In 1962-1963,35 samples of Downy mildews collected from Brassica Pekinensis andother Cruciferous vegetables (including B.Chinensis,B.juncea,B.rapa,B.oleracea,Raphanussativus,and Capsella Bursa-Pastoris etc.) were identified with 32 differential hosts.Threevarieties of Peronospora parasitica were differentiated:P.p.brassicae on Brassica,P.p.raphani on Raphanus and P.p.capsellae on Capsella.In P.p.brassicae at least three differentforms existed (i.e.f.Pekenensis,f.olerasea,f.juncea).1.Collections from Brassica...

In 1962-1963,35 samples of Downy mildews collected from Brassica Pekinensis andother Cruciferous vegetables (including B.Chinensis,B.juncea,B.rapa,B.oleracea,Raphanussativus,and Capsella Bursa-Pastoris etc.) were identified with 32 differential hosts.Threevarieties of Peronospora parasitica were differentiated:P.p.brassicae on Brassica,P.p.raphani on Raphanus and P.p.capsellae on Capsella.In P.p.brassicae at least three differentforms existed (i.e.f.Pekenensis,f.olerasea,f.juncea).1.Collections from Brassica Pekinensis,B.Chinensis and B.rapa were found to belong tothe same group,since they infected all or a part of these hosts on which they all producedconidia.B.juncea var.megarrhisa showed varying reactions to these collections.No infec-tion took place on Capsella Bursa-Pastoris,Raphanus sativus,B.oleracea,B.juncea and B.juncea var.multiceps.Collections from different varieties of B.Pekinensis in different local-ities and seasons showed a remarkable difference in pathogenicity.2.The host ranges of the collections from B.juncea and B.juncea var.megarrhisa andvar.multiceps were limited to these plants,however,the collections from B.juncea did infectsome varieties of B.Pekinensis B.Chinensis and B.rapa.3.Collections from B.oleracea (including var.capitata,var.caularapa,var.alboglabra,var.botrytis) infected this species only and never infected other crucifers.4.Collections from Raphanus sativus were differentiated into two types,one infectedR.sativa only and the other infected some varieties of B.Pekinnensis,B.oleracea and B.rapaas well.5.Collections from Capsella Bursa-Pastoris only infected the original host but not others.

应用十字花科蔬菜三属七种32个品种作为鉴定寄主,对京津地区12种十字花科蔬菜(大白菜、油青菜、芜菁、芥菜、大头青、雪里蕻、甘兰、苤兰、花椰菜、芥兰、萝卜和荠菜)上采集的34个霜霉病菌(Pronospora parasitica(Pers.)Fr.)标样进行了生理分化的研究。得到以下结果:1.大白菜,油青菜,芜菁上的病菌为一类,它们可以侵染全部或部分的这类寄主,呈感病反应,产生孢子囊;芥菜对不同病菌标样呈抗病或感病反应;不侵染荠菜、萝卜、甘兰类和雪里蕻,大头青。不同时间、地点和不同大白莱品种上采集的菌种有较大的致病性差异。2.芥菜、雪里蕻、大头青上的菌种,除芥菜上的可以侵染大白菜、油青菜和芜菁的若干品种外,它们只侵染芥菜属寄主。3.甘兰类(包括甘兰,苤兰,芥兰和花椰菜)上的菌种只侵染本类寄主,呈感病反应,产生孢子囊;不能侵染其他种属寄主。4.萝卜上有两类菌种:一类仅侵染萝卜一属的品种,不能侵染其他属的寄主,但也发现有一个标样除本寄主外,尚可接种在芸苔属的大白菜、甘兰和芥菜的一部分品种上。5.荠菜上的菌种只能侵染荠菜,呈感病反应,而不能侵染其他寄主。

This paper makes a study of the biological characters of Botrytis cinerea Pers., which infected the leaves of the mulberry. The results could summarize as follows:1. The fungus had a capacity to grow from about 5 to 25℃, and the optimum temperture was at 20 to 25℃. When the temperature was below 10℃ the mycelia of this fungus could still proliferate, but could not from its conidia.2.

