몇몇 허브식물의 생육에 미치는 B-9과 Uniconazole 처리효과

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

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.

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.
