Allelopathic effect of kukronda (Blumea lacera L.) on linseed Oudhia P., Tripathi R.S. Department of Agronomy, Indira Gandhi Agricultural University, Raipur-492001, India Abstract A1lelopathic effects of Blumea Lacera L. on linseed were investigated. Root, stem, leaf and stem+leaf of Blumea lacera L. were allowed to decay for 120, 168; 216 and 264 hrs in normal water in the ratio of 1:10 w/v of plant material and water respectively. Linseed variety Kiran was used as test crop. Different extracts of Blumea produced significant effects on germination and seedling vigour of linseed. At 5,7,9 and 11 DAS, stem extract of 120 hr. produced maximum germination and 11 DAS, leaf extract of 168 hr suppressed the germination of linseed. Positive (inhibitory) allelopathic effect of different part and decaying periods was noted in case of shoot length. Leaf extract of 264 hr promoted the root elongation. Stem extract and root extract of 120 hr resulted in maximum shoot and root weight, respectively. Top | |
