“…This was even comparable with earlier results of some of the researchers (Pensuk et al, 2002;Buiel and Parlevliet, 1996) who reported the disadvantage of using disease severity scoring due to the highly variable symptoms caused by GBNV that are not primarily genotype specific. Disease incidence is more advantageous than disease score because it is easy to evaluate (Kesmala et al, 2006).…”

“…At 1:100 virus concentrations, these genotypes showed moderately resistant and moderately susceptible disease reaction except ICR 48 which showed susceptible disease reaction. (Buiel and Parlevliet, 1996). Disease incidence decreased and incubation period increased with the age of plants and leaves.…”

“…There is no practically feasible control measure currently available for GBNV in groundnut. However, by using certain cultural practices such as adjustment of planting date coinciding with low levels of thrips activity, intercropping with fast growing cereals (Reddy et al, 2000) and close planting (Basu, 1995;Buiel and Parlevliet, 1996;Wongkaew, 1995), the disease incidence can be reduced. Control of this virus disease through crop rotation and removal of alternate weed hosts have met with limited success (Rao et al, 2013).…”

“…Resistant genotypes reduced the rate of epidemic development with considerable reduction in the incidence of GBNV (Culbreath et al, 1993;Buiel and Parlevliet, 1996). So, the genotypes showing high resistance or resistance response could be used as seed material after screening of genotypes further in different trials.…”

“…Buiel and Parlevliet (1996) also reported a significant reduction in the incidence of the peanut bud necrosis virus (PBNV) as infected plants aged. The incidence of diseased plants in the genotypes tested dropped significantly as the plants aged.…”

ABSTRACT. The aim of this study was to clarify the relationship between soybean leaf/plant age and the susceptibility to infection by Phakopsora pachyrhizi. Two studies were conducted in the greenhouse during the 2009/2010 season using the BRS 232 cultivar. The experimental design for Study 1 was fully randomized in a 2 x 3 factorial arrangement (phenological stage x age of the 4th, 5th and 6th trifoliate at the time of inoculation), and in Study 2, the experimental design was fully randomized with five treatments (T) and four replicates. The variables assessed were disease severity, number of lesions, uredinia per lesion, and viable spores. In Study 1, it was observed that disease severity was lower when the plant was in the growth stage V6 (11.4%), compared to the reproductive stage R4 (16.9%). The regression for disease severity and leaf age at the time of inoculation showed that older trifoliates on the plants in the reproductive stage exhibited higher severity. However, in Study 2, for trifoliates of the same age on plants of different ages, the trifoliates of younger plants were more susceptible to the disease. It was concluded that soybean plant susceptibility to soybean rust was directly proportional to the age of the trifoliate on a given plant and the phenological stage of the plant at the time of inoculation.Keywords: Phakopsora pachyrhizi, phenological stage, age of trifoliates.Tecidos de folha velha em plantas mais jovens são mais suscetíveis à ferrugem da soja RESUMO. O objetivo do estudo foi esclarecer a relação entre a idade da folha/planta e susceptibilidade à infecção de Phakopsora pachyrhizi. Foram conduzidos dois estudos em cada de vegetação durante a safra 2009/2010 utilizando a cultivar BRS 232. O delineamento experimental do Estudo 1 foi inteiramente casualizado em arranjo fatorial 2 x 3 (Estágio fenológico x idade do 4th, 5th e 6th trifólio no momento da inoculação), e Estudo 2, delineamento inteiramente casualizado com cinco tratamentos (T) e quatro repetições. As variáveis avaliadas foram severidade da doença, numero de lesões, urédias por lesão e esporos viáveis. No Estudo 1 foi observado que severidade da doença foi menor quando as plantas estavam no estágio de crescimento V6 (11,4 %), comparado com estágio reprodutivo R4 (16,9%). A regressão para severidade da doença e idade da folha no momento de inoculação mostrou que trifólios mais velhos em plantas no estágio reprodutivo exibiram maior severidade. Contudo, no estudo 2, para trifólios com a mesma idade em plantas de diferentes idades, os trifólios de plantas jovens foram mais susceptíveis à doença. Conclui-se que a suscetibilidade de plantas a ferrugem asiática foi diretamente proporcional à idade do trifólio em uma dada planta e o estágio fenológico no momento de inoculação.Palavras-chave: Phakopsora pachyrhizi, estágio fenológico, idade do trifólio.
