This study was conducted in the Botany Laboratory, Department of Biology, Faculty of Science, University o ELmergib, during the year 2021-2022. A completely randomized design (CRD) was used with three replicates for each treatment of plant extracts, with the aim of studying the effect of these extracts on the germination and growth of wheat seedlings Triticum aestivum L. From these extracts, four treatments were prepared: M1: pure water (control), M2: anise extract Pimpinella anisum, M3: coriander extract Coriandrum sativum and M4: black seed extract Nigella sativa. The type of seeds used in cultivation is wheat. The results of this study showed that there were differences between the treatments used, as M2 and M3 gave the highest value in germination percentage, which reached 100%, and M2 and M3 were superior in germination speed, which reached 1.42 seeds/day, compared to M1 and M4, which reached 1.14 seeds/day for both of them. Treatment M2 gave the highest value in seedling strength, which reached 2025, followed by treatment M3, which reached 1983, compared to treatments M4 and M1, which recorded a value of 1456 and 1496, respectively. The results of the study also showed the superiority of M2, M3 and M4 in the length of the radicle and root, and the wet and dry weight of the radicle and root of the wheat seedling, compared to M1.
