Allelopathic Potential of Convolvulus arvensis Linn. on seed germination and seedling growth of Wheat (Triticum vulgare)

Convolvulus arvensis Linn. is a member of family Convolvulaceae. In the previous studies the allelopathy, leachtes of C. arvensis have been prepared from root, stem and leaf and their chemical changes have been also recorded. Further studies have been carried out to observe the effect of these leachates on seed germination and seedling growth of wheat crop plant. It was observed that there is change in pH value of stem, leaf and root leachtes from first day to six day and different dilutions. The pH value of water is significantly affected by allelochemicals of root during the continuous flow of water and this crop present field to be effected by the water of consisting changed pH value. The effect of these weed on the seed germination and seedling growth of wheat crop have been studied and it was found that leachates treatment inhibits the seed germination and seedling growth of crop plant. In the allelopathic study we can show that the stem extract of C. arvensis Linn. is more effective that of root and leaf extracts.
