초록
수도품종(水稻品種)의 내냉성(耐冷性)을 실험실내(實驗室內)에서 화학적(化學的)인 분석방법(分析方法)에 의하여 조사(調査)하기 위하여 백화묘(白化苗) 및 유묘(幼苗)와 생육시기별(生育時期別) 잎 및 유수의 mitochondria 호흡활성(呼吸活性) 전이온도(轉移溫度)를 측정(測定)하고 내냉성정도(耐冷性程度)와의 관계(關係)를 검토(檢討)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 수도(水稻) 백화묘(白化苗)(
To evaluate cold tolerance of rice cultivars on the basis of a relationship between cold tolerance in the field test and a biochemical character, transition-temperature of respiratory activity of mitochondria(TRM) which were isolated from different parts and at different growth stages and from etiolated rice seedling was investigated, and its relationship with degree of cold tolerance(DCT) in the field experiment was studied. The results obtained were summarized as follows. 1. The transition-temperature of respiratory activity of mitochodria (TRM) isolated from etiolated seedling (
