SANTOS, Heloisa Oliveira dos et al. PHYSIOLOGICAL AND SANITARY QUALITY AND OIL CONTENT OF CASTOR BEAN SEEDS UNDER DIFFERENT STORAGE CONDITIONS?. Rev. Caatinga [online]. 2019, vol.32, n.1, pp.131-142.  Epub 09-Maio-2019. ISSN 0100-316X.  http://dx.doi.org/10.1590/1983-21252019v32n114rc.

The objective of this work was to evaluate the effects of different storage conditions on the physiological and sanitary quality and oil content of castor bean (Ricinus communis) seeds. Seeds of castor bean plants of the Guarani, and IAC-80 cultivars were stored in two environments (cold room, and room conditions), using three package types (multifoliate Kraft paper bag, and polyethylene bag, and polyethylene bag with vacuum at 1 atm). In addition, another storage condition was evaluated: cryopreservation (-196 °C) in foil paper bags. Seed quality was evaluated before storage and at 4, 8, and 12 months after storage by testing their 7-day and 14-day germination, emergence, health, water content, and oil content. The experiment was conducted in a completely randomized design, with 7×4 factorial arrangement consisting of seven storage conditions and four evaluation times. Cryopreservation is the ideal condition for maintaining the seed physiological quality of the Ricinus communis cultivars used throughout storage. The oil content of the R. communis seeds decreases, and the incidence of Aspergillus spp. and Fusarium spp. fungi increases throughout storage, regardless of the storage conditions.