This paper makes a study of the biological characters of Botrytis cinerea Pers., which infected the leaves of the mulberry. The results could summarize as follows:1. The fungus had a capacity to grow from about 5 to 25℃, and the optimum temperture was at 20 to 25℃. When the temperature was below 10℃ the mycelia of this fungus could still proliferate, but could not from its conidia.2. The conidia germinated rapidly with a high germination rate in the presence of the mulberry leaf juice. The germination was markedly affected by the temperature. Investigations had confirmed the fact that below 7 ℃ and above 30℃ the germination rate was very low, and the optimum temperature lay between 20 and 25℃. However, if the conidia were collected from the field with the infected leaves in October and kept them indoors for the winter, they could not germinate in April next year.3. This fungus grew very well on the PAS or PDA medium containing the mulberry leaf juice. The optimun pH was neutural or slightly acid although the growth pH could be in the range of 4.4 to 9.0.4. The blacklight irradiation could promote the formation of the conidia.

桑树灰霉病病菌(Botytis cinerea Pers.)生长温度范围5~25℃,最适20~25℃,在10℃以下只能长菌丝,不长分生孢子。分生孢子在有桑叶汁液存在时,萌发快,萌发率高,萌发温度范围7~30℃;最适20~25℃。秋末(10月下旬)采集有分生孢子的病叶悬挂室内,翌年4月中、下旬分生孢子不能萌发,培养基以PSA加桑叶汁液及PDA加桑叶汁液对本病菌生长尤佳。病菌在pH4.4~9范国内均能生长,最适是中性到偏酸,黑光灯照射能促进本病菌分生孢子的形成。

A carbendazim(MBC)-resistant strain(R) of Botrytis cinerea was isolated from scallion in suburbs of Nanjing where it had been applied with MBC and thiophanates for several years. Mycelial growth of this Rstrain was less inhibited on repaired PSA with 1000μg/ml MBC (technical samples) and the MIC value was hardly measured. Myceliaof the sensitive strains of B.cinerea that were isolated from scallion, plum, strawherry, cabbage, however, can not grow on the PSA containing 0.5μg/ml carbendazim. The MBC-resistant(R)...

A carbendazim(MBC)-resistant strain(R) of Botrytis cinerea was isolated from scallion in suburbs of Nanjing where it had been applied with MBC and thiophanates for several years. Mycelial growth of this Rstrain was less inhibited on repaired PSA with 1000μg/ml MBC (technical samples) and the MIC value was hardly measured. Myceliaof the sensitive strains of B.cinerea that were isolated from scallion, plum, strawherry, cabbage, however, can not grow on the PSA containing 0.5μg/ml carbendazim. The MBC-resistant(R) strain was also resistant to benomyl and thiophanate on agar as compared with MBC-sensitive(S) strains. The MBC-R strain, however, and MBC-S strain are similarly sensitive to captan, chlorothalonil, and procymidone in vitro.The MBC-resistance of B. cinerea can be maintained at least fourty weeks on the biocide-free agar by continuous incubating.

从大葱上分离到的B1茵株(Botrytis cinerea)对多菌灵、托布津类杀菌剂有高度耐药性。在含多菌灵1000微克/毫升的马铃薯蔗糖琼脂(PSA)培养基上,该菌株的菌丝生长很少受到抑制,难以测定最低抑制浓度(MIC)值,而野生敏感菌株在0.5微克/毫升多菌灵浓度下,菌丝则完全不能生长。B1菌株对多菌灵、托布津、苯菌灵有高度交互抗性,但对克菌丹、百菌清、二甲菌核利杀菌剂的反应与野生型菌株相似。 B1菌株在无药的PSA培养基上菌丝转移连续培养12代后测定,只表现生长速率有所减慢,而对多菌灵的抗性程度无下降。
