Comparison of Allelopathic Potential of Sri Lankan Improved Rice Varieties (Oryza sativa L.) using Radish (Raphanus sativus L.) as an Indicator Plant
- Dr. D. L. Wathugala; Ms. A. S. Ranagalage
- Allelopathy is a sound alternative strategy to deal with weed management in paddy ecosystem in sustainable manner. Allelopathic influence imposes from chemicals which secrete from plants and called as allelochemicals. To avoid the hazardous and indiscriminate use of chemicals for weed control in paddy fields much concerns were deposited on proper assessment and manipulation of allelopathic properties of rice plants. There is a huge variation in allelopathic potential among rice varieties. Therefore, in this experiment relay seeding technique without soil (experiment 1) and soil as a medium (experiment 2) were conducted under laboratory condition to observe and screen the allelopathic potential of selected Sri Lankan improved rice varieties on seed germination, shoot and root length and dry matter production of radish (Raphanus sativus) as a phototoxic sensitive test crop. Most of the tested varieties of rice were performed inhibitions to studied characters of radish. In contrast some varieties act as stimulant rather than inhibition (At 306). In both experiments, the highest dry weight reductions were noticed with Ld 365 (53.8 and 56.9% respectively), Both the evaluation methods were positively correlated in determining percent reduction in all the measured parameters of radish. According to the results it can be concluded that the allelopathic potential of rice varieties varies in a very broad range and out of varieties tested Ld 365 showed highest allelopathic potential against radish growth.
