The fungous pathogens of rice blast disease and crab grass blast disease are close members in the same genus, Pyricularia. P. oryzae Cavara is usualy parasitic on rice and P. grisea (Cke. ) Sace. on other cereals and grasses. Besides the morphological differentiation of the two organism, rapid detection may be used by treating the conidia with 80% hydrochloric acid and staining with alcohol solutions of 1% brilliant green, 0.1% cotton blue or 0.2% safranine T. After staining, there will be plasmolysis...

The fungous pathogens of rice blast disease and crab grass blast disease are close members in the same genus, Pyricularia. P. oryzae Cavara is usualy parasitic on rice and P. grisea (Cke. ) Sace. on other cereals and grasses. Besides the morphological differentiation of the two organism, rapid detection may be used by treating the conidia with 80% hydrochloric acid and staining with alcohol solutions of 1% brilliant green, 0.1% cotton blue or 0.2% safranine T. After staining, there will be plasmolysis of conidial cells in P. oryzae but no such reaction in P. grisea. P. grisea may came panicle blast of rice, but it can not infect rice leaves.

稻瘟病菌(Pyricularia oryzae Cavara)与杂草马唐瘟菌(P.grisea [(Cke.)Sacc.]均包含在Pyricularia属内。两菌除从形态学上进行区分外,快速鉴定法可用80%盐酸处理两菌的分生孢子,再用1%亮绿,或0.1%棉兰,或0.2%碱性藏红3种染料的酒精溶液处理。在稻瘟病菌分生孢子的细胞中,明显地出现原生质向细胞中央浓缩的质壁分离现象,而马唐瘟菌则无明显反应。马唐瘟菌可以引致水稻穗颈瘟,却很少侵染叶片产生叶瘟。

This paper reports that the fungus causing greasy yellow spot of citrusin China is identified as Mycosphaerella citri whiteside.Its pseudoperitheciaoccur in fallen decomposing citrus leaves and ascospores are the major sourceof peimary infection.The imperfect state of this fungus which occurs on livi-ng leaves and cultural media is recognized as Stenella citri-grisea(Fisher)Sivanesan.Inoculum for pathogenicity study indicates that the fungus hyphaepenetrate citrus leaves through stomata,the incubation period is 1-2 monthsor more which is related to the resistance of citrus varieties. In citrus groves around Taihu Lake of Jiangsu,mycelium of this funguspersistes in citrus leaves and twigs as over wintering state.when temperaturearises to 20℃ and season of rain comes in next year,ascospores dischargedfrom fallen decomposing leaves begin to infect citrus leaves and symptom va-ries according to different period leaves of citrus.

根据对采自江、浙、黔、川、滇等省部分产桔区的病叶进行分离培养和接种的研究,证明上述各地都有柑桔脂点黄斑病发生。本病症状初呈黄斑,后转为脂斑,有时可进而转变成褐色小园星。病原菌为柑桔球腔菌(My-cosphaerella citri Whiteside),无性阶段为柑桔灰色疣丝孢(Stenella citri-grisea(Fisher)Sivanesan),其主要形态特征与J.O.Whiteside报道的美国佛罗里达州柑桔脂斑病病原菌基本相同,但接种后表现的病状有所差异。病菌的假囊壳产生在落地将朽的病叶上,子囊孢子起着初侵染作用;发生在落叶上的分生孢子数量很少,看来再侵染作用不大,但在培养基上可产生较多的无性孢子.接种表明,病菌从寄主的气孔侵入,潜育期1~2个月以上,其长短与柑桔品种有关,在江苏太湖桔区,此菌主要以菌丝体在病叶中越冬,翌年4—9月间落叶上产生子囊孢子传播侵染,春、夏、秋、梢的新叶均可受害,以春梢叶片被害最重.

The isolates of Pyricularia grisea Saccardo were obtained from finger-grass, wire griss, African millet and rice in Yunnan and their conidiospore size, infection by cross-inoculating and perfect state formation were studied. The results showed that the isolates from these host plants all shoud be classified same species into Pyricularia grisea Saccardo as their morpholo-gicl characters in imoerfect state were very much alike. Exeept finger-grass, the mutual mating among isolates, which produced fertile ascospore, was available. However, the pathogenicity of isolates were apoarently different. Wire grass and African millet could be infected alterlately by their isolates but to rice and fingergrass. These isolates had no pathogenicity. Isolates from rice and fingergrass only infected their own host plants respectively. It is sugested that Man-aporthe grisea (Hebert) Barr should be used as the scintific name rice blast disease of fungus in perfect stage, and Pyricularia grisea Sccardo as in imperfect stage.

为了解稻瘟病菌的寄主范围和有性世代形成生境,笔者研究了云南省内采集的马唐、蟋蟀草、龙爪稷及水稻上分离的Pyricularia菌作了分生孢子大小的比较、交互感染接种试验及有性世代形成状况的研究,结果表明:这几种寄主植物的分离菌应属同一个种,它们无性阶段的分生孢子形态十分一致,除马唐菌原外,它们可以相互交配,产生子囊孢子,但致病性有差异;蟋蟀草分离菌与龙爪稷分离菌可以交互感染,但对水稻、马唐无致病性;水稻、马唐分离菌仅能使分离寄主发病。文章还对该种菌的学名作了讨论,建议我国使用Pyricularia grisea(Cooke)Saccardo作为稻瘟病菌无性时期的学名,有性时期学名使用Magnaporthe grisea(Hebert)Barr comb.nov.
