Abstract

This study aimed to evaluate the efficacy of some aqueous plant extracts of thyme leaves and cinnamon bark on germination and growth of yellow Corn seedlings and their associated fungi. The results showed that the highest moisture content of yellow corn kernels was at sample place 7 and the lowest at sample place 1. The results of isolating fungi associated with yellow corn kernels after adding extracts in the tested samples showed the presence of the following genera and fungal species in small numbers compared to isolating fungi accompanying yellow corn kernels before adding the extracts: Asperigllius niger, A. flavus, A. nidulans,, Fusarium moniliforame, as indicated. The results of the percentage of germination of yellow corn before adding the treatments were that the highest percentage of germination was for a sample of substitute (4) and the lowest for a sample of (3). The treatment with two concentrations 75 and 100% of the thyme and cinnamon extracts resulted in an increase in the percentage of germination ranging between 80-100% in the tested samples. This was accompanied by an increase in the length of the spheres and radicals in most of the studied samples.
