TY - JOUR AU - Kosina, Romuald AU - Grabińska, Anna PY - 2016 TI - Variation of starch granules in diploid species of the genus Avena L. JF - Modern Phytomorphology; Vol 10 No Suppl. (2016) DO - 10.5281/zenodo.159036 KW - N2 - Composite starch granules, the main product of assimilation in oat endosperm, were analyzed in the accessions of both wild and cultivated diploid species of the genus Avena . Simple starch granules are mostly synthesized in the outer parts of the endosperm tissue. The size of sub-grains in a composite granule does not depend on a wild or cultivated status of the species. Inter-specific variation in the size differences of composite granules is large. Also, a broad variation has been detected for granules analyzed in a Lugol’s solution or polarizing light. This analysis revealed a difference between the synthesis of amylopectin versus amylose in a granule. Examples of occurrences of low levels of amylopectin synthesis are provided.
