摘要：

The aim of this work was to determine whether genotype and growing conditions influence the composition and physical properties of potato tuber starch granules. Starch is thought to be the source of the reducing sugars produced during low-temperature sweetening. Genotype influenced the properties of starch granules but there was no consistent difference between sweetening and non-sweetening cultivars in the properties of their starch granules. Growing conditions affected starch granule characteristics with starch from tubers grown in the heated glasshouse conditions having higher gelatinization temperatures and amylose contents as well as greater resistance to degradation by bacterial alpha-amylase.
