Effect of B-9 and Uniconazole on the Growth of Mentha piperita, Origanum vulgare L., and Thymus vulgaris L.

몇몇 허브식물의 생육에 미치는 B-9과 Uniconazole 처리효과

The plant height and internodal length of Mentha piperita, Origanum vulgare L., and Thymus vulgaris L. were reduced according to the treatment of 500, 2,500, 5,000 mg/L B-9 and 0.5, 1.0, 5.0 mg/L uniconazole. On the efficiency of dwarfing in 3 herb species, uniconazole was more effective than B-9, but plant height of Thymus vulgaris was more shortened with 2,500mg/L B-9 treatment than 3 levels of uniconazole treatments. Cuttings from 3 kinds of herbs tested were died with 5,000mg/L B-9 treatment. The number of lateral shoots per plant was heighest at control plants and uniconazole was more effective in reducing lateral shoots than B-9. There was no significant difference in leaf growth between B-9. There was no significant difference in leaf growth between B-9 and uniconazole treatments. The root growth of Mentha poperita, Origanum vulare, and Thymus vulagris was not significantly affected by B-9 or uniconazole.

식물생장억제제 처리시 대조구에 비하여 초장이 짧아지는 것으로 나타났으며 uniconazole 처리가 B-9 처리보다 초장억제에 더욱 효과적이었으나 Thymus vulgaris 2,500mg/L B-9 처리시는 uniconazole 처리보다 초장이 짧은 결과를 보였다. 5,000mg/L B-9처리시 공시한 3종 모두의 삽수가 고사하였다. 신초수는 대조구에서 가장 많이 발생하였으며 B-9 처리시는 uniconazole 처리에 비하여 신초발생이 많았다. 잎에 대한 생장억제제의 처리 효과는 공시식물 모두 유의차가 적었으며 절간장은 초장과 같은 결과를 나타내었다. Mentha piperita, Origanum vulgare와 Thymus vulgaris 지하부 생육은 B-9이나 uniconazole에 의해 현저하게 영향 받지 않았다.
