内容 各種の草本, 木本植物に対するCristulariella pyramidalis(環紋葉枯病菌)の寄生性とその病徴の特徴について記述した.供試した45種の草本植物のうち, 無傷接種で24種, 有傷接種で41種に対して寄生性が認められた.また104種の木本植物のうち, 無傷接種で18種, 有傷接種で101種のものに寄生性が認められた.感受性の顕著な植物は, 草本, 木本植物ともさまざまな科, 属にわたり, 特定の傾向はなかった.また同一属の間でも種によって菌に対する感受性に明瞭な差異が見られた.接種植物における病徴の特徴は感受性のいちじるしい草本植物では水浸状の軟腐を呈するものが多かった.木本植物では, 輪紋, 落葉, 葉脈黒変, 穿孔, 水浸状ハローなど多様な症状を呈した.中でも本菌に固有な輪紋症状はバラ科など多くの植物に現われた.また, 落葉性の症状は, つる性植物や複葉形態の植物でとくに激しく認められた.病斑上でsporophoresを形成したものは, 供試植物のうち比較的少数にすぎなかったが, 菌核形成は多数のものに認められた.
Parasitic ability to various herbaceous or woody plants of Cristulariella pyramidalis and nature of symptoms in inoculated plants. K. HIRANO, W. IIDA and N. USHIYAMA Faculty of Horticulture, Chiba University, Matsudo, Japan. Tech. Bull. Fac. Hort. Chiba Univ., No.25: 71-81, 1977. The authors demonstrated on the parasitic ability to the herbaceous or woody plants of one hundred and forty nine species inoculated with Cristulariella pyramidalis WATERMAN and MARSHALL. Among forty five herbaceous species tested, symptoms on the leaves developed in plants of twenty four species under the mycelial inoculation without wound, and those of forty one species occurred symptoms only when the leaves were wounded. Among the woody plants of one hundred and four species tested, symptoms developed in plants of one hundred and two species under the wound inoculation. However, when the leaves were not wounded, symptoms developed in plants only eighteen species. The kinds of susceptible plant to C. pyramidalis among the test materails were widely established into the various families or genera both the herbaceous or woody plants, and in some cases the susceptibility differed between the species in the plants of same genus. Symptoms of the herbaceous plants showing severely susceptible were characterized a water soaked and soft rot development in the moist chamber. In the woody plants, symptoms varied such as concentric ring formation, defoliation, vein necrosis, shot hole and water soaked halo in the different species. Concentric ring formations characteristically known as the symptom by C. pyramidalis were pronounced in many species of the test materials, particularly include Rosaceae. Defoliation was typical nature of the symptom in the liane or the plants forming compound leaf. Sporophores were observed on the infected leaves in some materials restrictedly and sclerotia were produced frequently in more species.
