Abstract

Effect of the foliar boron (B) application on nutrient uptake and fruit quality of tart cherry (Prunus cerasus L.) was investigated from 2008 to 2009 on mature four favourite Hungarian tart cherry cultivars like ‘Oblacsinszka’, ‘Érdi bôtermő’, ‘Újfehértói fürtös’ and ‘Petri’. Tart cherry trees grown in Eastern Hungary (Újfehértó) on an acidic sandy soil with low B content. Trees were treated with B by foliar application (0.5% B) at full bloom and untreated with B served as a control. B sprays strongly affected on B content of inflorescences. However, B sprays had no consistent effect on summer leaf B status. In our experiment stronger year effect was observed at leaf B status than flower B status. The effectiveness of early spring boron applications are limited and mostly affected the flower B status only. Moreover, treatments had inconsistent effect on studied fruit inner parameters. Monosaccharides, vitamin C and organic acid contents of sour cherry were stronger affected by cultivars than applied treatments.

Highlights

Boron (B) is an essential micronutrient in plants and among micronutrients its role is studied more frequently than others all over the world due to its advances on the fruit set and maturity (Faust, 1989; Fallahi et al, 2010)

Summary

Introduction

Boron (B) is an essential micronutrient in plants and among micronutrients its role is studied more frequently than others all over the world due to its advances on the fruit set and maturity (Faust, 1989; Fallahi et al, 2010). Despite of the intensive research, the role of B in plant is still least well understood of all mineral nutrients (Mengel et al, 2001). B deficiency occurs often because most of the boron in the soil is adsorbed to clay minerals, hydrous metal oxides, and organic matter in soils. Boron can be co-precipitated with calcium carbonate making it unavailable to the roots. Boron deficiency is occurred mostly at heavily clayed soils and sandy soils with low status of organic matter as well
