Effects of training systems on the growth and fruiting of 'Fuji'/M.9 apple trees on a newly planted site in Korea
A field experiment was established in Hwaseong, Korea in 2009 where 'Fuji' apple trees on M.9 rootstock were planted and trained to the following systems: Narita, slender spindle, and Solaxe. We compared tree growth and fruiting through the fifth leaf in 2013. Narita resulted in the tallest trees while slender spindle had the largest tree width, trunk diameter and TCA. The slender spindle had lower fruit number tree-1, fruit weight TCA-1 and fruit weight per ha compared with Narita or Solaxe. The flower bud number over 4.5 mm in diameter tree-1 counted after pruning in mid-March in 2014, showed significantly larger number with Solaxe compared with Narita or slender spindle.
