Abstract
The present research work was conducted to acquire the allelopathic effect of Rumex dentatus and Dalbergia sissoo in relevance to germination and growth of Brassica Campestris. Fresh and dry leaves of R. dentatus and D. sissoo (5g, 10g and 15g) were soaked for 24, 48 and 72 hours in 100ml of water and was filtered by using Whatman filter paper no. 1. The prepared extract was used against the test plant by observing its impact on the germination percentage, radicle and plumule length after 72 hours of incubation period at 26C. The results showed that the extract of D. sissoo effected the radicle length more as compared to plumule length while R. dentatus significantly effected the radicle length, plumule length and germination percentage. Moreover, the results also illustrated that for D. sissoo the inhibitory effects of fresh leaves on the test plant were more pronounced than the dry leaves extract whereas the inhibitory effects of dried leaves extract of R. dentatus on the test plant was more evident than the fresh leaves. The application of R. dentatus dry leaves extract completely suppressed the germination percentage, whereas in the case of fresh leaves minimum germination percentage was recorded 20% in 5g (24hrs soaking duration) as compared to control (95%). In the case of D. sissoo, the fresh and dry leaves extract showed a lesser effect on germination percentage while the application of fresh leaves extract was inhibitorier and showed more reduction in radicle and plumule length. The maximum reduction in the radicle length was recorded (0.12cm) and plumule length (0.05cm) as compared to control 3.98cm and 1.6cm in 24hrs soaking duration. From the results, it was concluded that fresh and dry leaves extract of D. sissoo and R. dentatus significantly reduces germination and growth of B. campestris in comparison to control. The reported inhibitory effects assumed that D. sissoo and R. dentatus had allelopathic potential which inhibited the growth and development of B. campestris.
