  • In recent years increasing production and disposal of wastewater have caused an accelerated eutrophication of receiving waters. Therefore, in order to alleviate the detrimental impact of wastewater discharge, there is an increasing demand for removing the main nutrients, nitrogen and phosphorus, as well as the organic content of the waste water prior to disposal. This is effectively achieved by extended conventional treatment technology. However, the working expenses and energy requirements of such advanced treatment systems are rather high. So in a sparsely populated rural community is required development of wastewater treatment system combined with the regional characteristics. In this study, the systems are planted with Reeds and Amaryllis In A.C and estimated purification potential of system. The results obtained are as follows. BOD removal rate is 20% in the early stage, the last removal rate is 35% in A.C process and is 65% in Amaryllis+A.C process and is 50% in Reed+A.C process. T-N removal rate by Amaryllis is average 2.6g/$m^3$ㆍd, T-N removal rate by Reed is average 1.76g/$m^3$ㆍd. T-P removal rate by Amaryllis is average 0.27g/$m^3$ㆍd, T-P removal rate by Reed is average 0.25g/$m^3$ㆍd. BOD removal rate constant with retention time is 1.4494(1/d), T-N removal rate constant is 0.5428(1/d), T-P removal rate constant is 0.5287(1/d).

  • Amaryllis ($Hippeastrum{\times}johnsonii$) is commonly propagated by three methods: seeds, offset bulblets, and twin scaling. Since the number and size of bulblets produced by these methods are low, we conducted an experiment to evaluate different bulb cutting methods for propagation. For this purpose, bulbs (circumference of 30 - 35 cm) were sectioned or notched into 8, 12, or 16 segments or twin-scaled into 48, 72, or 96 segments for bulblet formation. Our results show that the largest number of bulblets was produced by the twin scaling method, but they take longer to grow to a final, commercial size. Sectioning and notching resulted in larger, but fewer bulblets than twin-scaling. Compared to notching, sectioning provided more space for the bulblets to grow, and is therefore the recommended method. While increasing the number of sections cut from a single bulb resulted in a larger number of bulblets, the diameter of the bulblets decreased. Therefore, sectioning the bulb into 8 segments was the best method for producing an acceptable number of vigorous bulblets.

  • 아마릴리스 'Picottee', 'White Christmas', 'Eldorado', 'Origin', Red Lion', 'Telstar', 'Crypsy'의 교잡배를 여러 농도의 2,4-D, NAA, BA, TDZ가 첨가된 MS배지에 배양한 결과, 0.5~3.0 ㎎/L 2,4-D에 비하여 0.5~3.0 ㎎/L NAA 처리구에서 줄기와 자구 분화가 양호하였다. 0.5㎎/L NAA 처리는 배양체로부터 높은 자구 형성율을 나타냈고, 줄기 분화율은 NAA 1.0㎎/L과 TDZ 2.0㎎/L 혼용처리구에서는 가장 높았다. 배지에 1.0~2.0㎎/L TDZ 첨가는 치상체당 더 많은 줄기를 분화시켰으나 1.0~2.0㎎/L BA 처리보다 뿌리의 발달은 억제되었다. 'Star Van Holland'의 인편을 배양했을 때 자구 형성은 0.5㎎/L NAA가 첨가된 배지에서 가장 효과적이었다.
