Abstract
The paper presents the results of a study regarding the influence of aqueous extracts obtained from Levisticum officinale and Apium graveolens leaves on seeds germination and seedlings growth in Raphanus sativus and Lens culinaris species. The following parameters have been determined: the pH value of aqueous extracts; the germination percentage between 24 - 96 hours, and the average length of the root. The results of the investigations that were carried out reveal the following aspects: the aqueous extracts from leaves have a low acidic - neutral pH; the germination percentage and the average length of the seedlings root (at seven days after the experiment’s setting up) present specific value variations according to the extract’s concentration, the type of extract and the test species that was used. It was noticed a delay of the growth in length of the root at both species.
