Factor analysis solutions differed among cultivars in details
(numbers of factors and loading values), but were similar in patterns. Factor 1 accounted for a much greater portion of the
variance than did succeeding factors in all cultivars (Table 4).
Based on the variables with high loadings on factor 1, factor 1
seems to represent the general underlying structural strength of
the tissue. All instrument variables in which compression force
was an element (acronyms beginning with F, W, or M) had high
loadings on factor 1. CRISP, HARD, and TOUGH related strongly
to factor 1 and MEALY and SPONGY had relatively high loadings
on factor 1. JUICY also generally related to factor 1; juiciness
would relate to turgor pressure and turgor should account
for a part of the overall structural strength of apple tissue
