STUDIES OF THE APPEARANCE OF NECROSIS IN RICE

수도의 Necrosis 출현에 관한 연구

This experiment was designed to get some information on the parts in which necrosis occurs first in the embryo of rice, and on the phenomenon of necrosis that develops into other parts. Norin No.6 harvested in 1967 was used for this experiment and necrosis appearance was investigated by the T.T.C. method. The results obtained are summarized as follows; 1) Necrosis of the embryo in rice occurred in the plumule initially. 2) It was observed that the necrosis developed from the plumule to the radicle. 3) Finally, it was shown that necrosis developed from the surface tissue of the embryo to the inside tissue.

벼종자에 있어서 necrosis가 어떤 부위에 어떻게 발현 되는가를 알기 위하여 1967년도산 농림육호 종자의 배를 추출하여 T.T.C.방법에 의거 관찰조사한 결과는 다음과 같다. 1) 발아부위에서 necrosisgus상이 처음 발생하였다 2) 유아부위에서 유근부위로 necrosis 현상이 점차 확대되어 가는 것을 알수있었다. 3) 배의 표면조직에서 내부조직으로 necrosisgus상이 이행되어 감을 볼수있었다.
