The study was conducted to establish a method for the proliferation of hybrid poplar (P. alba × P. glandulosa) clone Bongwha1, an excellent biomass species. It was found that to collect the cuttings of Bonghwa1, it was necessary to use the main stem rather than the axillary branch. Stem growth by green-wood cuttings showed a tendency to decrease as the length of the collected cuttings increased, but the survival rate was low. Therefore, modified leafy stem cutting was attempted to increase the survival rate of the cuttings. In the modified leafy stem cutting method, 4 leaves were included in the cuttings, and especially, cuttings were performed using cuttings containing 2-4 cm xylem parts. Leafy stem cutting increased root growth and the number of stems, as well as the survival rate of hybrid poplar clone Bongwha1 compared to green-wood cuttings. The root growth of the leafy stem cutting poplar was better as there was more xylem part. Using two-year-old nursery stocks, the leafy stem cutting was used to produce about 66 cuttings. This study is expected to contribute to the mass propagation of high-quality nursery stocks.

간척성토지에서 SCBLF 처리효과를 알아보기 위하여 80일 동안 SCBLF 처리 후 포플러의 클론별 생육특성을 조사하였다. 엽면적은 SCBLF 처리구가 대조구에 비해 26% 증가하였다(P<0.05). 엽록소 함량은 처리구가 대조구보다 5% 증가하였으나 유의성은 없었다. 엽면적의 경우 Suwon, Clivus, 72-30, Dorskamp, 97-19서 처리구와 대조구간 통계적 차이가 있었고 (P<0.05), 엽록소 함량은 97-19에서 유의성을 나타났다(P<0.01). 잎의 T-N함량은 P<0.01에서 유의성이 인정되었으며, 클론별로는 97-19, I-476, Suwon, 72-30이 P<0.05, Clivus가 P<0.01 수준에서 유의성을 보였다. 수고 및 흉고직경 생장은 SCBLF 처리구가 대조구에 비해 각각 20%, 41% 증가하였으며 유의성이 인정되었다(P<0.01). 수고생장은 Clivus, 72-30, Suwon에서(P<0.05) 흉고직경생장은 Clivus, Eco28, Dorskamp,72-30, 72-31에서 유의성이 인정되었다(P<0.01). 특히 현사시(Clivus, 72-30)의 경우 잎의 엽면적, T-N함량, 수고 및 흉고직경 생장에서 통계적으로 유의한 차이를 보였으며 SCBLF 처리구가 대조구보다 높거나 우수하였다.
