ジャガイモシストセンチュウのジャガイモ塊茎への寄生

抄録

Potato plants (“Benimaru”) grown in chloropicrin-treated soil in Wagner pots were inoculated with eggs and larvae of Heterodera rostochiensis. The green parts were cut off 72 days after inoculation. The tubers were harvested about 1 month later and examined under a dissection microscope. Considerable numbers of female and various stages of cysts were observed on or just beneath the surface of those tubers which had received a high level of the inoculum. Most nematodes were found at the eye part which involved primordial buds, and a few were on the smooth surface of the tubers.
