Effect of garlic and camphor oils on bud fertility and yield components of flame seedless grape cultivar

الملخص EN

This study was conducted through three successive seasons 2010/2011, 2011/2012 and 2012/2013 on Flame Seedless grape 12 years old.

The grapevines were grown at the vineyard of Plant Pathology Department, Faculty of Agriculture, Assiut University.

The study was performed to examine the effects of spraying garlic and camphor oils at 1.0% and 1.5% each on bud fertility, yield (kg/vine) and berry quality.

The grapevine were trained as bilateral cordon leaving 48 buds/vine.

These natural oils were sprayed twice at full bloom and at the beginning of the veraison stage (when 20% of berries of 50% bunch/vine were softened).

The experiment was carried out as split-plot arrangement at one level of randomized complete block design with three replicates, one grapevine each.

All treatments of garlic and camphor oils induced significant improvement in bud fertility, yield (kg/vine), and berry weight (g).

The inferior taste of garlic oil, we recommend to use camphor oil at 1.0% to improve bud fertility, yield and berry quality of Flame Seedless grape cv.
