Title: Influence of Rootstock on Fruit and Tree Characteristics of 'Macspur Mclntosh'
Authors: M. Meheriuk, H.A. Quamme and R.T. Brownlee
Abstract:
Macspur Mclntosh apples grown on 4 rootstocks
(M.9 EMLA, Ottawa 3, M.26 and M.4)
were harvested at weekly intervals over a 5-6
week period and assessed for internal ethylene
content (IEC), red skin colour, average fruit
weight, flesh firmness, starch index (SI), soluble
solids concentration (SSC), and titratable acidity.
Data from the 4-year study showed no significant effect of rootstock on the proportion of
fruit with an IEC of 1 ppm or more, a level
indicative of fruit in the climacteric stage.
Red
skin colour, firmness, SSC, SI, and average fruit
weight showed some differences in 1 or 2 years
of the study but no trends were evident.
Cumulative yield was not significantly different with
rootstock but tree canopies on M.9 EMLA and
Ottawa 3 were smaller and more yield efficient
than canopies on M.26 or M.4.
