본 실험은 지베렐린이 '신고'배 숙기와 비대에 미치는 영향을 조사하기 위하여 실시되었다. 과실중 조사에서 모든 Gibberellic acid $A_{4+7}$ 처리구는 대조구인 지베렐린 도포제와 비등한 약효가 나타났으며, 무처리구에 비해서는 증가를 나타내었다. 횡경은 $GA_{4+7}$을 만개후 35일째에 도포한 것이, 종경은 만개후 40일째 도포한 것이 가장 효과적인 것으로 나타났으며, 과형지수는 모든 처리구에서 비슷한 수치로 나타났다. '신고'배 발달 초기에는 $GA_{4+7}$ 2.4% 처리구가 $GA_{3}+GA_{4+7}$ 2.7% 처리구나 무처리구보다 현저하게 큰 차이로 비대가 되는 것을 볼 수가 있으나, 성숙기에 들어서면 $GA_{4+7}$ 2.4% 처리구와 $GA_{3}+GA_{4+7}$ 2.7% 처리구의 크기와 가시적인 착색도가 거의 비슷해지는 것을 볼 수 있었다. $GA_{3}+GA_{4+7}$의 성숙촉진 효과를 검토하기 위하여 에테폰 액제와 비교하여 실험한 결과, $GA_{3}+GA_{4+7}$를 만개후 35일째에 어린 과실에 도포한 것이 에테폰과 비슷한 정도로 착색이 되었으며, 무처리구와 비교했을 때에는 모든 $GA_{3}+GA_{4+7}$ 처리구와 에테폰 처리 모두 착색이 6일정도 빨라 착색 속도에 현저한 차이를 보여주었다. 모든 $GA_{3}+GA_{4+7}$ 처리구는 무처리구에 비하여 당도는 증가하고 산도는 감소하였으며, 과실의 경도는 무처리구보다 낮은 것으로 나타났으나 유의한 차이는 없었다. 상기의 결과로 $GA_{3}+GA_{4+7}$ 처리구 모두가 에테폰이나 무처리구보다 과실의 비대에 있어 효과가 큰 것으로 나타났다. 특히 $GA_{3}+GA_{4+7}$를 만개후 35일째에 처리한 것이 횡경 및 종경, 과형지수 모두 가장 높게 나타났으며 착색 또한 깔끔하게 되어 상품성이 높게 평가되었다.

Two different pest control programs were applied on 8-year-old 'Ryoka'/M.26 apple trees (Malus domestica Borkh.). Lime sulfur or Bordeaux mixture with emulsified oil were applied 12 times from late March to mid-September as organic treatment, and synthetic chemicals were 7 times applied as control treatment. Over the entire apple-growing season, photosynthesis rates of apple trees were significantly lower in the organic treatment than in the control, and this photosynthetic differences were larger in July and August. Photosynthesis-related parameters such as stomatal conductance and transpiration behaved similarly to photosynthesis. The leaf area in the organic treatment was significantly smaller ($24.7cm^2$) than that in the control treatment ($30.7cm^2$). Organic leaves contained significantly less Chl. a ($15.5mg{\cdot}g^{-1}$) than did control leaves ($17.6mg{\cdot}g^{-1}$). Fruit yield per tree was significantly lower in the organic treatment (18.8 kg) than in the control (24.5 kg), because organic fruits experienced a higher rate of disease infection such as white rot (Botryosphaeria dothidae) and bitter rot (Glomerella cingulata) than did control fruits. Organic fruits had high flesh firmness but less color development (lower Hunter's a values). In this experiment, the pest control program with frequent applications of organic fungicides showed negative effects on photosynthesis and disease infection on leaves and fruits, and thus reduce the fruit quality and yield in 'Ryoka'/M.26 apple trees.

This study was carried out to investigate of the quality characteristics of the starch Oddi Dasik(MSOD) manufactured with various addition levels (0, 5, 10, 18 and 28%) of mulberry fruit (Oddi) juice (MFJ), with various levels(55%, 50%, 45%, 37% and 27%) of sucrose syrup, and with the ratio of rice powder: mungbean starch (1:4) according to the traditional Korean Dasik (a kinds of cookie) methodology. The nutritional components of Oddi and MSOD were examined, and sensory evaluation and physical tests of MSOD added MFJ were conducted. The results are summarized as follows. In Oddi, the contents of moisture, crude fat, crude protein, crude ash, and vitamin C, and the levels of acidity, pH and sugar were 88.45%, 0.245%, 2.23%, 0.88%, 53.20 mg%, 8.00%, 4.41 and 11.0 Brix%, respectively. In MSOD (Oddi 10%), the contents of moisture, crude fat, crude protein, and crude ash, were 22.8%, 0.117%, 9.2% and 0.8%, respectively, and were all increased with increasing MFJ amount. In MSOD (Oddi 10%), the contents of Ca, Mg, K and Fe were 63.2 mg%, 70.9 mg%, 376.0 mg% and 7.7 mg%, respectively. and were increased with increasing MFJ amount. For the establishment of the additional amount of MFJ, sensory evaluation and physical tests were conducted. From the total characteristics of sensory evaluation, the MSOD with 10% MFJ was judged as the best. Color L and b values of MSOD significantly decreased and a value increased with increasing MFJ percentage. Hardness, gumminess, adhesiveness and chewiness among the texture characteristics of MSOD were significantly increased with increasing MFJ amount. However, there were no significant differences in springiness and cohesiveness of the MSOD. In conclusion, the optimal added amount of MFJ for the manufacture of the MSOD was proposed to be 10% of the total weight.

