Pathogenic fungi found in wheat seeds and medium early maturity, produced in three parts of Rio Grande do Sul, Brazil
Descripción del Articulo
Seed samples of wheat harvest in 2010 from Santo Augusto, Passo Fundo and Vacaria, RS; were plated on gerbox acrylic sterilized culture medium PSA (potato, sucrose and agar) plus antibiotics. Were used 400 seeds of each cultivar total of 45 cultivars. Were distributed equally spaced 25 seeds in each...

Were used 400 seeds of each cultivar total of 45 cultivars. Were distributed equally spaced 25 seeds in each seedling with four replications, totaling 100 seeds per replicate. The seeds were incubated at 25 ± 2°C in an incubator with a photoperiod of 12 hours for 12 days. The experimental design was blocks and the experimental unit consists of four gerbox containing 25 seeds each.

The data were transformed to (x+1)1/2 and subjected to analysis of variance and means compared by Tukey test at 5% probability. Fungi F. graminearum and Alternaria spp. were detected in high incidence in most lots, performing at respectively 96.0% and 98.0% of samples, thereafter Bipolaris spp. So too, Drechslera siccans was found in 41.5% of samples showing that their incidence is increasing.

Foram utilizadas 400 sementes de cada amostra, totalizando 45 cultivares. As sementes foram incubadas a 25 ± 2 °C em câmara climatizada com fotoperíodo de 12 horas durante 12 dias. O delineamento experimental foi de blocos casualizados e a unidade experimental constituída por 4 gerboxes contendo 25 sementes cada.

Os fungos F. graminearum e Alternaria spp. foram detectados em alta incidência na maioria dos lotes, apresentando-se respectivamente em 96.0 % e 98.0 % das amostras analisadas, seguidamente de Bipolaris spp. Assim também, Drechslera siccans foi encontrada em 41,5% das amostras, evidenciando que sua ocorrência vem aumentando.Universidad Nacional de Trujillo2012-04-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/6510.17268/sci.agropecu.2012.01.09Scientia Agropecuaria; Vol. 3 No. 1 (2012): January - March; 67-74Scientia Agropecuaria; Vol. 3 Núm. 1 (2012): Enero - Marzo; 67-742306-67412077-9917reponame:Revista UNITRU - Scientia Agropecuariainstname:Universidad Nacional de Trujilloinstacron:UNITRUspahttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/65/80Derechos de autor 2012 Scientia Agropecuariainfo:eu-repo/semantics/openAccess2021-06-01T15:35:14Zmail@mail.com - |
