Assessment of some chemical and qualitative characteristics of Marigold as influenced by different culture media

In order to evaluate the effect of different culture media on chemical and quantitative characteristics of Marigold, an experiment was conducted in completely randomized design with eight treatments and three replications in Islamic Azad University of Isfahan (Khorasgan) branch during the year of 2014. The treatments were including garden soil, garden soil spent mushroom compost, garden soil spent mushroom compost rice bran, garden soil spent mushroom compost rice bran manure, garden soil rice bran, garden soil rice bran manure, garden soil spent mushroom compost manure, garden soil manure. The results showed that increasing manure in various treatments enhanced carotenoids and anthocyanin in Marigold, so that the highest carotenoids and anthocyanin was observed in the combined treatment of manure, but adding rice bran and garden soil alone reduced carotenoids and anthocyanin in Marigold. The effect of the combined media (garden soil spent mushroom compost rice bran manure) increased content of leaf flaveonoids, but absent of manure and mushroom compost significantly decreased them. The chemical compositions of Marigold were Delta-Cadinene, Gamma-Cadinene and Phthalic acid. The highest Delta-Cadinene obtained from spent mushroom compost garden soil manure medium.
