors dealt with the allelopathy and physiobiochemical characteristics of rice.The results show that increasing the extract concentration enhanced the inhibition effect on the growth of barnyardgrass.The inhibition effect was negatively correlative with the target weed densities.The aqueous extracts of rice leaves significantly inhibited the activities of superoxide dismutase and catalase in barnyardgrass,therefore affected the growth of barnyardgrass.The activity of PAL was positively correlative with the content of phenolics.The interaction of phenolic compounds might be additive or antagonized.
