Abstract

This experiments were conducted to investigate growth regulator concentrations and a period of chilling treatment for increasing the size of bulblets of Narcissus pseudo-narcissus cv King Alfred. Combination of 2.5 mg/L BA and 2.5 mg/L NAA remarkedly increased the diameter and growth of regenerated bulblets. Chilling period favorable for the growth of regenerated bulblets was found to be 8 weeks, and addition of 1.0 mg/L NAA alone to MS medium was the most effective for increasing the size of bulblet for the culture after the chilling treatment.

나팔수선 킹알프레드의 화경배양에서 얻은 대량의 소자구를 비대시키기에 적합한 호르몬 농도, 저온처리기간, 저온 처리 후 구비대에 적합한 호르몬 농도를 구명코자 하였다. 분화된 식물체의 구비대 및 생육은 BA 2.5mg/L에 NAA 2.5mg/L이 첨가된 MS배지에서 높았다. 자구비대를 위한 저온처리 기간은 8주간이 좋았으며 저온처리후 배양은 NAA 1mg/L가 첨가된 배지가 구비대에 가장 효과적이었다.
