The aim of present study was to investigate effects of
different irrigation intervals and fertilizers on total
lipid, fatty acid and sugar accumulation of Braeburn apple
cultivar under Mediterranean climatic conditions. Irrigation
program was performed for two consecutive years with three
different intervals (1, 3 and 7 days). In fertilization, 40
g N, 32 g P2O5 and 80 g K2O
per tree (with four replications) applied in the same doses
for both years, except for the increased N (50 g per tree)
for second year, considering the vegetative growth of the
trees. The fruits were commercially harvested in 2006
season. The lipid content ranged from 0.22% (daily
irrigation without fertilizer) to 0.70% (irrigation in 7
days intervals with fertilizer). The highest fatty acid was
obtained from treatment 3 (irrigation in 3 days intervals
without fertilizer) (83.95%), while the treatment 6 provided
the least value with 64.08% (irrigation in 7 days intervals
with fertilizer). Although certain changes on fructose,
glucose, sucrose and total sugars content were detected, the
differences were not statistically significantly among the
treatments.
