정삼택,김유신,전상항,김익홍 경북대학교 1990 새마을 硏究論叢 Vol.11 No.-
양앵두 佐藤錦 및 Napoleon品種을 供試하여 Ca(OH)_2 處理濃度 및 處理回數에 따른 果實生長, 果實品質, 칼슘축적 및 裂果에 미치는 影響을 調査하였던바 다음과 같은 結果를 얻었다. 1. 양앵두 果實生長은 佐藤錦품종에서 收穫1週前 Ca(OH)_2 처리농도간에는 차이가 없었으나, Napoleon품종에서 Ca(OH)_2 처리회수가 증가 할수록 抑制되었다. 2. 可溶性 固形物과 Anthocyanin함량은 Ca(OH)_2 처리농도 및 처리회수를 증가 할수록 감소하였으나, 유기산 함량은 증가하였다. 3. 果實內 칼슘축적은 Ca(OH)_2 처리농도 및 처리회수가 증가 할수록 증가하였고, 佐藤錦 품종에서 과실내 칼슘함량은 과피, 종자, 과육, 핵의 순이였고, Napoleon품종에서는 종자, 과피, 과육, 핵의 순이였다. 4. 裂果방지를 위한 Ca(OH)_2 처리는 7.2g/l를 수확 3주전부터 1週間隔으로 3회 살포하는 것이 열과를 감소시키는데 효과적이였다. The study was conducted to investigate the influences of several concentrations of Ca(OH)_2 and application time on fruit growth, quality, contents of Ca in fruits and cracking of 'sa Tou Nisiki' and 'Napoleon' sweet cherry. The results obtained are summarized as follows; 1. In Ca(OH)_2 treatments, the fruit growth of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry was not influenced by its concentrations but by application times of Ca(OH)_2. 2. Contents of soluble solids and anthocyanin according to concentreation and application of Ca(OH)_2 were decreased, while titratable acidity was increased respectively. 3. Contents of Ca in the fruit according to concentration and application of Ca(OH)_2 were increased and Ca contents in both fruits differ from fruit portions. 4. Preharvest application of Ca(OH)_2 by 0.72% and three times applications reduced cracking of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry. From these results, twice applications of Ca(OH)_2 to the sweet cherry are recommended for the best fruit quality, the authors believed.
Interaction of Gas-phase Atomic Hydrogen with Chemisorbed Oxygen Atoms on a Silicon Surface
Sang Kwon Lee,Jongbaik Ree,Yoo Hang Kim,Hyung Kyu Shin 대한화학회 2011 Bulletin of the Korean Chemical Society Vol.32 No.5
The reaction of gas-phase atomic hydrogen with oxygen atoms chemisorbed on a silicon surface is studied by use of the classical trajectory approach. We have calculated the probability of the OH formation and energy deposit of the reaction exothermicity in the newly formed OH in the gas-surface reaction H(g) + O(ad)/Si→OH(g) + Si. All reactive events occur in a single impact collision on a subpicosecond scale, following the Eley-Rideal mechanism. These events occur in a localized region around the adatom site on the surface. The reaction probability is dependent upon the gas temperature and shows the maximum near 1000 K, but it is essentially independent of the surface temperature. The reaction probability is also independent upon the initial excitation of the O-Si vibration. The reaction energy available for the product state is carried away by the desorbing OH in its translational and vibrational motions. When the initial excitation of the O-Si vibration increases,translational and vibrational energies of OH rise accordingly, while the energy shared by rotational motion varies only slightly. Flow of energy between the reaction zone and the solid has been incorporated in trajectory calculations, but the amount of energy propagated into the solid is only a few percent of the available energy released in the OH formation.

Salinity is one of the major abiotic stresses that cause reduction of plant growth and crop productivity. It has been reported that plant growth-promoting bacteria (PGPB) could confer abiotic stress tolerance to plants. In a previous study, we screened bacterial strains capable of enhancing plant health under abiotic stresses and identified these strains based on 16s rRNA sequencing analysis. In this study, we investigated the effects of two selected strains, Bacillus aryabhattai H19-1 and B. mesonae H20-5, on responses of tomato plants against salinity stress. As a result, they alleviated decrease in plant growth and chlorophyll content; only strain H19-1 increased carotenoid content compared to that in untreated plants under salinity stress. Strains H19-1 and H20-5 significantly decreased electrolyte leakage, whereas they increased Ca<sup>2+</sup> content compared to that in the untreated control. Our results also indicated that H20-5-treated plants accumulated significantly higher levels of proline, abscisic acid (ABA), and antioxidant enzyme activities compared to untreated and H19-1-treated plants during salinity stress. Moreover, strain H20-5 upregulated 9-cisepoxycarotenoid dioxygenase 1 (NCED1) and abscisic acid-response element-binding proteins 1 (AREB1) genes, otherwise strain H19-1 downregulated AREB1 in tomato plants after the salinity challenge. These findings demonstrated that strains H19-1 and H20-5 induced ABA-independent and -dependent salinity tolerance, respectively, in tomato plants, therefore these strains can be used as effective bio-fertilizers for sustainable agriculture.

Certain beneficial microorganisms isolated from rhizosphere soil promote plant growth and induce resistance to a wide variety of plant pathogens. We obtained 49 fungal isolates from the rhizosphere soil of paprika plants, and selected 18 of these isolates that did not inhibit tomato seed germination for further investigation. Based on a seed germination assay, we selected four isolates for further plant tests. Treatment of seeds with isolate JF27 promoted plant growth in pot tests, and suppressed bacterial speck disease caused by Pseudomonas syringae pathovar (pv.) tomato DC3000. Furthermore, expression of the pathogenesis-related 1 (PR1) gene was higher in the leaves of tomato plants grown from seeds treated with JF27; expression remained at a consistently higher level than in the control plants for 12 h after pathogen infection. The phylogenetic analysis of a partial internal transcribed spacer sequence and the b-tubulin gene identified isolate JF27 as Aspergillus terreus. Taken together, these results suggest that A. terreus JF27 has potential as a growth promoter and could be used to control bacterial speck disease by inducing resistance in tomato plants.
