A sweet sorghum [Sorghum bicolor (L.) Moench] cultivar was planted on 9 and 30 June 2000 at plant densities of 4, 6, 8, 10, and 12 plants m-2 to determine the optimum plant density in Jeju region. There were no significant planting date x plant density interactions for most traits measured. Delaying planting from 9 to 30 June delayed 21 days in heading date, and significantly decreased plant height, the number of productive stems m-2 /, and lodging. Fresh stem yield tended to be higher at the 9 June planting date than at the 30 June planting date, but total sugar and ethanol yields were not significantly affected by planting date. Percentage of soluble solid was higher at the 30 June planting date compared with the 9 June planting date. Fresh stem, total sugar, and ethanol yields quadractically increased from 22.9 to 36.7 t-1 , from 1.66 to 2.54 t-1 , and from 945 to 1440 L-1 , respectively, with increasing plant density. The optimal plant densities for the maximum fresh stem, total sugar, and ethanol were estimated to be 10.7, 9.6, and 9.9 plants m-2 respectively.

최근 생활수준의 향상과 보건에 대한 관심의 증가로 약용식물 재배와 한약에 대한 연구가 증가되고 있다. 그러나 대량번식을 위한 종자번식에 있어서 많은 문제점을 안고 있다. 특히 산형과 약용식물에 있어서 시호(Bupleurum falcatum)나 회향(Foeniculum vulgare)은 발아율을 증가시키는데 있어서 만족할만한 발아율을 얻지 못하고 있기 때문에 본 연구를 수행하였다. 회향은 60%의 발아율은 나타내며 15, 20, 25, 15~20℃ 의 발아온도 처리간의 별다른 차이가 없었다. 호르몬 처리나 물리화학적 처리에서도 발아를 증진시킬 수 없었다. 이러한 발아불량의 원인은 시호에서와 같이 결국 무배종자가 많은 것으로 추정된다. 해부현미경과 주사현미경으로 종자의 배와 주공을 관찰한 결과 배가 있는 것과 없는 것의 비율이 1/1이며 주공자체내에는 문제가 없었다. Y자형과 일자(一字)형의 배를 가진 종자가 동시에 관찰되었다
