广东省人心果病原真菌研究

STUDIES ON PATHOGENIC FUNGI ON Achras sapotae L IN GUANGDONG PROVINCE

２年来对我省人心果真菌病害的系统调查表明：人心果生长期以枝叶病害为主，果实病害主要发生于贮藏期；生长期病害中影响生产最大的是炭疽病，引起枝叶枯死。本文报道了人心果的病原真菌８种，其中２个新种，它们是ＤｉｄｙｍｅｌｌａｓａｐｏｔａｅＣ．Ｆ．ＺｈａｎｇｅｔＰ．Ｋ．Ｃｈｉ，ｓｐ．ｎｏｖ．，ＬｏｐｈｏｄｅｒｍｉｕｍｓａｐｏｔｉＣ．Ｆ．ＺｈａｎｇｅｔＰ．Ｋ．Ｃｈｉ．ｓｐ，ｎｏｖ．，其它病菌包括炭疽病菌、拟茎点霉枝枯病菌、焦腐病菌、拟盘多毛孢叶斑病菌、煤烟病菌和酸腐病菌，各病害的症状及病原特征均有详述。新种模式标本存放于本校植保系标本室内。

The results in two-year systematic investigation on the fungal diseases of Achras sapotae L. in Guangdong Province, showed that the diseases in branches and leaves were the major disease problems during the period of host growth; fruit diseases usually were found in the post-harvest duration;the most destructive disease was anthracnose which could cause a branch dead entirely. Eight species of pathogenic fungi were reported in this paper, two of them were new species to science,namely, Lophodermium sapoti C. F. Zhang et P.K.,Chi,sp. nov.and Didymella sapotae C.F.zhang et P.K.Chi, sp. nov., other species included Glomella cingulata(Stonem.) Spauld etShrenk,Phomopsis sapotae Lal & Rai,Chaetothyrium clavtisorum (Syd.)Hansford,Pestalotiopsis scirrofaciens(N.A. Brown)Y.X. Chen, Botryodipiodiatheobroniae Pat. and Geotrichum candium Link ex Pers. Bilingual discriptionin Latin and Chinese was given.The type specimens are deposited in the fungalcollection of Department of Plant Protection, South China AgriculturalUniversity.
