Abstract:
Brown spot of pear is a fungal disease caused by Stemphylium vesicarium. Currently, the disease control efficacy is limited, due to the characteristics of disease and the reduction of the allowed fungicides. Therefore, this thesis is focused on finding new compounds to be applied alternatively or as a complement to the existing fungicides. Thus, twelve synthetic antifungal peptides selected from CECMEL11 library were evaluated in vitro against S. vesicarium. The most effective peptide was BP15 with a minimum inhibitory concentration (MIC) of 10 µM. Moreover, the peptide reduced significantly t

In recent years two new diseases, brown spot and black pit, have been observed on potatoes in South Africa. Brown spot symptoms appear on the foliage as small brown lesions, whereas black pit symptoms appear on the tubers as small dark sunken lesions. In this study the causal organism of brown spot and black pit of potatoes in South Africa was determined. During initial isolation, one fungus and two bacteria were isolated, which were included in the trial. Only the treatments where the fungal isolate was used in inoculation resulted in the development of brown spot lesions. The causal organis

Symptoms consisted of brown spot, curling of the tissues, sometimes even shrinking and cracking of the infected fruit bodies. Ten isolates, GR-6、GR-7、GR-12、GR-13、GR-16、GR-18、GR-23、GR-28、GR-31 and GR-37 were isolated from diseased fruiting bodies. Pathogenicity was confirmed by inoculating the fungus onto fruit-bodies of P. eryngii for 3 - 4 days under high hum

碩士<br>國立臺南藝術大學<br>博物館學與古物維護研究所<br>102<br>There are multiple factors must be considered while facing the deterioration of an object. This research aims at the cause of brown spots on gofun paint, by a case study of glue painting. Through examinations, it is preliminarily speculated that there are some characteristic of biodeterioration on the gufan painted surface, like round, irregular shape of losses, spots with fluorescent reaction, unknown black flyspecks and holes on the silk. We can also surmise from the process of pigment-mixing may have some flaws that result in the loss on the pain
