Abstract
The effect of Milliwrap and Uniwrap attached to the lid on the growth and acclimation of lily growing in vitro was investigated. Milliwrap treatment increased the plant height 1.6 and 1.2 times higher than control in 'Dame Blanche' and '94-36', respectively, plant height of 'Dame Blanche' was 6.1㎝ and '94-36' line was 13.4 ㎝. Two treatments slightly inhibited the fresh weight in 'Dame Blanche', whereas Milliwrap and Uniwrap enhenced the fresh weight more than 30% in '94-36'. Leaf width (1.0 ㎝) of Milliwrap treatment was most wide, which was 2.5 times higher than that of control. In the fresh weight of bulblets, the fresh weight per bulblet of treatment was higher than control in '94-36', but the number of bulblets per scale were few in the treatment to control. In the air composition of culture vessel, ethylene content (0.03 ppm) was low in the Milliwrap treatment compared with the control. CO₂ content of control was higher than treatments as 0.11% and it was about 3 times to air condition of out side. The acclimation ratio of Milliwrap treatment was higher as 85.1% and control was similar with Uniwrap treatment.
백합 'Dame Blanche', 94-36' 조직배양시 배양용기 뚜껑에 Milliwrap및 시판용 Uniwrap을 부착한 통기처리가 생육 및 순화에 미치는 영향을 검토한 결과, 초장은 대조구에 비하여 Milliwrap처리구가 가장 컸고 'Dame Blanche'가 1.6배, ‘94-36'은 1.2배 였으며 생체중은 'Dame Blanche'의 경우 처리구가 대조구에 비하여 낮았고 ‘94-36'은 처리구가 대조구보다 30%이상 높았다. 엽폭도 Milliwrap처리구에서 가장 넓게 나타났으며 'Dame Blanche'의 경우 1.0㎝였고 대조구 0.4 ㎝에 비하여 2.5배 였다. 소인경의 경우 대조구에 비해 처리구가 형성수는 적었지만 ’94-36'의 경우 소인경 한 개의 무게는 처리구에서 더 무거웠다. 배양용기내 공기조성 중 ethylene은 Milliwrap처리구에서 0.03 ppm으로 가장 낮았고, 대조구가 0.32 ppm으로 가장 높았으며, 이산화탄소 함량도 대조구에서 0.11%로 가장 높았으며 이는 일반 공기 0.03%의 3배 정도였다. 순화율도 Milliwrap처리구에서 85.1%로 가장 높았으며 대조구와 Uniwrap처리구에서는 비슷하였다.
