The effect of salicylic acid foliar spraying on qualitative characters of strawberry fruit (Fragaria x ananassa cv. Camarosa)

Document Type : Full Paper



In order to evaluate the effect of foliar application of salicylic acid on the qualitative characters of strawberry fruit, a factorial experiment (treatment+ the time of harvesting) based on completely randomized design with 3 replications was conducted in a greenhouse and the laboratories of Department of Horticultural Science of University college of Agriculture and Natural Resources, university of Tehran, located in Karaj, during 2010-2011. The experimental plantlets were planted in 3030 pots and filled with coco peat and perlite in the rate of 1:1 and Salicylic acid at 4 levels (0, 1, 2 and 4 mM) was sprayed on strawberry leaves every month regularly. After ripening, fruits were divided into 4 groups. The first group was transferred to the laboratory with one week away after treatment and ripening, the second group was transferred to the laboratory with two week away after treatment and ripening and so the third and fourth groups, were being taken to the laboratory after tree and four week away of receiving treatment, respectively. The strawberry plants were evaluated on qualitative factors such as: fruit weight, fruit humidity percentage, Total Soluble Contents (TSS), ...
