벼뿌리선충의 벼뿌리갈변에 미치는 영향을 알아보기 위하여 벼가 자라는 배지조건을 달리하여 실내시험한 결과, 살균배지조건에서는 선충에 의하여 갈변도가 약간 높아졌으나 무살균조건에서는 선충의 존재여부에 관계없이 뿌리전체가 갈변되었는데 이것은 벼뿌리의갈변이 선충에 의한 다기보다 주로 그외의 토양미생물에 의하여 일어나는 것으로 보인다.

An experiment was carried out to know bow the rice root nematode, Hirschmanniella cryzae affects the root browning of rice pant growing in various combinations of media. In sterilized conditions of growing media, the root browning of rice plant was slightly promoted by the presence of the rice root nematode, while the entire roots were stained to brown in nonsterilized conditions of growing media. It seems that the root browning is due mainly to soil micro-organisms other than nematode which promotes it slightly under sterilized conditions.
