Studies on the basidial Formation by Sclerotium rolfsii Sacc XII. A Discussion on the basidial Stage of Sclerotium Rolfsii Sacc. Isolates and its Identity
In the earlier papers (Series I to XI, 1965) the authors had already reported the success obtained in getting basidial stage of Sclerotium rolfsii Sacc. isolates from potato, Colocasia and groundnut (Arachis hypogea L.) and media as well as conditions under which these stages could be obtained. It is proposed to review these in this paper and discuss in detail the basidial stage of S. rolfsii a...
متن کاملOccurrence of Sclerotium Rot in Allium tuberosum Caused by Sclerotium rolfsii in Korea
In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the sca...
متن کاملFirst Report of Sclerotium Rot on Cymbidium Orchids Caused by Sclerotium rolfsii in Korea
Sclerotium rot was found on Cymbidium orchids at Seosan-si, Chungcheongnam-do, Korea, in July, 2010. Symptoms occurred on low leaves, which turned yellowish, after which the entire plant wilted. Severely infected plants were blighted and eventually died. White mycelial mats and sclerotia appeared on pseudobulbs. Based on the mycological characteristics and pathogenicity, the causal fungus was i...
متن کاملSelection of high temperature and salinity tolerant Trichoderma isolates with antagonistic activity against Sclerotium rolfsii
Trichoderma isolates were collected from varied agro-climatic zones of India and screened for high temperature and salinity tolerance. Among all the isolates tested, T. asperellum, TaDOR673 was highly tolerant to heat shock of 52°C with a mean spore count (log c.f.u/ml) of 4.33. The isolate after recovery from heat shock possessed higher germination rate and biomass production compared to its w...
متن کاملSclerotium Rolfsii Sacc. in Perfect Stage Vii. Germination of Basidiospores
In nature Sclerotium Rolfsii attacks the hosts usually at their foot. In a case was observed by the author a Hibiscus plant attacked at about a meter above the ground. By what means the pathogene reached at that height is still unknown. It may be possible that the infection has been caused by basidiospores transported by flow of air. It is therefore interesting to know the relation of germinati...
