桑树灰霉病菌Botrytis cinerea Pers.的生物学特性

桑树灰霉病(BOt尽tis‘i“leo Pers.)是桑树叶部病害,泽田兼吉(1919)虽曾在《台-湾产菌类调查报告》的灰霉菌(Bot摺ti:‘f秘lea)寄主目录中曾提到寄生于桑树,但在桑树上的其他方面的情况没有介绍,浙江省自1982年在本校桑园发现该病以来,1983年春在校园_桑树上发生已较普遍,有些品种甚至相当严重。现在我省其他地区也有发现,有的桑园被害相当严重,如1984年9月下旬笔者在海宁县调查的一片近百亩的桑园,株发病率达70%以上,以致桑叶产量锐减。 为了解决此病的防治问题,我们从1983年开始研究关于此病的症状描述、病原分离培养、品种感病性考查及室内药效测定等。1 984年曾报道对桑霉病的初步调查【‘]o本文则着-重介绍病原菌生物学特性方面的研究结果,期望在明确发生规律的基础上提高防治效果。一、材料与方法 (一)病原菌在不同培养基上的生长情况 从病叶分离得纯病原菌在P DA培养基上培养6天后,用无菌打孔器对匀质菌...  (本文共5页) 阅读全文>>

Identification of Damage on Different Plants Caused by Botrytis cinerea and its Extracellular Macromolecular Toxin

Botrytis cinerea is the pathogen of gray mold,causing dama-ging in many economic crops such as flowers,fruits and vegeta-bles.The pathogen has wide host range,and 235 species of hostshave been reported[1].Survey indicates that due to the damage ofB.cinerea,tomato yield is reduced by 20%to 40%and cucum-ber yield is reduced by 30%to 50%;strawberry yield is generallyreduced by 10%-30%,and the loss will reach about 50%un...  (本文共4页) 阅读全文>>

Triggering the biocontrol of Botrytis cinerea by Trichoderma harzianum through inhibition of pathogenicity and virulence related proteins

1 IntroductionSolanum esculentum,although technically a fruit,is one ofthe most economically important vegetable fruit cultivatedworldwide.However,its productivity is substantiallydecreased by gray mold,foliar diseases,root rots andwilts by several phytopathogens[1–3].The key phytopatho-gens belong to the genera Botrytis,Fusarium,Macro-phomina,Phytophthora,Rhizoctonia and Sclerotinia[4].Ofthese,Botrytis is particular...  (本文共9页) 阅读全文>>

Effects of different LED light wavelengths on the resistance of tomato against Botrytis cinerea and the corresponding physiological mechanisms

1.IntroductionGray mold caused by Botrytis cinerea,which is an airborne plant pathogen,is one of the serious diseases that harms over 200 types of crops worldwide(Williamson et al.2007).As one of the major greenhouse vegetable crops throughout the world,the tomato is also seriously affected by this disease,especially in improper ventilation greenhouses.B.cinerea usually primarily infects tomato leaves,and then stems ...  (本文共9页) 阅读全文>>

Hot air treatment activates defense responses and induces resistance against Botrytis cinerea in strawberry fruit

1.IntroductionStrawberry fruit is highly perishable and susceptible topathogical decay at ambient temperature storage.Graymold caused by Botrytis cinerea(B.cinerea)is one of themajor postharvest disease that limits the storage life ofstrawberry fruit(Civello et al.1997).Traditionally,fungicideshas been used to reduce postharvest decay of strawberryfruit.However,consumers concern over potentially harmfuleffects on the...  (本文共8页) 阅读全文>>
