摘要
采用田间空中孢子捕捉方法证明稻曲病菌孢子在田间具有气流传播的能力。种子和土壤带菌不可能是田间的主要初侵染源，萌发的黑色厚垣孢子是主要的初侵染源。在稻田外可能有适合于稻曲病菌黑色厚垣孢子休眠，并能在翌年夏季打破休眠。
The air current dissemination funation of the spore of rice false smut, Ustilaginoidea virens (Cooke) Takahash, is confirmed by capturing air-bornetechnique. The germinated black chlamydospores are the major source of the primary infection source instead of both seed-borne and soil-borne in rice field. Other infection source or alternative hosts suitable for dormancy of the black chlamdospore and inducing its germination in next sammer may exist outside the paddy.
