Sugars in Iris pseudoacorus L. seeds

Abstract

Qualitative and rough quantitative analyses of sugars occuring during the successive developmental phases in two poles - micropylar and chalasal - of the seeds of Iris pseudoacorus L. were made. Comparing the sugar dynamics of the respective developmental phases distinct differences were found in mature and immature seeds. Soluble polysaccharides being an initial form of accumulation do not occur in ripe seeds. No differences were found in the contents of insoluble sugars in chalasal and micropylar poles. The endoperm and the seed coat differ in the level of some sugars.
