In order to investigate the effect of two types of fast and high seaweeds on the coasts of the Persian Gulf, Bushehr as part of the culture medium, on some quantitative and qualitative traits of tomato seedlings, peppers, cucumbers and eggplant, planted in a completely randomized blocks design with four replications at the Faculty of Agriculture and Natural Resources of the University of the Persian Gulf in 20018. Experimental treatments included two species of "Sargassum angustifolium" and "Gracilaria corticata", each with four levels of 10%, 20%, 30% and 40%, and for each plant, a control with a base bed of cocopeat and perlite was considered to be equal. The studied traits include number of germination plants, seedling length, fresh and dry weight, chlorophyll index, chlorophyll a and b, potassium, phosphorus, calcium, magnesium and proline. The results showed that the effect of different algal levels on seed germination, height, fresh and dry weight of seedlings, chlorophyll index, chlorophyll content a and b, potassium, phosphorus, calcium, magnesium, sodium and proline of shoot in all studied plants at level The probability of one percent was significant, except for the number of germinated tomato seeds, which only reached a level of five percent. Tomato seeds had no germination in treatments with 40% Sargasum and Eggplant in treatments containing Sargasum 30% and 40%. Treatments containing Grasilaria algae significantly increased the traits of seedlings, fresh weight, chlorophyll content, chlorophyll a, sodium, magnesium and phosphorus in all plants, and the amount of proline in cucumber, and the content of calcium in eggplant, pepper Sweets and cucumbers. In the chlorophyll index, gracilaria 40% treatments were superior to other treatments in all herbs. Sargasum treatments in eggplant and gracelaria in potato pepper significantly increased potassium content. According to the results of this study, the application of algae grasilara as a part of the culture m
