Germplasm is a source of genetic variability available for plant breeding. These techniques have becomeaccessible and necessary to protect biological diversity. The collections are groups of representative geno-types with the genetic variability of the species that is the object of conservation. Four samples of pinhão,obtained from Paraná pine seeds, were supplied by EMBRAPA Florestas (germplasm bank). Starch wascarefully extracted in aqueous solution, whose yield was around 32.5%. For each sample the gelatinisationtemperature (Tp) occurred below 63.6?C and gelatinisation enthalpy (Hgel) was different for each sam-ple. TG?DTA curves showed similarity, although with mass losses and peaks at different temperatures.The pasting temperature obtained by RVA was directly proportional to the onset and peak temperaturesobtained by DSC. The XRD technique allowed the degree of relative crystallinity to be calculated for eachsample. From the results it can be verified that each sample had specific characteristics. |
