| dc.description.abstract | Allelopathy involves any direct or indirect harmful effect of one plant through release of chemical compounds on other. Allelopathic chemicals can also persist in soil, affecting both neighbouring plants as well as those planted in succession. Weeds are obnoxious, unwanted, ugly and persistent plants which are injurious for the crop, interfere with agricultural operations, increasing cost of labour and finally reducing the crop yield. Weeds utilize more nutrients and water than the crop plants. Weeds have allelopathic effect on crop and can result in complete crop failure. The present study deals with the allelopathic effect of four important weed species viz., Ageratum conyzoides L., Chenopodium album L., Cynodon dactylon (L.) Pers., and Parthenium hysterophorus L. on seed germination, seedling length and dry weight; total protein content and on protein profile in six different varieties i.e., Pant Anupama, Pant Bean-2, Contender, Arkakomal, HAFB-1 and HAFB-2 of french bean (Phaseolus vulgaris L.). The extracts of different weed species showed both positive and negative effect on different parameters (seed germination, seedling growth both in terms of length and dry weight; total protein content and protein profile) in different varieties of french bean. The maximum per cent reduction in seed germination was observed in HAFB-2 with extract of C. album, and minimum in Pant Anupama and Pant Bean-2 indicating that former one is highly susceptible variety and Pant Anupama and Pant Bean-2 were resistant. On the basis of per cent reduction in different parameters of seedlings of different varieties were classified into three categories namely resistant, susceptible and intermediate in response to different extracts of weeds, HAFB-2 was susceptible and HAFB-1 was resistant and rest of the varieties intermediate in terms of plumule length; Arkakomal was susceptible and HAFB-1 was resistant and intermediate in rest of the varieties in terms of radicle length; HAFB-1 was susceptible and HAFB-2 was resistant and intermediate in rest of the varieties in terms of plumule dry weight; Contender was susceptible and Arkakomal was resistant in terms of radicle dry weight; and Contender was susceptible and Pant Bean-2 was resistant in terms of total seedlings dry weight. Among different varieties of french bean, the extract of C. album showed maximum per cent reduction in both plumule and radicle both in terms of length and dry weight whereas the extract of C. dactylon showed positive effect. Due to the effect of allelochemicals, the total protein content increased on decreased in treated seedlings as compared to control. Among different varieties, in which the total protein content was increased was maximum in Pant Anupama (100%) and was minimum in Contender, Arkakomal and HAFB-1 (25%, each). The total number of bands present in different zones (A,B and C) were either increased or decreased or remain same when treated with different weed extracts compared to control. On the basis of above study, the variety Pant Anupama, Arkakomal, HAFB-1 and HAFB-2 were susceptible and Pant Bean-2 and Contender were resistant to different weed extracts. On the basis of presence or absence of protein bands present in both treatments with the control, similarity index is calculated and indicated that the effect of weed extract was more similar with C. album× c. dactylon (46.6%) in Pant Bean-2 and less similar in control × P. hysterophorus (18.5%) in Arkakomal. | en_US |
