Respiration during Germination in Uredospores of Puccinia coronata
Japanese Journal of Phytopathology, 1967 Respiration during the germination of Puccinia coronata uredospores was studied by floating the spores on liquid in Warburg flask of about 18ml volume. The respiratory rate (Qo2) on distiled water declines gradually during incubation at 25°C except when germination is very favourable due to a light load of spores (1.5mg spores per 2ml), in which a ...

Self-inhibition in the uredospore germination of Puccinia coronata
Japanese Journal of Phytopathology, 1959 Some inconsistent results from germination studies of rust spores have been recently explained on the basis of self-inhibitors. The present study was performed to make clear the self-inhibition in the uredospore germination of Puccinia coronata Corda. The samples of spores were harvested by shaking the rusted leaves which had been collected from field ...

Mating type of isolates derived from the spermogonial state of Puccinia coronata var. coronata
Mycoscience, 1994 Hyphal confrontation between two haploid cultures originating from single basidiospores was used to determine the mating type ofPuccinia coronata var.coronata. Pairs of 15 single-basidiospore cultures were placed approximately 1 mm apart on the medium in all possible combinations. Hyphae of the pairs of colonies came into contact with each other in all

Preliminary screening of Avena sterilis L. for resistance to crown rust
Agronomy Science, 2020 The best source of crown rust resistance genes (Pc) in genus Avena is a wild hexaploid A. sterilis L. In this study, accessions of A. sterilis gathered from European and North American gene banks, originated from 21 countries were evaluated at the ...

Genetic progress from 15 years of white oat breeding in Brazil
Crop Science, Volume 66, Issue 3, May/June 2026.Abstract Despite advances in crop management and breeding, cereals still face considerable yield losses from phytopathogens and lodging caused by adverse weather. Developing oat genotypes that combine disease tolerance, lodging resistance, and industrial quality is therefore essential, and the estimation of genetic progress allows validation of ...
