Mean value of two measurements; values within a column sharing a common letter are not significantly different (p < 0.05).
YKG; Yukon Gold, VIC; Victoria, INN; Innovator, SET; Setina, SIG; Sierra Gold.
Defined as the percent ratio of each fraction area to the total area of the chromatogram.
F1; DP_n>72, F2; DPn 25-72, F3; DP_n<25.
Defined as the percent ratio (%) of the total area of the crystalline regions to that of total diffractogram (crystalline + amorphous regions).
Determined at 80oC using a blue dextran exclusion method (Tester and Morrison, 1990).
