Book Description
The second part deals with the relationships between environment and infection. Resting spores germinated more rapidly if dried and apparently only in the presence of host roots. In air-dry soil resting spores survived 56 days at -24°C. Minimum, optimum and maximum temperatures for infection of roothairs were below 11°, 14°- 20°, and 22°-25°, respectively. Between pH values of 5.2 and 7.5, soil pH had hardly any influence on invasion of root-hairs. At 16° to 20° the incubation period for tuber and root infection was less than 3 weeks.
