Abstract
A Penicillium urticae Bainer, isolated from subsurface-tilled plots showing reduced wheat growth, produced a phytotoxic substance. The melting point and infrared and ultraviolet spectra of the crystalline material showed this substance to be patulin. Wheat shoot growth inhibition of 50 percent required 20, 20, and 75 parts per million of patulin in solution, sand, and soil culture, respectively.
摘要
从表土耕翻的麦田中分离到的一株荨麻青霉（Penicillium urticae Bainer），能产生一种使小麦生长受抑的物质。这种结晶物质的熔点、红外和紫外光谱表明它是棒曲霉素。棒曲霉素在溶液、沙和土壤培养中使麦苗生长抑制 50%时的含量分别为 20、20 和 75 微克/毫升。
