Abstract

This study was conducted to stable direct sowing cultivation with seedling growth promotion by plant growth regulator treatment in onion seed(Allium cepa L.) The emergence percentage of soaked seed in BA, GA$_3$, and kinetin solution were higher than control seed, and those were 93.0, 94.3, 93.8%, respectively. The plant height was significant elongation in growth regulators treated seed, and those effects were high GA$_3$, kinetin and BA in the order, and the extend were high as increasing the growth regulator solution concentration in GA$_3$ and BA, and that was reverse in kinetin. The No. of leaf was increased in growth regulators treated seed, and the extend were similar among the growth regulators. The No. of root was increased significantly in growth regulators treated seed, and the extend were high in GA$_3$, BA and kinetin in the order.

양파의 직파재배를 안정화를 기하기 위한 일환으로 농도별로 조정한 생장조정제에 종자를 침지한 다음 포장에 파종하여 유묘의 초기생장성을 조사하였던 결과를 요약하면 다음과 같다. 1 식물생장조정제 처리 종자의 출아율은 BA, GA$_3$ 및 kinetin 이 각각 93.0, 94.3, 93.8%로 생장조정제별 차이가 거의 없었으나, 무처리 종자 80%보다는 훨씬 높았다. 2. 초장은 식물생장조정제 처리효과가 뚜렷하였는데, 그 정도는 GA$_3$, kinetin 및 BA순이었으며, GA$_3$,와 BA는 처리농도가 높을수록 초장이 컸던 반면, kinetin은 오히려 작아졌다. 3. 전개엽수는 식물생장조정제처리에 의해서 증가하였는데 식물생장제별 큰 차이는 없었다. 4. 유묘의 뿌리수는 식물생장조정제처리에 의해 뚜렷하게 증가하였는데. CA$_3$처리에서 가장 효과가 컸으며. 다음이 BA, kinetin 순이었다.
