Abstract:

In order to study the effect of salicylic (SA) acid on the strawberry (Fragaria × ananassa Duch cv. Camarosa) plants, a two-factorial field experiment was carried out according to completely randomized design with three replications in 2011 and 2012. The factors included different concentrations of SA (0, 0.5 and 1 mM) and number of SA application (1, 2 and 3 times). Chlorophylls content and fresh and dry weights of leaf and root were performed at the harvest time. The results showed that chlorophyll a, chlorophyll b and total chlorophyll content significantly increased with increasing the SA concentration and the number of SA application as the highest amount was found in 1% SA and thrice sprays. The numbers of SA application significantly enhanced leaf fresh and dry weights, whereas different SA concentration had no significantly effect. Moreover, root fresh and dry weights had not significantly affected by SA sprays. Overall, the results suggested that thrice spays of SA in 1 mM concentration, which showed the better growth characters, could be more appropriate to use in strawberry spraying programs.
