广东省凤梨科观赏植物真菌病害鉴定

为给观赏植物病害的防治提供科学依据,根据病害症状和病原菌的形态特征以及有关文献的分类系统,鉴定了1998-2000年在广东调查的12种凤梨科观赏植物真菌病害,即围小丛壳[Glomerrellacinghlata(Stonem.)Spauld.etSchrenk]、辣椒刺盘孢[Colletotrichumcapsici(Syd.)Butl.etBisby]、水塔花星裂盘菌(PhacidiumbillergiaeL.ZengetP.K.Chi)、凤梨顶多毛孢菌(BartaliniaananassaL.Zeng,Z.D.JiangetP.K.Chi)、可可球二孢(BotryodiplodiatheobromaePat.)、钝头粘盘孢菌(ColletogloeumobtusumSutton)、油球拟茎点霉[Phomopsisdiplodinoides(Sacc.)Punith.]、筒凤梨拟茎点霉(PhomopsisspectabilisV.G.Rao&B.R.D.Yadav)引起的叶斑病,灰霉(BotrytiscinereaPers.)引起的花腐及分别由强雄腐霉(PythiumarrhenomanesDrechsler)、簇囊腐霉(PythiumtorulosumCoker&Patterson)和蕨柱帚霉(Cylindrocladiumpteridis Wolf)引起的根茎腐、叶基茎基腐和茎基腐。其中,星裂盘菌叶斑病、顶多毛孢叶斑病为凤梨科观赏植物的新病害;钝头粘盘孢菌、油球拟茎点霉为中国真菌新记录种。在温室生产中,以围小丛壳引起的叶炭疽病、筒凤梨拟茎点霉引起的叶斑病发生普遍而严重;根茎腐、叶基茎基腐和茎基腐在部分生产单位常引起死苗或死株

Identification of the Fungal Diseases in Ornamental Plants of Bromeliceae in Guangdong Province

Twelve fungal diseases in ornamental plants of Bromeliaceae were identified by systematic investigation carried out from 1998 to 2000 in Guangdong Province. They were leaf spots caused by Glomerrella cingulata (Stonem. )Spauld. et Schrenk, Colletotrichum capsici (Syd.) Butl. et Bisby, Phacidium billergiae L. Zeng et P.Chi, Bartalinia ananassa L. Zeng,D. Jiang et P. K. Chi, Botryodiplodia theobromae Pat., Colletogloeum obtusum Sutton, Phomopsis diplodinoides (Sacc.) Punith., Phomopsis spectabilis V. G. Rao B. R. D. Yadav,flower rot by Botrytis cinerea Pers., basal stem rot and leaf base rot by Pythium arrhenomanes Drechsler, Pythium torulosum Coker& Patterson and Cylindrocladi pteridis Wolf. Leaf spots caused by Phacidium billergiae and Bartalinia ananas are new diseases in ornamental of Bromeliaceae. Colletogloeum obtusum and Phomopsis diplodinoides were species newly recorded in China. Anthracnose caused by Glomerrella cingulata and leaf spot.Phomopsis spectabilis were serious and popular diseases in greenhouse. Basal root and stem rot, basal leaf and stem rot and basal stem rot caused by Pythium spp. and Cylindrocladium pteridis often brought about plant death in some gardens.
