摘要：

The effects of different daylengths (12 and 16 hr) on hatching, invasion of the host, and reproduction of different populations of potato cyst-nematodes on European potato plants, Solanum tuberosum ssp. tuberosum, were studied. Invasion and root weight were greater in plants grown in 16- than in 12-hr days. The ratio of male to female larvae of G. pallida hardly changed but the ratio of male to female G. rostochiensis larvae was greater in 16- than in 12-hr days. Populations of both species from Europe tended to produce more cysts on plants grown in 16-hr days, but G. rostochiensis from Peru produced more on plants grown in 12-hr days. Hatching from cysts produced in 16-hr days was also greater than from those produced in 12-hr days but no significant differences between activities of root diffusates produced in different daylengths were found. © 1979 BRILL.
