Allelopathic Effect of Bindweed (Convolvulus arvensis L.) on the Germination and Growth of Zea mays L.

Abstract

Convolvulus arvensis L., has both competitive and invasive properties that can directly or indirectly damage the other plants by production of carbon-based chemicals known as allelochemicals. The goal of the current investigation is to find the allelopathic capability of Convolvulus arvensis L. against Zea mays L. Leaves of Convolvulus arvensis L., 5g, 10g, 15g of both fresh and dry are immersed in distilled water (100 ml) for 24, 48, and 72 hours. For examination of growth factors such as radicle and plumule length, germination potential, and germination percentage. Zea mays seeds are taken and consequently treated with the extract of Convolvulus arvensis. The findings showed that the germination potential and germination percentage are affected more by dry leaves and fresh leaves extract respectively at 48hrs soaking duration and both showed 64% comparable to control. The length of the radicle is affected more by soaking duration of 48hrs dry leaves extract of C. arvensis L., and the highest decrease recorded is 188.37%. The plumule length is affected more by a soaking duration of 48 hours dry leaves extract of C. arvensis L., and the maximum reduction recorded is 231.8%. The fresh weight of seedlings is impacted more by 48hrs soaking duration of fresh leaves extract of C. arvensis L., and the maximum decrease recorded is 47.6%. The dry weight of seedling is affected more by 72hrs the soaking duration of fresh leaves extract of C. arvensis L., and the maximum decrease recorded is 100.93%. The findings indicate that Convolvulus arvensis L., both fresh and dry leaf extract, strongly impacted Zea mays growth and germination percentage which may indicate that allelochemicals are present in the plants.
