장미는 전세계적으로 가장 많이 생산되는 화종 중 하나로, 절화 장미는 시설 내부에서 연중 생산된다. 최근 여름철 시설 내부 온도 상승으로 인해 절화장 단축 등 절화 장미의 품질 저하가 심각하게 발생하고 있다. 본 연구는 계절별 절화 품질 및 수량을 비교하여 여름철 생산된 절화 장미의 품질 특성을 파악하고, 고온기 야간 냉방을 통한 온도 하강 효과와 여름철 절화 품질 개선 효과를 검정하고자 수행하였다. 'Pink Beauty'은 여름철 절화장, 화수장, 경경, 화수경경, 화폭, 생체중 등이 통계적으로 유의하게 저하되었으며, 'Pink Shine'은 여름철 절화장, 경경, 화폭 및 화고, 생체중이 통계적으로 유의하게 저하되었다. 고온기 야간 냉방을 수행한 결과, 7-8월 온실 내부 평균 온도는 약 2.5℃ 저하되었으며, 배지 평균 온도는 약 3.0℃ 감소되었다. 고온기 야간 냉방 시 절화 품질 및 수량을 비교한 결과 세 품종 모두 야간 냉방 시 절화장, 생체중, 경경 등 절화 품질이 향상되었다. 이를 통해 고온기 야간 냉방이 여름철 절화 장미의 품질 저하 문제 해결에 도움이 될 것으로 기대된다.

The present studies were carried out to obtain some basic informations of the breeding of tobacco varieties. Genetically divergent 8 varieties, 3 flue-cured, 2 burley and 3 sun-cured tobaccos, were used in half diallel cross. In order to analyze the heterosis, combining abilities, modes of inheritance and correlations for some agronomic and chemical characters, 8 parents and 28 $F_1$ were tested. The results obtained were summarized as follows: The percentages of heterosis for stem diameter, internode length and total sugar content in $F_1$ hybrid were 3.6%, 3.1% and 10.6%, whereas these for days to flower, total alkaloids and leaves per plant were -6.3%, -6.9% and -5.0%, respectively. Yield had significant positive genotypic correlations with plant height, days to flower and leaf length, but negative with internode length and total sugar content. It also had significant prositive phenotypic correlations with plant height, days to flower, leaves per plant, leaf length, leaf width and leaf shape index (Leaf length/leaf width). General (GCA) and specific combining abilities (SCA) for all characters of $F_1$ hybrid were significant. The effects of GCA were positive on yield, plant height, stem diameter, leaves per plant and days to flower of Burley 21. And those were positive on yield, leaf shape index and plant height, but negative on leaves per plant and total nitrogen of Hicks. The effects of SCA for yield and leaves per plant were greater than those of others on the combinations of Coker 139 and Burley type, respectively.

Rose and chrysanthemum are the most popular flowers in Korean floriculture. Sorting flowers is a labor intensive operation in cultivation of the cut flowers and needed to be mechanized. Machine vision is one of the promising solutions for this purpose. This study was carried out to develop hardware and software of a cut flower sorting system using machine vision and to test its performance. Results of this study were summarized as following; 1. Length of the cut flower measured by the machine vision system showed a good correlation with actual length of the flower at a level of the coefficients of determination (R$^2$) of 0.9948 and 0.9993 for rose and chrysanthemum respectively and average measurement errors of the system were about 2% and 1% of the shortest length of the sample flowers. The experimental result showed that the machine vision system could be used successfully to measure length of the cut flowers. 2. Stem diameter of the cut flowers measured by the machine vision system showed a correlation with actual diameter at the coefficients of determination (R$^2$) of 0.8429 and 0.9380 for rose and chrysanthemum respectively and average measurement errors of the system were about 15% and 7.5% of the shortest diameter of the sample flowers which could be a serious source of error in grading operation. It was recommended that the error rate should be considered to set up grading conditions of each class of the cut flowers. 3. Bud maturity of 20 flowers each judged using the machine vision system showed a coincidence with the judgement by inspectors at ranges of 80%∼85% and 85%∼90% for rose and chrysanthemum respectively. Performance of the machine vision system to judge bud maturity could be improved through setting up more precise criteria to judge the maturity with more samples of the flowers. 4. Quality of flower judged by stem curvature using the machine vision system showed a coincidence with the judgement by inspectors at 90% for good and 85% for bad flowers of both rose and chrysanthemum. The levels of coincidence was considered as that the machine vision system used was an acceptable system to judge the quality of flower by stem curvature.

This experiment was conducted to investigate the effect of root zone heating on the growth of cut minirose Rosa hybrida L. ′Little Marble′ in winter season. Effects of four different root zone temperatures of 16, 20, 24$^{\circ}C$ and non-heating control on the growth and productivity were compared. Harvested cut-flowers were measured for stem length, stem diameter, fresh and dry weights, numbers of leaves, stems and flowers, days to flower, and chlorophyll concentration. The results showed that mean height was the greatest at 16$^{\circ}C$. Days to flower was the shortest at 24$^{\circ}C$. Fresh and dry weights of top (shoot＋leaf＋flower), shoot and leaf were the greatest at 2$0^{\circ}C$. Stem and flower numbers were the greatest at 16$^{\circ}C$, but leaf number was the greatest at 2$0^{\circ}C$. Mean cut flower yield was the greatest at 16$^{\circ}C$. Chlorophyll concentration was slightly higher at 16$^{\circ}C$, but was not significantly different among the treatments. Stem diameter was the greatest at 2$0^{\circ}C$. Dry matter was the greatest at 24$^{\circ}C$. Total yield of cut rose stems increased with increasing temperature. Combined heating could save 24% in fuel cost as compared to the air heating alone. The results obtained suggested that optimal root zone temperature for the growth of cut rose "Little Marble" was 2$0^{\circ}C$, and the greenhouse heating energy can be saved by minimal air heating combined with root zone heating to 2$0^{\circ}C$.

A prototype cut-flower sorter was developed and tested for its performance with five varieties of roses. Support plates driven by a chain mechanism transported the roses into an image inspection chamber. Color image processing algorithms were developed to evaluate the length, thickness, and straightness of stem and color, height, and maturity of bud. The average absolute errors of the system for the measurements of stem length, stem thickness, and height of bud were 19.7 mm, 0.5 mm, and 3.8 mm, respectively. The results of classification by the sorter were compared with those of a human inspector for straightness of stem and maturity of bud. The classification error for the straightness of stem was 8.6%, when both direct image and reflected image by a mirror were analyzed. The accuracy in classifying the maturity of bud varied among the varieties, the smallest for‘Nobless’(1.5%) and the largest for‘Rote Rose’(13.5%). The time required to process a rose averaged 2.06 seconds, equivalent to the capacity of 1,600 roses per hour.
