Abstract :

Silicon is one of the useful nutrient elements for plant growth that in soil cultivations, plant requirement to this element partly will supply but it may never be enough in soilless culture. However, the aim of this study was investigate the effect of Silicon (Si) on the qualitative and quantitative of two strawberry cultivars in soilless culture. This experiment was conducted as a factorial based on randomized completely blocks design with three replications and three plants in each replication. The medium cultures that were include perlite and cocopeat (1:1) and an experiment was conducted in a greenhouse that located in the city of Yasouj. Spray of Si in four concentration (0, 200, 400 and 600 mgl-1 from Silisilic Acid source) and cultivars (Paros and Aromas), were investigated factors in this study. Characteristics such as number of leaf, fruit weight, number of fruit per plant, yield of single plant, chlorophyll index and vitamin C were measured. Results showed that effects of Si and cultivar on the yield of single plant, fruit weight, number of leaf and chlorophyll index were significant. The highest yield of single plant was obtained in Paros cultivar with 1218 gr as compare to Aroms cultivar. Plant treated with Si 400 mg/l showed the highest yield to compare with control. So, application of 400 mg/l Si on Paros cultivar was recommended in soilless culture.
