초록
생장억제제인 uniconazole의 토양관주 처리가 포인세티아의 생육 및 개화에 미치는 영향을 조사하여 포인세티아 재배시 적절한 uniconazole의 적절한 처리량과 처리시기를 제시하고자 시험을 수행한 결과, uniconazole의 토양관주시 초장, 분지장, 엽면적은 처리농도가 높아질수록 억제효과도 커지는 경향을 보였으며 0.05-0.10mg/pot 처리범위에서 적절한 효과를 보였다. Unionazole의 토양관주 처리시기가 이를수록 초장, 분지장, 엽면적이 크게 단축되었으며 모든 처리구에서 uniconazole처리에 따른 특징적인 약해는 관측되지 않았다.
This experiment was conducted to investigate the effects of uniconazole drench treatment on the growth and flowering of poinsettia and to suggest proper application dosage and time. Plant height, branch length, and leaf area were significantly restricted as the concentration of uniconazole increased. Application doses of 0.05 and 0.10 mg/pot effectively controlled the growth of poinsettia 'V-10 Amy'. Earlier soil drench of uniconazole resulted in more effective reduction in plant height, branch length, and leaf area. In all cases, no noticeable phytotoxicity by plant growth retardants tested was observed.
