This study was conducted during 2015 and 2016 seasons to examine the effect of nano versus normal boron on yield and quality of the berries of Flame seedless grapevines grown under Minia region conditions.
Treating Flame seedless grapevines three times by nano boron at 0.0125 to 0.05 % or by normal boron at 0.025 to 0.1% considerably improved berry setting %, yield per vine, cluster weight as well as physical and chemical characteristics of the berries relative to the control. Using boron prepared by nanotechnology was superior than using it through normal methods in this respect. The best results in regard to yield and berries quality of flame seedless grapevines were obtained by treating the vines three times by nano boron at 0.025%.
