KOREASCHOLAR

본 실험은 장미의 삽목시 증산억제제와 생장억제제를 활용 하여 미스트나 밀폐시설 없이 삽목발근 효율을 증가시킬 목적으로 수행하였다. 절화장미 ‘M-Red’ 줄기 삽목 후 증산억제제 ‘Wilt Pruf’ 및 ‘Cloud Cover’ 1, 2, 4, 8%와 생장억제제 paclobutrazole 10, 20, 40, 80mg･L-1, diniconazole 100, 200, 400, 800mg･L-1를 각각 엽면살포 하였다. 증산억제제의 효과 는 종류에 따라 달랐는데, Wilt Pruf는 생존율, 신초 발생율, 발근율을 모두 향상시켰으나 신초수, 뿌리수, 뿌리길이에는 영향을 미치지 않았다. Cloud Cover는 생존율과 발근율을 향상시키는 효과가 없었으나 신초 발생율이 처리농도와 비례하여 높아져 4, 8% 처리시 가장 높게 나타났다. 생장억제제 처리효과도 종류에 따라 달라 paclobutrazol은 생존율과 발근율 향상에 영향을 미치지 않았으나 신초 발생율을 높였으며 1% 처리시에 신초발생이 가장 높았다가 농도가 높아지면서 낮아졌다. Diniconazole은 100, 200mg･L-1 처리시 생존율과 발근율을 향상시켰으나 800mg･L-1의 고농도에서는 생존율과 발근율 모두 낮게 나타났다.

This experiment was conducted to increase the rooting efficiency of rose plants by using antitranspirants or plant growth retardants during the greenwood cutting propagation of roses without mist or closed facilities. After the insertion of the ‘M-Red’ cutting stem into the rooting media, antitranspirants (Wilt Pruf or Cloud Cover at 1%, 2%, 4%, 8%) and growth retardants (paclobutrazol 10, 20, 40, 80 mg･L-1 or diniconazole 100, 200, 400, 800 mg･L-1) were applied using the foliar spray method. The effect of the antitranspirants was dependent on the commercial products. Wilt Pruf improved the survival ratio, shooting ratio and rooting percentage of cuttings, but did not affect the number of shoots and roots, or the root length of rooted cuttings. Cloud Cover did not improve the survival and rooting ratio, but did increase the shooting ratio as the concentration increased, which was the highest at 4% and 8%. The effect of the growth retardants also varied dependent upon the commercial product used. Paclobutrazol did not affect the survival and rooting ratios, but increased the shooting ratio. The shooting ratio was highest in the 1% treatment, then decreased as the concentration increased. In contrast, diniconazole tended to improve the survival and rooting ratio when treated with 100 and 200 mg･L-1, but was lowest at the high concentration of 200 mg･L-1.
