“…It is an annual crop with great importance as an alternative winter crop, especially in southern Brazil (Crestani et al, 2010), also reaching areas in the CentralWest region. In the areas of expansion of oats cultivation, the main goal is to maintain ground cover for the formation of biomass and grain production in no-tillage system (Castro et al, 2012).…”

White oat is an excellent alternative winter crop for crop rotation systems. The decomposition of organic matter retained on the soil in no-till conditions associated with poor drainage or excessive moisture increase the formation of organic acids, including acetic and butyric acids, with high phytotoxic potential. This study aimed to evaluate the effect of acetic and butyric acids on germination and early seedling development of different oat cultivars. The experiment was a completely randomized block design, where seeds of the cultivars Afrodite, Albasul, Brisasul, FAEM 06, IAC 7, URS 21 and URS Taura, were subjected to four levels of acetic (0, 4, 8 and 12 mM) and butyric (0, 3, 6 and 9 mM) acids. Seeds were kept in a germination chamber for ten days. The traits evaluated were: shoot length (SL), root length (RL), and germination percentage (% GER). Butyric acid was more toxic than acetic acid, impairing more root development than shoot length. The cultivars IAC 7 and Brisasul were more sensitive and the cultivars URS Taura and Afrodite were tolerant to the organic acids studied. In the control and in the treatment with 12 mM acetic acid, we found correlation between RL and %GER. There is a large variation among cultivars in response to acetic and butyric acids.Key words: phytotoxicity, Avena sativa, germination, root, shoot. Resposta de plântulas de aveia ao estresse por ácidos acético e butíricoResumo A aveia branca é uma excelente opção como cultura de inverno em sistemas de sucessão de culturas. A decomposição do material orgânico, mantido na superfície do solo no plantio direto, associado a condições de má drenagem ou umidade excessiva, acentua a formação de ácidos orgânicos. Dentre estes, os ácidos acéticos e butírico apresentam grande potencial fitotóxico. O objetivo do trabalho foi avaliar o efeito dos ácidos acético e butírico na germinação e no desenvolvimento inicial de plântulas de diferentes cultivares de aveia branca. O experimento foi conduzido em blocos completamente casualizados, onde sementes das cultivares Afrodite, Albasul, Brisasul, FAEM 06, IAC 7, URS 21 e URS Taura foram embebidas em quatro doses de ácido acético (0, 4, 8 e 12 mM) e butírico (0, 3, 6 e 9 mM). As sementes foram mantidas em câmera de germinação por dez dias. Foram avaliados os caracteres comprimento da parte aérea (CPA), comprimento de raiz (CR) e a porcentagem de germinação (% GER). O ácido butírico demonstrou-se mais fitotóxico que o ácido acético, sendo o desenvolvimento das raízes mais afetado que a parte aérea. As cultivares IAC 7 e Brisasul demonstraram-se mais sensíveis e as cultivares URS Taura e Afrodite demonstraram-se menos afetadas pelos ácidos orgânicos em estudo. Sem a adição de ácidos e na dose de 12 mM de ácido acético, verificou-se a correlação entre % GER e CR. Existe grande variabilidade entre as cultivares estudadas, em resposta aos ácidos acético e butírico.

“…Studying the culture of white oats, researchers have been observing effects pronounced of genotype x environment interaction, concluding that the year of cultivation is the principal factor contributing to the instability of production [6] [21] [22]. Therefore, in addition to the performance per se, the understanding of the effects of the interaction genotype versus environment becomes necessary [6]- [23].…”

“…The inclusion of oats in the diet has grown tremendously in recent years due to more demanding population and seeking more nutritious and healthy foods [6] [7]. On the other hand, oat consumption is based product "in natura" that after peeling is directed production bran, flour or flakes, implying greater care in the production process, especially in the use of agrochemicals to control fungal diseases.…”

“…In modern agriculture, the recommendation of cultivars with high grain yield and with stability to climatic variations is decisive, by taking advantage of improved environments or that showing adequate performance under adverse conditions [6]- [18]. Like this, the identification of genotypes of oats of high performance in characters of agronomic interest and industry, less demanding the use of fungicide and with adaptability and stability, may favor a more sustainable production of oat cultivation.…”

The use of productive cultivars with adaptability and stability and less demanding to fungicide use are critical to the sustainability of production factors. The objective of this work was to determine the per se performance of white oat cultivars and parameters of adaptability and stability on yield and grain quality in the proposition of cultivars more responsive in reducing the use fungicide. The study was conducted in Augusto Pestana, RS, Brazil, between the years 2010 and 2013. The experimental design was randomized blocks with six replicates, three with and three without fungicide. The study evaluated 14 white oat cultivars for yield and industrial capability. The white oat cultivars FAEM 4 Carlasul and URS Corona indicate high grain yield with stability and general adaptability, independent of chemical control. The cultivar URS Corona shows together high yield and thousand grain weight and hectoliter with general adaptability and stability in the absence of fungicide. Although no stability has been detected in industrial yield without the use of fungicides, cultivars of URS Charrua, URS Corona and URS Taura show high means with general adaptability.
