Effects of environmental factors on composition, structure, and physicochemical properties of native starches from different plants have been extensively studied. Among parameters to which attention was paid were environmental factors there is a growth (soil) temperature during plants development (growth temperature) that plays one of the most important role. The application of different physical approaches for a description of the thermodynamic melting parameters of starches allows to determine the cooperative melting unit, the thickness of crystalline lamellae and to evaluate the role of defects in the structural organization of native granules at changes of growth temperature. As example it is considered the influence of growth temperature of plants on the properties of normal potato and sweet potato starches as well as waxy, normal and high-amylose barley starches, i.e. starches with different polymorphous structures of B-, C- and A- types, correspondingly. The nature of calorimetric peaks doubled for some normal and high-amylose barley starches at a decrease in growth temperature is discussed.
