Effect of EC Irrigation Water on Morphophysiological and Elements content of Rosa cv. Dolce Vita in Hydroponic Culture

This study for Effect of EC Irrigation Water on Quality and Quantity of Rosa cv. Dolce Vita in Hydroponic Culture, in a completely randomized design experiment with 4 treatments, 3 replication, were conducted. Pot without irrigation with sodium chloride was used as control. To perform the experiment, cuttings of roses were prepared and cultured in 5-kg pots containing 70% cocopeat and 30% perlite. Irrigation was carried out twice a day at the beginning of the experiment with saline water and after the third day irrigation was done by applying salinity treatments in all treatments equally (with equal volume ratio). Quantitative and qualitative traits of plant such as fresh and dry weight of shoot, flower number, bud diameter, stem diameter, petal length, anthocyanin of petals, total chlorophyll of leaf, potassium and calcium content and longevity of rose on plant were evaluated. The results showed that application of all salinity levels due to sodium chloride salt reduced all evaluated traits compared to control. Also, analysis of variance table showed that the effect of treatment on all traits was statistically significant at 1% level and there was a positive and significant correlation between all traits at 1 and 5% level
