This study was conducted to clarify the effects of daminozide (butanedioic acid mono-(2,2 - dimethylhydrazide)) sprayed 2 days be fore harvest and floral preservative solutions on longevity, quality and ethylene production of 'Georgia' cut lily for prolonging vase life and improving quality of cut lily flowers. And also the relation between ethylene production and flower senescence of cut lily was studied. 1. Lilies held in silver nitrate ($AgNO_3$) at 25 and 50 ppm were increased in solution uptake, fresh weight, and flower longevity. The solution of 2.5% sucrose+50 ppm $AgNO_3$+200 ppm aluminum sulfate+10 ppm 6-benzylamino purine prolonged vase life and improved quality of cut lily flowers. 2. Lilies sprayed with 500 ppm daminozide 2 days be fore harvest and then held in the preservative solution (5% sucrose+50 ppm $AgNO_3$+150ppm 8-hydroxyquinoline) after harvest were significantly increased in fresh weight and vase life as compared with non-sprayed (control) flowers. 3. Ethylene production from cut lily was increased by ethephon ((2-chloroethyl) phosphonic acid) treatment. The flowers producing a lot of ethylene, however, were senesced slowly instead of rapid wilting. 4. The preservative solution markedly reduced ethylene production of cut lily but prolonged vase life for only a few days. 5. These results suggest that ethylene be one of the most important factors promoting flower senescence of cut lily, but it be very difficult to prolong vase life remarkably by only inhibition of ethylene production in cut lily.

To lesson economical loss induced by fumigation in importing country when cut roses are exported, effects of several fumigation temperature, treatments of cut stems (dry or wet), methyl bromide (MB) concentrations, and fumigation periods on the quality of cut roses were investigated. According to results, the most important factor affecting the quality of cut rose was found to be fumigation temperature. When fumigated at $5^{\circ}C$, cut roses showed no chemical damages, e.g., tip burn or bent neck, and maintained their quality for the same duration as that of control, regardless of MB concentrations or treatments of cut stems. However, phytotoxicity by MB increased and vase life of cut rose was shortened as fumigation temperature increased. Timing of fumigation also appeared to be an important factor affecting the quality of cut roses of which phytotoxicity by MB was not observed and thier vase life was not shortened, even if MB was treated up to $40g{\cdot}m^{-3}$, when cut roses were fumigated at $5^{\circ}C$ on the day of harvesting. On the other hand, the degree of damage of cut flowers by fumigation methods or MB concentraions was not consistent with changes in fumigation temperature.

One-year old pear (Pyrus pyrifolia L.) trees of a new commercial cultivar 'Manpungbae', recently developed in South Korea, were planted in 2001 (planting year 1) and trained to four trellis systems: Y-trellis, Y-II-trellis, pergola, and vase-pergola. To evaluate training systems in the local area (southern Korea), tree growth responses were compared for each trellis system from planting years 3 to 8. For trees trained to Y-trellis and pergola systems, a high proportion of land covered by tree canopy was maintained over the study duration, with 70-80% coverage in year 8. Eight-year cumulative yield per tree was increased in the vase-pergola system with a low planting density and an additional scaffold. Compared with other systems, cummulative yield use efficiency was greatest in Y-II-trellis and pergola systems in years 5 and 8. Compared with Y-II-trellis and vase-pergola systems, the 8-year cumulative yield per hectare was two fold greater for trees trained to the Y-trellis (103 tons) and pergola systems (101 tons). Use of the pergola system improved average fruit weight and fruit soluble solid contents, as well as net income in year 8. Given that we observed reduced fruit productivity and increased labor hours (pruning and orchard work), we consider the Y-trellis and pergola systems to be less valuable trellis systems than the others evaluated.

Sugars play important roles in petal senescence of cut flowers. In the Expt. 1 of this study, the effects of different concentrations of glucose (60, 90, and $120g{\cdot}L^{-1}$) and sucrose (30, 60, and $90g{\cdot}L^{-1}$) application on the vase life, rate of flower diameter increase, rate of flower weight increase and ethylene production of cut tree peony (Paeonia suffruticosa 'Luoyang Hong') were evaluated. At the earlier stage, treatments of different concentrations of glucose and sucrose all retarded the process of flower opening and inhibited the increase of flower diameter and weight, while senescence of flowers fed with different concentrations of glucose was delayed at later stage. Flowers treated with $90g{\cdot}L^{-1}$ glucose displayed the longest vase life, which showed significant difference (P < 0.05) from those of flowers with the control and sucrose treatments. All treatments with glucose or sucrose not only retarded the decrease of flower diameter and weight, but also suppressed the ethylene production at the earlier stage and delayed the peak of ethylene evolution. In order to study the effect of exogenous sugar on the postharvest response of cut tree peony to ethylene, Expt. 2 was conducted. Cut flowers were treated with $90g{\cdot}L^{-1}$ glucose for 4 hours before (GE) or after (EG) exposed to $10{\mu}L{\cdot}L^{-1}$ ethylene for 4 hours. Generally, the opening process of flowers with GE and EG treatments was similar to that of the control, however GE treatment delayed flower senescence. Both GE and EG treatments improved flower diameter and weight, and GE treatment delayed the time of flower weight decrease. Besides, GE delayed climacteric ethylene evolution for 8 hours. All above suggest that exogenous sugars delay tree peony 'Luoyang Hong' cut flower senescence and extend flower vase life through their roles in the decrease of water loss and the suppression of sensitivity to ethylene and ethylene production.

Purpose: Ti thin films were deposited on slide glass and CR-39 lenses using small magnetron sputtering apparatus to of Ti thin films. Methods: The thickness of Ti thin films were measured by cross section SEM, the transmittance and reflectance of them were obtained using spectrophotometer, the refractive index and extinction of them were obtained from VASE data. Results: The transmittances of Ti thin films with 60 nm, 120 nm, 140 nm thickness were a little change within the visual region from 400 nm to 750 nm, but were increased a little amount at near 400 nm. The transmittance of 60 nm, 120 nm, 140 nm Ti thickness in d-line was 30%, 25%, 20%, respectively. Also, it was shown that the refractive indices and extinction coefficients of the Ti thin films obtained from VASE were similar to those of Ti thin film offered macleod program. Conclusions: Ti films on CR-39 with these transmittances were available for sunglass lens. It was indicated that the refractive indices and extinction coefficients of the Ti thin films were decreased with the thickness of Ti thin film, for the thickness of Ti thin films was due to very thin.
