The Effect of Different Concentrations of the Thinner Globaryll100 on Chemical Characteristics of Gala Apples

Abstract

Apple (Malusdomestica) is a plant in the form of short shrub or tree with branches lacking thorns and simple oval obular leaves and small and short head. Apple buds include vegetative or simple buds producing branches and its fertile buds are plain mixed generative buds and produce five flowers and 7-8 leaves when waking up. Apple is of great importance in the world so that in 2011, 75.5 million tons of apples were produced and consumed in the world according to the FAO. It has a lot of properties such as maintaining healthy skin, preventing cancer, and so on. The thinner Globaryll100 at concentrations of 150, 250 and 350 mg were used in the Gala apple varieties with the aim of resolving the problem of alternate fruiting and making coarse and high quality fruits and then traits such as pH, acidity, dry matter content, sugar content, total soluble solids were measured. Globaryll was used when the fruit was 10 mm. Globaryll at a concentration of 350 mg per liter has achieved the first place of Duncan in terms of sugar content, soluble solids, pH, and percentage of dry matter. The results showed that the effect of treatments on all traits was significant except acidity, and also high concentration of both hormones could reduce fruiting percentage compared to the control.
