Effect of Chenopodium album root, shoot, leaf and bud aqueous extracts on physical and biochemical parameters of wheat seedlings

Allelopathy is the type of interaction where two organisms interact with each other in positive or negative manner and are secondary metabolites mediated. Varieties of crops and weeds have been reported to possess allelopathic effect on growth of other plant species. To replace the harsh effect of the fertilizers in the agricultural field, use of the biostimulants is rapidly being used. Plantbiostimulants are substances and materials which can modify physiological processes of plants in a way that they help in growth, development and/or stress tolerance response. So, allelochemicals when applied to the low concentration can have stimulatory effect on growth and development of plants. Therefore, various aqueous extracts of Chenopodium album plant part are used to investigate its role as stimulatory or inhibitory effect on wheat crop seeds. Aqueous extracts of Chenopodium album at six different concentrations (10 mg/mL, 25 mg/mL, 50 mg/mL and 100 mg/mL, 15 mg/mL and 200 mg/mL along with Control) of leaf, shoot, root and buds of Chenopodium album were tested on wheat seedling. Leaf shoot, root and bud extract showed best morphological result in varied concentration i.e. 50 mg/mL, 50 mg/mL, 25 mg/mL and 100 mg/mL in all the parameters i.e. shoot length, root length, wet weight and dry weight of root and shoot respectively. Different biochemical parameters were measured like chlorophyll estimation, proline, total dissolve sugar and protein content in selected concentration of extract. Among all the extracts, shoot extract showed the best quality of seeds when biochemical parameters were measured. Results of our study suggest that the effect of weeds was beneficial on wheat crops at lower concentration of extract.
