Abstract

To investigate the relationship between symptom development of Bakanae disease and yield component (the length of panicle, weight of panicle, number of healthy grain per panicle and number of panicle per hill), rice seedlings infected with F. moniliforme were transplanted. The number of panicles per hill and healthy grain per panicle were greatly decreased by the development of Bakanae symptom. Yield components was not correlated with the time of the Bakanae symptom development. Rice plants with Bakanae symptom had lower yield as 210g per 10 hills than healthy plants as 469g per 10 hills.

Fusarium monilifome에 이병(罹病)된 유묘(幼苗)를 이앙(移秧)한 후(後) 키다리병병징출현주(病病徵出現株)의 수량구성요소(收量構成要素)를 조사(調査)하여 수량(收量)과의 관계(關係)를 보면 주당수수(株當穗數)와 수당건전입수(穗當健全粒數)순으로 수량(收量)에 영향(影響)을 주었다. 본답(本畓)에서 병징(病徵)이 나타내는 시기(時期)와 수량구성요소(收量構成要素)들 간(間)에 은일(一) 정(定)한 경향(傾向)을 보이지 않고 건전주(健全株)를 이앙(移秧)한 주(株)에서 무병징주(無病徵株)보다 수량(收量)이 증가(增加)하였다.
