The Washington Tree Fruit Research Commission (WTFRC) Internal Program has developed a starch index for Honeycrisp (scale 1-6) based on actual starch patterns observed for fruit grown in Washington State. A modified logistic model was proposed to represent the sigmoidal starch index pattern during the preharvest period by two model parameters. New Zealand Journal of Agricultural Research: Vol. Wood Engraving. Starch Index Determination of Apple Fruit by Means of a Hyperspectral near Infrared Reflectance Imaging System Show all authors. The expression pattern of neither MdSUSY1 nor MdSUSY4 is consistent with decreased SUSY activities during apple fruit development (Figures 3, 5).

New Zealand Journal of Agricultural Research: Vol. In the starch test, iodine binds with starch granules in the fruit and develops into a dark purple to almost black color. Additional indexes. In contrast, the expression patterns of MdSUSY2, MdSUSY3 and MdSUSY5 showed general agreement with decreased SUSY activities during fruit development (Figures 3, 5). With this technique, the orchard and cultivar effects were analysed. The pattern of starch disappearance is specific for each apple variety. For example, Delicious loses its starch in a fairly even ring, while Golden Delicious shows an uneven pattern. Starch hydrolysis continues during apple ripening on-tree and off-tree in storage, however, the speed of starch degradation in fruit on-tree and off-tree held at different temperatures is not known. The starch reacts with the iodine solution to produce a blue-black colour in a pattern characteristic for that cultivar. The harvest time of apples, matching the desired commercial characteristics, is assessed through starch–iodine test in practice. News. Shop. Kate's Silk Screen . Starch Pattern Index (SPI), a measure of starch hydrolysis, where the amount of starch iodine staining and stain pattern through the equatorial half of an apple is scored as an index.
