Abstract
본 실험은 상추의 춘파재배 시 종자의 건열처리 및 저온 처리에 따른 상추품종의 반응을 조사하고자 수행하였다. 추대반응은 저온처리, 무처리 및 건열처리 순으로 빨랐다. 초장은 저온처리에 의해 5-10 cm 가량 더 커졌으나 건열처리는 몇몇 품종의 경우 오히려 생육을 억제하였다. 건열처리와 저온처리의 차이는 정식 후 시간이 경과함에 따라 점차 상쇄되었다. 생체중은 모든 처리구간의 차이가 뚜렷하지 않았다. 'Red Gyeolku'는 매우 빠른 추대성을 나타내었으며 특히 저온처리에 의해 초장의 생육이 촉진되었다. 그러나 'Cheongchima'는 다양한 종자처리 이후에도 추대율이 높지않아 만추대성 품종으로 여겨졌다. A series of experiments were performed to evaluate effects of lettuce seed treatment with low temperature and dry heat treatment (DHT) on bolting response in the case of spring cultivation. During spring production in greenhouse, bolting response of the plants produced from the treated seeds was faster in the order of low temperature treatment, control and DHT. Plant height was increased 5-10 cm higher by low temperature treatment, but plant growth of some cultivars was inhibited by DHT. Difference on lettuce plant growth between low temperature treatment and DHT was gradually diminished with the lapse of time after transplanting. Fresh weight of plant was not significantly different among all treatments. 'Red Gyeolku' showed very early bolting response and plant height was significantly promoted by low temperature treatment. However, 'Cheongchima' showed low bolting percentage after various seed treatments, so it is considered late-bolting cultivar.