BACKGROUND: The use of green manure and compost as organic fertilizer may increase crop yield and soil fertility due to improved soil nutrient availability and soil organic matter content (SOM). This study aimed to investigate the effects of hairy vetch (Vicia villosa L.) and compost application on red pepper growth, yield, fruit quality and soil health. METHODS AND RESULTS: The treatments were no fertilizer (CON), chemical fertilizer (CF), hairy vetch (HV), and livestock compost+HV (LC+HV). Red pepper seedlings (70 days old) were transplanted and maintained in experimental plots for 140 days. Plant dry weight, micro- and macronutrient contents of plants and soil chemical properties were determined. All fertilizer treatments significantly increased plant dry weight. Fruit yield was significantly highest with HV treatment. As for nutrient content, plants in HV and LC+HV treatments have significantly higher K and Ca contents than the other treatments. Regarding soil properties, HV and LC+HV application significantly altered the soil chemical properties. Significantly higher SOM was observed in HV and LC+HV treated soils. CONCLUSION: The results of this study suggest that short-term application of hairy vetch and compost is an effective alternative to the conventional chemical fertilizer to increase fruit yield red pepper and improve soil health.

As apple trees mature, it is important to maintain good light distribution within the canopy to produce marketable fruits. Tree thinning is the selective removal of a proportion of trees growing in the orchard to provide more growing space and a good light environment for the remaining trees. This study was conducted over 3 years (14-16 years after planting) to investigate the influence of tree thinning on vegetative growth, yield, fruit quality, and blooming in the 14 years old slender spindle 'Fuji'/M.9 apple trees planted with the tree space of 3.2×1.2 m. The trees were placed in a control group (no thinning; 260 trees per 10 a) or a tree thinning group (thinned 50% of the control; 130 trees per 10 a). The tree thinning successfully improved light penetration, yield per tree, fruit red color, and yield efficiency for 3 years, and the tree thinning controlled the occurrence of biennial bearing. However, tree thinning significantly decreased accumulated yield per 10 a compared with the control. The vegetative growth, yield per tree, soluble solid contents, and blooming were not clear by the occurrence of biennial bearing in the control. These results indicated that tree thinning was a good method for improving light penetration and preventing biennial bearing in the old 'Fuji'/M.9 high-density apple orchards.

In this study, Green apple from Mungyeong area was used as material in the fermentation process. In apple fruit growing process, to produce a high quality apple fruit, some Green apple should be removed. Since the removed Green apple fruit is inedible, it doesn't have any economical value. To solve this problem, this paper proposed fermentation process to increase the economical value of raw apple as a fermentation product. This research conducted seven days, and the pH and brix value analysis was done every 12 hours during fermentation process. The experimental results show that the fermentation product under blender treatment is better than cutting treatment and without cutting treatment. Initial brix 25% is the best treatment for fermentation because produce fermentation product with a good taste and aroma than other treatment.

The purpose of this study was to investigate the qualitative changes of the citron by identifying the type of solution and addition of the solution to prevent the browning reaction of the citron in a way that inhibits the browning of the citron. The browning inhibitor solution was investigated using the individual and mixture, and the results of the degree of browning and chromaticity showed that vitamin C+NaCl+cyclodextrin (CD) had the lowest browning of 0.52. In chromaticity, the ΔE values indicate that the higher the value, the greater the change in color, and the lowest value of the vitamin C+NaCl+CD mixture was 47.0, indicating that there was minimal browning compared to other treatment. The active change of the polyphenol oxidase (PPO) in the citron increased enzyme activity as the browning progressed, and the vitamin C+NaCl+CD solution was the lowest at 68.40 μ/g among the anti-browning solution. Based on these research results, it seems that the CD mixing solution can be used as a citron browning inhibitor.
