Abstract:
Aqueous extracts of freshly collected shoots (10% concentration) of the herbaceous forage species (grasses: Axonopus compressus and Chrysopogon aciculatus, legumes: Alysicarpus vaginalis and Desmodium triflorum) occurring round the year in grazed land at Biratnagar significantly inhibited root length of paddy seedlings in the order D. triflorum (40.0%) > A. compressus (36.7%) > C. aciculatus (34.5%) > A vaginalis (32.5%). At similar concentration, significant reduction in shoot length of paddy seedlings was caused by shoot extracts of C. aciculatus (27.3%) and D. triflorum (28.6%). In comparison to rhizome and root extracts of other species only rhizome extract of A. compressus had significant inhibitory effect on root length (33.3%) of paddy seedlings. Phytochemical screening revealed the presence of volatile oils, fatty acids, sterols, triterpenes, anthocynins, polyoses and tannins in grass and legume species studied: whereas alkaloids, coumarins and saponins were exclusively present in legume samples.
