이연구에서재식밀도, 적심, 그리고예취가생육과수 량에 영향을 미쳤다. 재식거리 90cm × 30cm에서 최고 의생장과 수량을얻었는데, 이재식거리에서는최고초 장이 140cm, 식물체당 1차, 2차 및 3차 분지수가 각각 32개, 164개및 367개로자랐다. 이처리에서건조한꽃 의무게는 10a당 98kg에달해재식거리 120cm × 30cm 에비해 40% 증수되었다. 경경, 지상부 건물중및건조 한 꽃 무게는 적심 하였을 때 무적심에 비해 증가되었 다. 7월 10일 적심시 건조한꽃 무게가 10a당 102kg으 로무적심에 비해 57% 증가되었다. 생육과 수량특성은 무예취와 6월 10일예취처리간에비슷하였지만 7월 10 일예취에서는초장, 경경및분지수가무처리에비해유 의하게감소되었다. 누적 지상부 건물중은모든처리에 서차이가없었지만 6월 10일예취시건조한꽃무게와 꽃수가 10a당각각 123kg과 2,592개로가장많았다.
In this experiment, growth and yield were affected by planting density, pinching and mowing dates. The greatest growth and yield were obtained at a planting density of 90 cm × 30 cm. In this planting density, plant grew to the height of 140 cm, with 32 primary, 164 secondary, and 367 tertiary branches per plant. Weight of dry flowers reached 98 kg per 10a with this planting density, which was 40% increased as compared to planting density of 120 cm × 30 cm. Stem diameter, shoot dry weight, and weight of dry flowers increased by pinching plants as compared to those of non-pinched plants. The greatest weight of dry flowers was obtained in the plant pinched on July 10 with 102 kg per 10a, a 57% increase as compared to the control. Growth and yield were similar for both palnts which were not mowed and mowed on June 10. However, plants mowed on July 10 had significantly smaller plant height, stem diameter and number of branches than the control. An accumulated shoot dry weight was similar for all mowing treatments. The greatest weight of dry flowers and number of flowers per plant were obtained in June 10 mowing treatment with 123 kg and 2,592 flowers per 10a, respectively.
