Modelos de pontos críticos para relacionar o rendimento de grãos de aveia branca com a intensidade de doença no patossistema múltiplo ferrugem da folha: helmintosporiose Critical-point models to relate white oat yield and disease intensity of the multiple pathosystem leaf rust: helminthosporium blight

Ciência Rural, 2010
A ferrugem da folha e a helmintosporiose são as principais doenças fúngicas foliares de aveia branca. Em cultivares suscetíveis, o controle químico não considera o limiar de dano econômico (LDE).

Carotenoid pigments of the spores of Puccinia coronata and Stereostratum corticioides

Japanese Journal of Phytopathology, 1961
Some qualitative and quantitative studies of the carotenoid pigments were made with uredospores of Puccinia coronata Corda, uredospores and teleutospores of Stereostratum corticioides (Berk. et Br.) Magnus. The major pigment of all samples is γ-carotene, constituting about 60per cent of total carotenoids, and β-carotene comes next excepting uredospores

Influence de la température, de la lumière et de la nutrition minérale sur l'expression de la résistance du kénaf (Hibiscus cannabinus L.) à l'anthracnose (Colletotrichum hibisci Poll.) [PDF]

, 1978
La température joue un rôle important dans l'expression de la résistance du kénaf à l'anthracnose. A 15 °C et à 20 °C, il n'y a pas de différences entre la sensibilité d'une variété sensible et celle d'une variété résistante.

Analysis of the Involvement of Hydroxyanthranilate Hydroxycinnamoyltransferase and Caffeoyl-CoA 3-O-Methyltransferase in Phytoalexin Biosynthesis in Oat

Molecular Plant-Microbe Interactions, 2004
Two oat genes encoding hydroxycinnamoyl-CoA:hydroxyanthranilate N-hydroxycinnamoyltransferase (HHT) and S-adenosyl-l-methionine:trans-caffeoyl-CoA 3-O-methyltransferase (CCoAOMT), both of which are possibly involved in the biosynthesis of oat ...
