AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    In the rain season of 1982-1983 (November-January), it was studied the dynamics of accumulation of reserve substances and total glycoalkaloids in growing tubers of the Brazilian potato cultivars Aracy (IAC-2), Itaiquara (IAC-355 1) and Teberê (IAC-4489). Data are related to three sampling dates, 64, 79 and 111 days after planting (DAP).
