Non-thermal energy sources have been utilized to control diseases and boost the physiological quality of maize seeds. The aim of this paper was to assess the impact of UV-c exposure and ozone application, associated or not, on organic maize seed germination and seedling vigor. Three cultivars (BRS Caimbé, BRS 1060 and BR 451), three exposure levels to ozone (15, 30 and 60 minutes) in the absence and presence of ultraviolet radiation (UV-c), were used in a completely randomized design with a factorial scheme of 3 x 3 x 2 + 3 (additional treatments) experiment. Evaluations of electrical conductivity, emergence in soil, and germination (at 4th and 7th day) on paper roll were done. Daily measurements of the emerged seedlings were taken up to the 14th day after emergence. The measurements included total emergence (EC), coefficient of variation in emergence time (CVt) in percentage, coefficient of emergence velocity (CVe) in percentage, emergence rate index (ERI) in days, and emergence synchronization index (Z). The tested genotypes caused differences in all studied variables. Increasing the percentage with a 30-minute exposure to ozone in the presence of UV-C radiation resulted in a validated enhance in the first germination reading. The association of O3 and UV-c techniques can be used to treat organic maize seeds without significantly affecting their physiological quality. |

Abstract: The objective of this study was to compare the corn-based (FLU), high linoleic acid flushings(LAF), and a control treatment (un supplemented, CON); two genetic groups:Morada Nova (MN) and Brazilian Somalis (BS), on the productive and reproductive performance of ewes and their lambs. A total of 156 non-pregnant ewes were supplemented three weeks before and after the breeding season. Supplementation with either FLU or LAF increased ewe body condition score (BCS) at the beginning of the breeding season and at lambing compared to CON. The BS ewes had greater body weights at the supplementation end, and BCS both at the supplementation start, and at lambing compared to MN. Similarly, ewes with three lambs per birth had greater BCS at the beginning of supplementation. They also had greater weights at the beginning of the breeding season and at lambing. Both FLU and LAF increased total lamb weight from 56 to 105 days of age compared to CON.The BS ewes had decreased prolificity and produced lower total weight of lambs at lambing, but greater 84 and 105 days after birth compared to MN. Total lambweight at birth was greater for ewes that lambed three, followed by two and then one lamb per birth. In conclusion, the high linoleic acid and high corn supplementation increase body condition score of ewes form breeding season to lambing and enhance lamb performance after 56 days of age. Although Morada Nova ewes increased prolificacy, their lambs were lighter after they reached 84 days of age. [Flushing à base de milho ou alto ácido linoleico aumenta a produtividade de ovelhas Morada Nova e Somalis Brasileira]. Resumo: O objetivo deste estudo foi comparar flushings à base de milho (FLU), ácido linoleico alto (FAL), e tratamento controle (não suplementado, CON);dois grupos genéticos: Morada Nova (MN) e Somalis Brasileiro (SB), sobre desempenho de ovelhas e cordeiros. Foram suplementadas 156 ovelhas não prenhes três semanas antes e após a estação de monta. Tanto FLU quanto FAL aumentaram o escore de condição corporal (ECC) de ovelhas no início da estação de monta e no parto, comparado ao CON. Ovelhas da raça SB tiveram maior peso no final da suplementação, e ECC, tanto no início da suplementação, quanto ao parto comparado ao MN. Da mesma forma, ovelhas com três cordeiros por nascimento tiveram ECC maior no início da suplementação. Elas também tiveram maiores pesos tanto no início da estação como no parto. Tanto FLU como FAL aumentaram o peso do cordeiro de 56 até 105 dias de idade comparadoao CON. Ovelhas SB diminuíram a prolificidade e produziram menor peso total de cordeiros ao parto, porém maior peso totalapós 84 e 105 dias comparado às ovelhas MN. O peso totaldecordeiros ao nascimento foi maior para ovelhas com gestação tripla, seguido por dupla, e simples. Em conclusão, a suplementação com ácido linoleico e milho aumentam o escore da condição corporal de ovelhas desde a estação de monta até o parto e a performance do cordeiro após 56 dias de idade. Embora ovelhas Morada Nova tenham aumentado a prolificidade, seus cordeiros ficaram mais leves apósos 84 dias de idade.
