Abstract

This study was conducted to investigate the possibility of treating plant growth retardants to seeds to suppress height of plug seedlings. Seeds of ‘Hyangchon’ and ‘Nokkwang’ peppers were soaked in a 15 mL solution of either daminozide (10, 100, or 1,000 $mgáL^{-1}$), uniconazole (1, 10, or 100 $mgáL^{-1}$), or ethephon (1,000, 2,000, or 3,000 $mgáL^{-1}$) for one, three, and five days, respectively. Only uniconazole had significant effect on suppressing hypocotyl length and seedling height, while other treatments had decreased percent emergence without any expected suppression of stem length in both cultivars.

본 실험은 고추 플러그묘의 초장억제를 위하여 종자에 식물생장억제제의 처리 가능성을 조사하였다. ‘녹광’과 ‘향촌’ 고추 종자를 daminozide(10, 100, or 1,000mg·L-1), uniconazole(1, 10, or 100mg·L-1), 혹은 ethephon(1,000, 2,000, or 3,000mg·L-1)에 각각 증류수 15mL 첨가하여 1일, 3일, 또는 5일 동안 침지하였다. Daminozide 1,000mg·L-1에 3일 또는 5일, 그리고 ethephon 2,000mg·L-1과 3,000mg·L-1에 5일 처리구를 제외한 다른 처리구의 유묘출현율은 ‘녹광’ 고추에서 90% 이상을 나타내었다. Daminozide와 ethephon의 침지처리시 고추 플러그묘의 하배축 길이와 초장억제에 대한 효과는 낮았다. 하지만, uniconazole의 침지처리는 하배축 길이와 초장억제에 현저한 효과를 나타내었다. 품종간에 uniconazole에 대한 반응의 차이가 나타났고, 발아율과 유묘출현율이 낮아지는 나쁜 영향을 미쳤다.
