To examine the potency of biosorbent, the adsorption capacity of Pseudomonas cepacia H42 isolated from fresh water plant root was compared with Saccharomyces cerevisiae SEY2102 on bases of biomass, concentration of heavy metal, presence of light metals, immobilized cell, and ion exchange resin. P. cepacia H42 biomass of 0.05-0.5 g/L increased adsorption and above 1.0 g/L of yeast biomass was the most effective in adsorption. By applying the same amount of biomass, lead showed the highest adsorption on two strains and the adsorption strength was lead>copper>cadmium on both strains. The high heavy metal concentration induced the high adsorption capacity. P. cepacia H42 adsorption was in the order of copper>lead>cadmium and lead>copper>cadmium by yeast in 10 mg/L. Both strain showed same adsorption strength in the order of lead>copper>cadmium in 100 mg/L and 1000 mg/L. The adsorption capacity of both yeast and P. cepacia H42 was decreased in the presence of light metals and the order of cadmium>copper>lead. Mg 2+ induced the least adsorption while Na + induced highest adsorption. The adsorption capacity of immobilized yeast and P. cepacia H42 was detected between 200-400 mL in flow volume and decreased in the presence of light metals. Ion exchange containing light metals caused 30-50% adsorption reduction on both strains.

Actual evapotranspiration (AET) in the Suyeong-gu was estimated and correlations between AET and meteorological factors were analyzed. The study area was Suyeong-gu lay at the east longitude 129° 05′40″∼ 129° 08′08″ and north latitude 35° 07′59″∼ 35° 11′01″. The Kumryun mountain, the Bae mountain, the Suyeong river and the Suyeong bay are located on west, north, northeaster and south side in the study area, respectively. AET was estimated using precipitation (P), potential evapotranspiration (PET) and plant-available water coefficient. Meteorological factors to estimate PET were air temperature, dewpoint temperature, atmospheric pressure, duration of sunshine and mean wind speed (MWS). PET and AET were estimated by a method of Allen et al. (1998) and Zhang et al. (2001), respectively. PET was the highest value (564.45 mm/yr) in 2002 year, while it was the lowest value (449.95 mm/yr) in 2003 year. AET was estimated highest value (554.14 mm/yr) in 2002 year and lowest value (427.91 mm/yr) in 2003 year. Variations of PET and AET were similar. The linear regression function of AET as PET using monthly data was and coefficient of determination was high, 0.75. In order to analyze relationship between the evapotranspiration and meteorological factors, correlation analysis using monthly data were accomplished. Correlation coefficient of AET-PET was 0.96 high, but they of AET-P and PET-P were very low. Correlation coefficients of AET-MWS and PET-MWS were 0.67 and 0.73, respectively. Thus, correlation between evapotranspiration and MWS was the highest among meteorological factors in Suyong-gu. This means that meteorological factor to powerfully effect for the variation of evapotranspiration was MWS. The linear regression function of AET as MWS was and coefficient of determination was 0.54. The linear regression function of PET as MWS was and coefficient of determination was 0.45.

소맥의 파종심도에 따른 관부위치의 품종간 차리를 구명하여 조숙내한다수성 품종육성과 조숙품종의 한해방지를 목적으로 한국, 일본, 미국, 유럽 등지에서 도입된 50품종을 공시하여 작물시험장의 온냉사절온실에서 1976연에 실험한 결과를 요약하면 다음과 같다. 1. 파종심도별 평균 출현율은 일본, 유럽품종은 67∼69％이며 한국, 미국품종은 63∼64％이였고 파종심도가 깊을수록 출현율이 낮았으며 3cm 80％, 6cm 72％, 9cm 61％, 12cm 51％로 3cm씩 깊이 파종하므로서 10％의 출현율이 감소되었다. 2. 파종심도 9cm, 12cm구에서 70∼80％以上 발아하는 품종은 Benhur, Biserka, Expection, 밀양005, 밀양7호, NS 177, Sage 등이였으며 파종심도 6cm구에서 80％이상 발아하는 품종이 많았다. 3. 파종심도를 3cm로 하였을때 초엽장은 일본, 미국, 유럽, 한국품종 순으로 길었고 지중경형성률은 일본<유럽<한국<미국품종 순으로 적었으며 고엽율은 한국과 미국품종들이 적었다. 4. 파종심도에 따른 50품종의 평균 지중경장은 파종심도가 깊을수록 직선적으로 길어지며 관부읍치는 9cm파종구 까지는 다소 깊어지나 12cm파종구에서는 3cm구보다 관부위치가 오히려 얕아졌다. 5. 3∼9cm파종심도에서 도입국별 품종의 관부위치는 유럽<한국<일본<미국품종 순으로 길었다. 6. 3∼6cm파종심도에서 관부위치가 깊은 품종은 한국품종에서 조광, 원광, 남광, 수원20002, 밀양005, 밀양7호 등이며 영광, 장광, 진광은 매우 얕았다. 일본품종중에서 농림004, Kitagarnigoumgi, 중국8001, 미국품종중에서 Sage, Blueboy, Expection, Oasis, CI14034, Rossalka, Benhur, 유럽품종중에서 Biserka, Martonvasar-1, Martonvasar-2 등온 관부입치가 깊었다. 7. 파종심도 3cm, 6cm, 9cm ,12cm에서 관부위치 상호관의 상관은 정의 상관을 보이며 그중에서 6cm 파종구에서 상관이 가장 높았다. 8. 초엽장이 짧거나 지중경형성률이 낮은 것은 관부위치가 깊어지며 관부위치와 지중경장과는 고도의 부상관이 있었고 지중경장이 길어지면 관부위치가 얕아진다. 9. 출수기가 빠른 것은 관부위치가 깊어지는 정의 상관이 있고 고엽률과 관부위치와는 상관이 없으나 내한성이 강한 품종이 관부위치가 깊은 것이 있었다.
