Abstract

This study was carried out to investigate the effects of in vitro culture condition and among lines on growth pattern of lateral buds from nodal cuttings of Phalaenopsis flower stalks. The ratio of bud growing into shoot from nodal cuttings of flower stalks were 90.9% and 54.4% on MS and hyponex medium, respectively. The number of buds grown vegetatively were increased remarkably on the MS medium containing 5 mg/L BA. The rate of buds grown vegetatively was higher in basal and middle parts than in upper part of flower stalks. The flower stalk sections cultured at 25~28$^{\circ}C$ showed the highest ratio of vegetative growth. Medium contamination was decreased by pretreatment of etiolation to the flower stalk. However, the pretreatment did not show specific effects on shoot development and reduction of phenolic compound. Average shoot number which was formed from flower stalk segments in 27 of 30 accessions were 3.17, while high number of shoots were obtained from Phal. 3020 and Phal. 3039. The growth pattern of lateral buds in F$_1$hybrids was similar to that of their parents.

화경절 액아 유래 신초의 잎을 이용한 팔레높시스 대량번식에서 배양재료로 이용되는 신초의 발생수를 증가시키기 위해 화경배양을 위한 배지, 배양온도 화경 전처리 등 기내 배양조건과 계통 간 화경의 발육형태에 대해 조사하였다. 화경절 액아의 신초발생률은 MS배지에서 90.9%, Hyponex 배지에서 54.4%이었다. 5 mg/L의 BA가 첨가된 MS배지에서 신초가 많이 형성되었으며 발육상태도 양호하였다. 화경 액아의 위치별 발육형태는 기저부 쪽일수록 신초발생이, 상부 쪽일수록 2차화경이 많이 발생되었으며 25~28$^{\circ}C$의 배양온도는 액아로부터 신초를 얻는 데 적절하였으며, 황화처리는 오염률을 낮추는 데 효과가 있었으나 페놀물질 유출량의 감소효과는 없었다. 수집한 30계통 중 27계통의 화경에서 신초를 얻었으며 화경편 당 평균 신초수는 3.17개이었으나 Phal. 3020, 3039 등은 신초가 많이 발생되어 다른 계통과 차이가 있었다. 교잡 F$_1$계통의 화경발육 양상은 모본(수집계통)과 비슷하였다.
