Tsay, J. G., and
Hsieh, W. H. 1993. Some new recorded Diaporthe fungi from Taiwan. J. Chia-Yi
Ins. Agr.(Taiwan, R.O.C.) 34: 81-92.
Altogether
thirty-seven specimens belong to Diaporthe were collected from July,
1990 to December, 1991. Six Diaporthe fungi new records from Taiwan are
described. These are Diaporthe arctii (Lasch) Nitschke, D. conorum
(Desmazieres) Niessl, D. eres Nitschke, D. nomurai Hara, D. pustulata
(Desmazieres) Saccardo, and D. spiculosa (Albertini et
Schweinitz) Nitschke.
(Key words: Diaprothe,
Taiwan)
INTRODUCTION
The Diaporthaceae
form their perithecia immersed in a stroma with only their long beaks
protruding. The ascus has an apical refractive ring. The ascospores are hyaline
and two-celled. The largest genus in this family is Diaporthe. There are
a direct correlation between ascigerous and conidial stages. The imperfect
stage of Diaporthe species all belong to the form-genus Phomopsis (1).
According to the
List of Plant Diseases in Taiwan(2), Diaporthe citri, D. pomigena,
D. vexans and 12 species of Phomopsis were recorded in Taiwan.
Two monographs of Diaporthe had been published in other countries(2,4).
The purpose of this study deals with the general survey of Diaporthe in
Taiwan. The delimited works are based on the Kobayashi(2) and Wehmeyer(4).
MATERIALS AND METHODS
The materials were
collected from various location in Taiwan from July, 1990 to December,
1991(Table 1). All collections were made with the dead twigs by keeping them in
paper bags at room temperature. Measurements of conidia, perithecia, asci, and
ascospores were made over twenty replications as possible for the fungus on
twig. All specimens were drawed under 150 X and 600 X magnification of Olympus
microscope with the aid of micrometer and Olympus drawing tube. Herbarium
packets were labeled with host species, fungal species, collector, collection
date, collection area. All specimens collected have been deposited at the
mycology laboratory of Department of Plant Pathology, National Chung Hsing
University.
