Accelerated<br />or rapid aging methods is expected to serve seeds with different viabilities for those studies. The objective of this study was to<br />obtain efficient seeds rapid aging method of rice seeds. The study consisted of three experiments i.e. rapid aging with ethanol<br />gas, soaking seed in liquid ethanol (96%) and exposing seeds to 41 oC temperature and ± 100% relative humidity. Each<br />experiment was arranged in a randomized block design with single factor that was length of aging with three replications.<br />There were eight rice varieties used in this study, i. e. three varieties of upland rice, two verieties of lowland rice, and three<br />varieties of swamp rice. The results showed that the physical aging method could not produce reliable data due to fungus<br />infection on the treated seed. It was found that generally 60% and 50% viabilities of rice seed could be obtain by ethanol gas<br />treatment for 4.9 and 5.3 hours, as well as by liquid ethanol for 4.0 and 4.4 minutes, respectively. Rapid aging method with<br />liquid ethanol was the fastest and simplest method for decreasing seed viability of rice.<br />Keywords: Ethanol, rapid aging, invigoration, seed viability</p&gt;}, number={1}, journal={Jurnal Agronomi Indonesia (Indonesian Journal of Agronomy)}, author={BeloSimão Margono}, year={2017}, month={Jan.} }
