Abstract

The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in apple (Sheikh Amir Variety). The experiment was carried out on 10-year-old trees Shirvan region of Iran. In order to study the effect of boron on some characters of apple Sheikh Amir Variety fruits an experiment was conducted during 2010 and 2011 seasons cropping season in apple orchard at Shirvan region. The experimental design in this research was randomized complete block design (RCBD) with four replications. The treatment were comprised of two levels of pre-harvest foliar application of nutrients T₁ = Control (water foliar application), T₂ = Acid boric foliar application (0.51 g/tree). Obtained results in this research showed that foliar application on boron as pre-harvest had significant effect on dry weight, texture, Prix index and B concentration of apple fruits (Sheikh Amir Variety). Highest amount of all characters was obtained in T₂ (foliar application of boron) and minimum amount of these properties were recorded in control treatment.

Key words: Apple, boron, brix index, dry weight, fruit quality.
