Role of salicylic acid on yield improvement of ‘Elberta’ Peach (Prunus persica L. Batsch) tree

In other to study the effects of salicylic acid on reproductive characters of ‘Elberta’ Peach (Prunus persica L. Batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, Kerman, Iran. The application of three concentrations of salicylic acid 0 (control), 1and 2 mM at swollen bud stage were used. Results showed that application of salicylic acid improved reproductive characters of peach tree, so that tree treated with salicylic acid 2 mM significantly had higher flowering percentage, fruit weight and yield compared to non-treated trees. However, results indicated that application of salicylic acid significantly improved reproductive growth in peach trees.
