Qualidade fisiológica de sementes de mamona classificadas por tamanho

Abstract: Termos para indexação: Ricinus communis L., beneficiamento, peneira, germinação. PhYSIOLOgICAL quALITY Of CASTOR BEAN SEEdS CLASSIfIEd BY SIzEABStRACt -Seed size in many species may be an indication of their physiological quality. the objective of this study was to evaluate the physiological performance of castor bean seeds sorted by size. The experiment was conducted at the Seed Research Laboratory of the department of Plant Science at the Federal University of Viçosa. Seeds of four castor bean cultivars, IAC… Show more

“…De maneira diferente, Zuchi et al (2010) verificaram que o teste de envelhecimento acelerado a 42 °C/48 h e 100% de umidade relativa, foi eficiente em classificar lotes de sementes de mamona cv. IAC-226 em diferentes níveis de vigor.…”

“…Germination (G), germination speed index (GSI), shoot dry mass (SDM) and root (SDR) as a function of the sieve, and root length (RL) as a function of the cultivar. Em algumas espécies como a soja (Glycine max) e mamona (Ricinus communis), o tamanho da semente influencia o sucesso da germinação (PÁDUA et al, 2010;ZUCHI et al, 2010). Para o trigo sarraceno as sementes menores podem estar imaturas, e com menores quantidades de reserva, consequentemente, não dão suporte suficiente para a germinação.…”

“…Ferreira and Sá (2010) also verified an enhancement in the quality of corn seeds subjected to processing. Zuchi et al (2010) observed that the size of castor seeds influenced their physiological performance. In cultivars IAC 226 and BRS 188 Paraguaçu, the small ones exhibited the highest values of germination speed and final germination percentage.…”
