Although chemical priming agents have been successfully used to improve seed germination, emergence and seedling quality in different plant species, still they are not yet useful for organic cultivation. Marigold is a multipurpose plant and rich source of lutein and gallic acid, to be explored as an organic priming agent. The purpose of this study was to identify an organic priming agent for organic growing and to develop appropriate methods by using two different species of marigold (Tagetes patula L. and T. erecta L.). Herbal tea obtained from the dried flower of marigold was used as a priming agent for eggplant (Solanum melongena L) cv. Pala seeds. Hydropriming and control seeds were compared with organic priming (T. patula and T. erecta) for germination percentage, mean germination time, germination rate, two different emergence tests, seedling height, seedling fresh and seedling dry weights. Data obtained from the application of organic priming (T. patula and T. erecta) showed a difference in both the germination (82 and 80%), and the emergence (73 and 76%) from Controls and Hydropriming. Seeds emerged in, which unprimed in 52 and 39% respectively, when primed with T. patula, emerged in 73 and 56% respectively. The mean germination time and the mean emergence time were shortened compared with Controls and Hydropriming. MET decreased in 1 cm and 2.5 cm depth sowing from 14.0 and 16.1 days than 10.3 and 11.9 days in Emergence-1 and 10.4 and 10.2 days in Emergence 2, respectively. Seedling quality characteristics were examined in the seedling height, the seedling fresh and dry weights of T. patula and T. erecta applications were also statistically significant. This is the first report which results showed that marigold species can be used as a potential organic priming agent.

Morus genus includes more than 20 species, some of which are commercially important mulberries with different fruit color and shape. Even though the trees of those species are propagated by rooting of cuttings in practice, mulberry seeds are of importance for breeding studies and rootstock seedling propagation. For that reason, this study was conducted to improve the seed performance of four mulberry species by different pre-sowing treatments including; 3% KNO3, GA3 at 500 ppm, organic priming with herbal tea brewed from marigold flowers petals and hydro priming. Results of the parameters of emergence characteristics and seedling vigor were evaluated. According to the results that varied between different species and pre-treatments, since emergence percentage and time, and seedling vigor were improved by the treatments, it was concluded that pre-sowing applications, especially GA3 and hydro priming, were beneficial in improving the seed performance of mulberry species included in the study.
