A Study on the Allelopathic Impact of Chenopodium murale L. on Wheat Crop Plants

Abstract

Allelopathy is a mutual biological occurrence in which the growth, development, and reproduction of other organisms are impacted by the biochemicals produced by one organism. Allelochemicals are a class of biochemicals that can either benefit or harm the target species. Plant allelopathy is one of the ways that receptor and donor plants interact, and it can have either beneficial or negative effects. Organic soluble plant extracts have an inhibitory impact. A dose–response relationship analysis is required in bioassay laboratory tests, since the stronger inhibitory impact of higher concentration extracts may be attributed not only to allelopathy but also to enhanced osmotic potential. The negative effect on seedling growth is often larger in bioassays than the influence on germination rate. To study the effect of Chenopodium on wheat crop was studied by applying leaf extract of Chenopodium murale on wheat plant. The weed samples of C. murale were collected from fields and road sides of the University. The different concentration of Chenopodium extract (i.e. 50%, 75%, 100%) were appliedon wheat plants. The results after three days were compared with the control. The result shows that Chenopodium has less inhibitory effect at lower concentration and strong inhibitory effect at higher concentration
