Two strawberry cultivars (Camarosa and Maraline) grown in soilless culture were inoculated with two arbuscular mycorrhizal fungi (Glomus clarum and Glomus caledonium) and three phosphor doses (10, 30 and 60 ppm). The effects of arbuscular mycorrhiza on the vegetative and reproductive characteristics of strawberries were evaluated. Total yield, fruit size, runner number, dry weight of leaves, fruit characteristics such as pH, acidity and total soluble solids were also determined. The results show that mycorrhizal inoculation statistically increased the yield in Maraline cultivar and had no significant effect on other vegetative characteristics. On the other hand, both phosphor and mycorrhizal inoculations resulted in significant decrease on total soluble solids and pH in the fruits of both cultivars. Our limited study shows that mycorrhizal inoculation of the strawberry plants may cause minor biotic stress on the strawberry plant.
Key words: Mycorrhizae, strawberry, phosphor, soilless.
