Effect of different Substrates and Varieties on Yield and Quality of Strawberry in Soilless Culture

摘要

Most growing media for strawberries in soilless culture are peat moss, rockwool, coir, perlite or some othermixtures. Nowadays, using mixture of peat moss and perlite is one of the mostly used substrate for productionof hydroponic strawberries in developing countries. The effects of three different media based on 100%: 0,80%: 20% and 60%: 40% v/v perlite and peat moss were evaluated on quantity and quality of three varietiesof strawberry (Fragaria ananassa) in soilless culture. Perlite/ peat moss substrate 100%:0% ratio (v/v) producedthe most number of leaves and flowers number and the number of fruits and fruit dry weight were the highestin both substrates of 100%:0 and 60%:40% perlite/peat moss. Fresno variety had the highest number of leavesproduction between three studied varietie., However, both Fresno and Selva had the highest number of fruitsand fruit dry weight and the difference between these two varieties were not significant. All in all, the resultsshowed that based on the goals of planting strawberries, both Fresno and Selva varieties and also 100%:0 and60%:40% perlite/peat moss are the best ones in production of strawberries in Iran.
