Title: Fruit Quality from Micropropagated Apple (Malus domestica Borkh.) Trees vs. Fruit from Trees on Seedling and M 7a Rootstocks
Authors: S.R. Drake, F.E. Larsen and S.S. Higgins
Abstract:
'Golden Delicious' and 'Spartan' apples from
micropropagated trees and scions on seedling
and M.7A rootstocks were evaluated for three
seasons, at harvest, and after 120 days of storage
(1°C) for quality.
Ethylene production indicated
that apples from the three rootstocks matured
at approximately the same rate and could be
harvested in the same time period.
Apple quality
was similar among the three types of rootstocks,
and no particular quality advantage was apparent for firmness, soluble solids concentration,
titratable acidity, carbohydrates or mineral content.
Fruit from micropropagated 'Golden Delicious' trees were more yellow at harvest than
fruit from other rootstocks, but this difference
did not exist after storage.
