Effect of different culture media on physicochemical characteristics, growth and flowering in Chrysanthemum

In this study, Effect of different culture media on physicochemical characteristics, growth and flowering in Chrysanthemum, in completely randomized experimental design with 7 treatments, 3 replication and each treatment with 3 cutting, a total 63 cutting were conducted. Treatments includ cocopit, perlite, sand and in combination with each other. About three months after planting of cuttings, flower buds formed and sampled and evaluated the desired traits. Physicochemical and enzymatic traits of the plant such as air and root fresh weight, air and root dry weight, plant length, number of flower, anthocyanine of petals, total chlorophyll of leaves, proline, protein, superoxide dismutase activity and flower life on plant were evaluated. The results showed that Coco+Sand+Per treatment had the most effect on the improvement of traits such as f air and root fresh weight, air and root dry weight, plant length, proline, flower life on plant and Per+Coco treatment also had the most effect on the improvement of traits such as number of flower, anthocyanine of petals, total chlorophyll of leaves and superoxide dismutase activity. Coco+Sand+Per treatment with 8.2 days was highest and Sand treatment with 4.8 days had the least flower life on plant. Also the correlation between traits showed proline with air and root fresh weight, air and root dry weight, number of flower, protein, superoxide dismutase activity and flower life on plant, had a negaitive and significant at 1% level and with anthocyanine of petals and total chlorophyll of leaves, had a negaitive and significant at 5% level. Number of flower with plant length, anthocyanine of petals and total chlorophyll of leaves, had a positive and significant at 5% level and other traits had a positive and significant at 1% level.
