使小麦产生矮腥黑穗的技术试验,揭示出几种能产生高比例的侵染方法。其中多数方法是把Tilletia contro versa萌发的孢子放在种子上与之接触,然后使种子在控制的温度下萌发。有时把萌发的孢子施用到麦苗上,然后把苗保持在一定的温度下,侵染就发生了。初秋浅播后,在土壤上喷布孢子,使感病的小麦品种产生均匀的高比例的矮腥黑穗病。 A technical test that produces short, tangy black ears in wheat reveals several ways to produce high rates of infection. Most of these methods involve placing spores germinated with Tilletia controides on the seeds and then allowing the seeds to germinate at the controlled temperature. Sometimes the germination of spores applied to wheat seedlings, and then keep the seedlings at a certain temperature, the infection took place. After the early autumn sowing, the spores are sprayed on the soil so that the susceptible wheat varieties produce a uniform high proportion of dwarfed smut.
