Abstract

This experiment was carried out to investigate the effect of subirrigation of Dolrido on the growth and development of stem cutting and young roes plant. Plant growth was measured at 20, 40, and 60 days after subirrigation of Dolrido. Plant height, stem diameter, number of leaves, leaf area and root length of cutting rose subirrigation were more affected than those of control. The growth of young seedling was significantly affected by subirrigation of Dolrido. Plant height, number of leaves, stem diameter, leaf area, fresh and dry weight were increased with subirrigation of Dolrido. However, T/R ratio was not affected by subirrigation of Dolrido. Growth of seedlings was promoted after 60 days treatment of Dolrido.

장미 삽목묘에 돌리도를 주기적으로 관주하여 초장, 경직경, 엽수, 엽면적, 최대 근장 등 생육반응을 검정한 결과 돌리도의 관주처리는 삽목묘의 초기생육에 큰 차이는 없었으나 60일 후의 후기생육은 향상되었다. 장미 유목에 돌리도를 관주 처리하면 초장, 경직경의 향상과 줄기의 부피생장 더불어 엽수 및 엽면적이 증가되었다. 돌리도를 주기적으로 관주한 장미유목은 이를 처리하지 않은 대조구에 비해 초장이 6.4∼11.0 cm, 경직경은 0.70∼l.14 cm증가하였고, 엽면적도 $136cm^2$ 높았다. 또한 돌리도의 처리에 의해 총 생체중 및 총 건물중을 증가시켰는데, 그 효과는 생육후기로 갈수록 현저하였다.
