Abstract
The objective of the current study is to investigate the allelopathic
potential of invasive weed Senna uniflora with its leachates on rice
varieties Ambemohor and Jeera Kolam that are commonly cultivated in Maval
region of Pune district (MS). A petriplate bioassay investigation showed that
greater concentration of aqueous leachates (20%) significantly reduced seed
germination as compared to lower concentrations (4%, 8%, 12%, 16% and control).
Phytochemical analysis by GC-MS technique revealed presence of many
phytochemicals in Senna uniflora leachates. Compared to root and stem
leachates, the 20% concentration of leaf leachate had a greater toxic effect on
seed germination parameters. This is probably because of leaves containing more
allelochemicals than root and stem. Jeera Kolam was observed more resistant
than Ambemohor to the allelopathic effect of Senna uniflora. The results
of this study could be useful in planning some measures for utilization of this
weed in sustainable agriculture.
