All trees were raised as slender spindles, and planted in north-
south direction and in twin-rows in Granny Smith and Fyriki (4 m
distance between double rows, 1 m distance inside the twin-rows,
and 2 m distance on the rows), and single rows in Fuji Kiku 8 and
Imperial D.R.D. (4 m × 1 m). Granny Smith and Fyriki were 10 year-
old, and Fuji Kiku 8 and Imperial D.R.D. were 8 year-old. Granny
Smith was grafted on M26 rootstock, and the rest of cultivars were
grafted on M9 rootstock. All trees received routine horticultural
care.
