中国におけるLeptosphaeria weimeri(=Longiseptatispora meliloti)によるアカクローバーの葉の斑点病
Leaf Spot Disease of Red Clover Caused by Leptosphaeria weimeri (=Longiseptatispora meliloti) in China
大菌輪-論文3行まとめ
中国甘粛省のアカクローバー畑で発見された葉の斑点病の病原菌を調査し、Leptosphaeria weimeriと同定した。
本種との同定は形態形質、病原性試験、および分子系統解析によって確かめられ、中国からの本種の報告は初となった。
生育適温は20°C、胞子形成温度は25°C、至適pHは7で、プロクロラズ殺菌剤がin vitroにおける最も有効な防除薬剤であった。

病害

サイズ
Root rot, crown rot, stem blight and leaf spot. In alfalfa the taproot, crown, branches, and leaves are affected. The leaf spots are circular to irregular, light buff to greyish-white, 2-10 mm wide, sometimes involving the entire leaflet, with or without concentric bands, but always with a reddish-brown border. Usually pycnidia occur in the paler central areas of the spots. The visible symptoms on roots are smooth dark brown to black lesions which later dry, crack and become roughened. Beneath the surface the tissues turn reddish-brown to almost black. As the disease progresses slowly a dry rot develops followed by the appearance in the bark of a reddish colour which extends into the decaying wood rays. No new buds are formed and the plant eventually dies (18, 320). On species of Melilotus leaf spots have been reported as abundant in early spring and late in the fall in the U.S.A. In one variety of sweet clover only leaf spots have been reported abundant in the mid summer. The fungus enters roots through wounds. [1]

conidiomata on leaves

サイズ
circular, 30-35 µm wide, surrounded by darker cells [1]
composed of 2-4 layers of pseudoparenchymatic cells, outer layers yellowish-brown to brown, innermost layer lining the pycnidial cavity hyaline [1]

transmission

The fungus is probably soil-borne and survives in fodder crop debris. Conidia produced within pycnidia on leaves are liberated in masses when water is present and water splash helps dissemination. Entry into roots is through wounds (18, 320). [1]
