This study was conducted to determine the effects of high temperature and deficit irrigation on growth and yield of hot pepper. Hot pepper was subjected to four irrigation treatments: fully irrigation (FI), 10, 20, and 30 days deficit irrigation (DI) combination with high temperature treatment. Control plants were grown natural environment and conventional culture methods. The plant height treated with high temperature was significantly higher than that of control plant. At FI combination with high temperature treatment, growth parameters such as stem diameter, leaf area, fresh and dry weight were the greatest. The yield was the greatest (2,036 kg/10a) under control, DI combination with high temperature treatment decreased by approximately 42% compare with FI combination with high temperature treatment. The number of abnormal fruits was approximately 38/plant under control, which was the smallest and that of 30 days DI combination with high temperature was higher 3.3 times compare with control. Flower abscission and calcium deficiency induced by DI treatments, especially those physiological disorder promoted by increasing DI treatments period. Results indicated that yield of hot pepper reduced by DI treatments, these results suggest that the growers should irrigate to proper soil moisture for preventing reduction of total fruit yield.

어린 싹을 길러 이용하는 채소에 대한 관심이 커지고 있어, 무 싹채소의 생육 증진과 유통 중 나타나는 영향을 검토하고자 CO₂처리 효과를 검토하였다. 본 실험에서는 재배 중 CO₂ 처리를 가스나 탄산수 형태로 하여, 생육뿐만 아니라 수확후 모의유통 중 포장 내의 생체중량 감소, 선도와 hue angle 등 수확후 변화 정도를 조사하였다. 재배 후 수확 시 생육에서 처리 여부에 따라서는 CO₂ 처리가 무처리보다 경장이 약간 길어지는 효과가 있었으며, 엽록소형광이나 SOD 값에서 무처리와 CO₂ 처리가 다소 다른 경향을 보였다. 그러나 CO₂ 처리 방법 간의 차이를 언급하기는 어려워 탄산가스 대신 탄산수 이용의 가능성을 보였다. 수확 후 포장 내의 CO₂ 처리로 인해 무 싹채소의 O₂ 소모가 크고 CO₂ 축적 정도가 다소 높아졌으며, 모의유통 중에 수확전 CO₂ 처리가 hue angle 값을 비롯하여 SPAD, 외관 등에서 낮은 수치를 보여주었다. 그러나 CO₂ 처리 방법 간에는 큰 차이를 보이지 않은 것으로 나타났다. 무 싹채소의 재배 중 CO₂ 처리에 의한 처리가 경경 등의 생육량을 증가시키나, 모의유통 시 수확후 선도 유지의 효과가 크지 않아, 재배 중 다른 방법을 통한 품질을 개선할 수 있도록 연구가 더 필요한 것으로 생각된다.

This study was designed to observe the effects of nutritional supplementation of general Korean diet on calcium metabolism and bone growth in rats. The results were summarized as follows. 1. The bone weight and the concentration of ash and calcium in femurs tended to be increased by calcium supplementation. It seemed that supplemental calcium feeding promoted bone calcification through increasing the amount of calcium retained in the body. 2. There were no differences in calcium absorption rates, retention rates in the body, urinary excretion, and serum calcium concentration, between calcium supplemented groups and the other cereal-vegetable groups. 3. The casein, vitamin B2, or vitamin A supplementation of cereal-vegetable diets did not have any significant effects on calcium metabolism and bone growth.

