Application of Non-Traditional Minerals in the Media and Their Impact on Some Quantitative and Qualitative Traits of Polianthes tuberosa L

One of the most important cut flower in the tropical and subtropical areas of world and Iran, is Polianthes tuberosa, which is well-known and popular for its pleasant fragrance and many floral aesthetic features. In this research, the effect of substrate on length, fresh and dry weight of stem, length of floret, daughter bulblet circumference, fresh and dry weight of root and leaves was evaluated in complete random design with 3 replications and 13 treatments that was performed during the 2015-2016, in Isfahan. The soil that received from polianthes producer in Dezful was control treatment. Minerals such as feldspar, talc, dolomite and tuff with amounts of 10, 20 and 40% are added to substrates with 20% manure and balanced by garden clay soil. Results of ANOVA of data showed that in substrate with 40% talc, length, fresh and dry weight of stem and chlorophyll content, in substrate with 10% tuff the length of floret, increased significantly. Also in substrate with 20% dolomite, fresh and dry weight of root and in substrate with 40% feldspar, daughter bulblet circumference, increased significantly. Based on the results of this study, application of talc %40, dolomite %20, feldspar %40 and tuff%10 were effective on improving growth properties of Polianthes tuberosa.
