Effect of Foliar Application with Some Micronutrients, Ascorbic Acid and Vitamin B complex on Leaf Nutrients Content, Fruiting and Fruit Quality of Anna Apple Trees
Department of Fruit Research, National Research Center, Dokki, Giza, Egypt
Abstract
Anna apple trees of 15 years old budded onto MM 106 rootstock grown in clay soil, were sprayed during
2005 and 2006 seasons with Zn, Mn and Fe sulfate at 1.0% as well as Boric acid at 400 ppm, Ascorbic
acid at 1000 ppm and Vitamin B complex at 100 ppm. The trees received three sprays in March, April
and May. Leaf nutrient contents, fruiting and fruit quality parameters were recorded. Spraying with
FeSO4, Boric acid and Vitamin B complex increased leaf N and P. Also, all treatments under study
increased leaf Fe, Zn and Mn content while all tested treatments produced a considerable increase in fruit
set, yield number of fruits and fruit weight and decrease in fruit drop parameters. Generally, Boric acid,
Ascorbic acid and Vitamin B complex treatments were superior than the other treatments and control.
Meanwhile, spraying the trees with Ascorbic acid or Vitamin B complex was more effective in increasing
TSS, acidity, total sugar and starch as compared with the other used treatments and the control.
