Abstract
We discovered an Araucaria angustifolia (Bertol.) O. Kuntze with sweet seeds, this is the first description and seems to be an isolated case. We aimed with this work to characterize this sweet seed and compare them with the typical one. We found that the sweet seeds presented 763% more reducing sugars, 466% more total sugar, and 54.8% lower starch content than typical seeds. They also presented higher humidity, lower resistance, and a pinkish endosperm. There was variability between sweet seeds, presenting different levels of high sugar and starch content, probably due to a gene expression modulation.