This study was conducted to investigate effects of waterlogging on the growth, physiological responses, and yield of Kimchi cabbage. The growth of Kimchi cabbage with applied optimized air temperature (set to $20^{\circ}C$) was greater than those with high air temperature (set to $30^{\circ}C$) and the growth significantly decreased by severe waterlogging treatment. The net photosynthetic rate of outer leaves on one hour after waterlogging treatment was higher at 72 hours waterlogging treatment in $20^{\circ}C$ and lower at 24 hours of waterlogging treatment in $30^{\circ}C$. The root activity was decreased by the elevation of waterlogging periods in $20^{\circ}C$ treatment and lower by the short of waterlogging periods in $30^{\circ}C$ treatment. The ratio of formality with non-waterlogging treatment was approximately 64% under $20^{\circ}C$ air temperature and that of range was from 16 to 30% under $30^{\circ}C$. The yield under $20^{\circ}C$ showed higher than that under high air temperature. The non-waterlogging treatment in $20^{\circ}C$ had 4,463 kg/10a, which was the greatest among all treatments, while yields of non-waterlogging treatment at $30^{\circ}C$ were significantly low as 1,082 kg/10a. Results suggested that additional drainage work should be needed to overcome waterlogged conditions of open field during heavy rainfall and should be drainage as soon as possible if there are waterlogging.

대목의 종류가 참외의 생장, 비대 및 품질에 미치는 영향을 검토한 결과는 다음과 같다. 참외 지상부의 생육은 자근묘에 비하여 접목묘에서 생육이 빨랐으며, 접목묘 중에서는 홍토좌 보다는 엘리트, 신토좌에서 우수하였으며, 초장, 엽수 등 생육은 정식 30일 후부터 급격한 신장을 보였다. 과장과 과폭의 비대속도는 대목종류간에는 큰 차이가 없었다. 과실의 품질을 조사한 결과 자근묘에 비하여 세력이 강한 엘리트, 신토좌접목묘에서 과중은 무거웠으나, 당토는 엘리트 접목묘 $12.5^{\circ}Brix$에 비하여 자근묘에서 $1.4^{\circ}Brix$ 더 높았다.

The recognition that omega-3 polyunsaturated fatty acids (n-3 PUFA) possess potent anti-inflammatory properties in human models has prompted studies investigating their efficacy for animal growth and immunity. This study examined the effect of feeding an n-3 PUFA-enriched diet on growth and immune response of weanling piglets. Newly weaned pigs (averaging $27{\pm}2$ days of age and $8.1{\pm}0.7kg$ of body weight) were assigned randomly to receive a control (3% vegetable oil, n = 20) or n-3 PUFA-supplemented (3% marine n-3 PUFA, n = 20) diet for 28 day after weaning. Female pigs consuming the n-3 PUFA-enriched diet were lighter at week 4 post-weaning than those fed the vegetable oil supplement. Weanling pigs gained more weight, consumed more feed and had better growth to feed ratios between days 14 and 28 than between days 0 and 14 post-weaning. Plasma insulin-like growth factor I (IGF-I) decreased between days 0 ($87.2{\pm}17.0ng/mL$) and 14 ($68.3{\pm}21.1ng/mL$) after weaning and then increased again by day 28 ($155.2{\pm}20.9ng/mL$). In piglets consuming the vegetable oil-enriched diet, plasma tumor necrosis factor alpha (TNF-${\alpha}$) increased from $37.6{\pm}14.5$ to $102.9{\pm}16.6pg/mL$ between days 0 and 14 post-weaning and remained high through day 28 ($99.0{\pm}17.2pg/mL$). The TNF-${\alpha}$ increase detected in the piglets fed vegetable oil was not observed in the piglets fed n-3 PUFA. Results indicate that weaning induces considerable immune stress in piglets and that this stress can be mitigated by dietary supplementation of n-3 PUFA.

This study was conducted to evaluate the influence of feeding leaf positions on the growth, net formation of fruits, and occurrence of leaf yellowing symptoms (LYS) in muskmelon plants. Plants having five or ten more leaves above the fruit-bearing node produced the greater biomass than those of plants having equal or five less leaves above the fruit-bearing node. The number of leaves above the fruit-bearing node also influenced on the occurrence of LYS. The number of plants with LYS decreased as the number of leaves borne on the nodes above the fruit-bearing node increased. The LYS infected ratio of BL-5 treatment were the greatest, while fruit weight of BL+5 treatment were the greatest among all the tested treatments. In addition, the net formation of BL-5 treatment showed the poorest. Results indicated that maintaining the higher number of leaves over the fruit-bearing node might be feasible the practical method for coping physiological damages from yellowing symptoms.
