Abstract: 

A new approach to improve the quantity and quality of agricultural products is the use of plant growth regulators. Brassinosteroids as plant growth regulators in low concentrations affect yield and quality of agricultural crops. To evaluate the effect of 24- Brassinosteroids on quantitative and qualitative factors in strawberry fruit (Fragaria ananassa cv. Sabrosa) an experiment with 24- Epibrassinolide (0, 1 and 4 mmol/lit) based on completely randomized design with four replications, was conducted in a hydroponic medium in greenhouse conditions. The highest level of yield and characteristics was resulted in 4 mmol/lit of 24- Epibrassinolide. 1 mmol/lit 24- Epibrassinolide significantly increased starch content and total acidity of strawberry fruit, while the highest increase in the sugar and soluble solids content was resulted in 4 mmol/lit of 24- Epibrassinolide. The results show that the use of 24- Epibrassinolide is effective to increase the quantity and to improve the quality of strawberry fruit.
