본 연구는 ‘캠벨얼리’ 포도의 액아에서 발생하는 눈 괴사현상을 구명하고자 주아, 부아 및 액아괴사율을 생육 단계, 신초상 액아 위치, 그리고 신초의 세력 정도별로 나누어 조사하였으며, 그 결과는 다음과 같다. ‘캠벨얼리’ 포도의 주아괴사는 만개 후 30일부터 발생하기 시작하여 50일부터 60일 사이에 급증하였으며 이후 휴면기까지 완만하게 증가하였다. 부아괴사율은 주아괴사율보다는 낮게 나타났으나 같은 경향을 보였다. 주아괴사현상은 만개 30일후에는 기부의 눈(1~3번째 마디)에서 선단부의 눈보다 빨리 그리고 높게 나타났으나 시간이 경과할수록 만개 후 50~60일 사이에는 중간부위의 눈(4~9번째 마디)에서 높게 나타났다. 휴면기의 발생률은 기부나 선단부보다 4~9번째 액아에서 발생이 가장 높았다. 휴면기 주아괴사현상의 평균발생 정도는 약한 가지(신초직경 8.0㎜ 이하)에서는 28.6%, 중간 정도의 가지(8.1~11.0㎜)에서는 58.0~77.6%, 강한 가지(11.1㎜ 이상)에서는 96.8%로 나타났다. 눈의 종경에 따른 주아괴사 발생률은 4.1~5.0㎜ 크기에서 22.4%, 4.0㎜ 이하에서는 49.2~53.8%, 5.1㎜ 이상에서는 60%로 나타났다. 가지의 생장은 수령이 증가할수록 증가하였으며, 주아괴사발생도 수령이 증가함에 따라 증가하는 경향이었다. This study was carried out to investigate the incidences of main, accessory and axillary bud necrosis in different node position and cane vigour in ‘Campbell Early’ grapevines. Main bud necrosis of ‘Campbell Early’ grapevines occurred from 30 days after full bloom, increased sharply during 50~60 days after full bloom, and increased slowly from 60 to 120 days. Although rate of accessory bud necrosis was lower than main bud necrosis, main and accessory bud had same necroses pattern. Main bud necrosis occurred earlier and higher in the basal buds (1st to 3rd buds) than the more distal buds on a shoot. But as plant grew, main bud necrosis increased in the buds of middle position in shoot (4th to 9th buds) at 50~60 days after full bloom. At rest stage, the mean incidence of main bud necrosis was 28.6% in weak canes (shoot diameter below 8.0 ㎜), 58.0~77.6% in moderate canes (8.1~11.0 ㎜) and 96.8% in very vigorous canes (above 11.1 ㎜). Incidences of main bud necrosis in different longitudinal bud sizes were 22.4% in 4.1~5.0 ㎜, 49.2% to 53.8% in below 4.0 ㎜ and 60% in above 5.1 ㎜ respectively. As vine age shoot is produced strongly, thus main bud necrosis in the vines showed a tendency of continuous increase with their growth.

본 실험은 온도와 이산화탄소 농도 상승이 3년생 ‘캠벨얼리’ 포도의 수체 생육 및 과실특성에 미치는 영향을 구명하기 위해 수행하였다. 처리구는 대조구(대기온도, 390㎕·L<SUP>-1</SUP>CO₂), 온도 상승구(대기온도 + 4.0℃, 390㎕·L<SUP>-1</SUP>CO₂), 이산화탄소 상승구(대기온도, 700㎕·L<SUP>-1</SUP>CO₂), 이산화탄소 + 온도 상승구(대기온도 + 4.0℃, 700㎕·L<SUP>-1</SUP>CO₂)로 구성되었다. 평균 신초 길이는 이산화탄소 + 온도 상승구가 312.6㎝로 처리구 중 가장 높았고, 대조구는 206.2㎝, 온도 상승구와 이산화탄소 상승구는 각각 255.6, 224.8㎝이었다. 하지만 신초 직경은 온도 상승구와 이산화탄소 + 온도 상승구에서 감소하는 경향을 보였다. 과립 횡경은 이산화탄소 농도가 높을수록 증가하였고, 당함량은 이산화탄소 상승구가 14.6°Brix로 처리구 중 가장 높았으며 온도 상승구에서 13.9°Brix로 가장 낮았다. 수확기를 조사한 결과, 이산화탄소 + 온도 상승구에서는 약 11일 정도 단축되었고, 이산화탄소 상승구와 온도 상승구는 4일과 2일이 단축되었다. 생육기 광합성과 증산량을 조사한 결과, 광합성률은 이산화탄소 상승구와 이산화탄소 + 온도 상승구의 생육초기에 높았으나, 하계에 접어들면서 급격히 감소하여 증산량과 상반되었다. The effects of elevated temperature and CO₂ concentration on vine growth and characteristics of fruits of three-year-old ‘Campbell Early’ grapevine were investigated. The treatment groups consisted of a control group (ambient temperature and 390 ㎕·L<SUP>-1</SUP> CO₂), an elevated temperature group (ambient temperature + 4.0℃ and 390 ㎕·L<SUP>-1</SUP>CO₂), an elevated CO₂ group (ambient temperature and 700 ㎕·L<SUP>-1</SUP>CO₂), and an elevated CO₂/temperature group (ambient temperature + 4.0℃ and 700 ㎕·L<SUP>-1</SUP>CO₂). The average shoot length was 312.6 ㎝ in the elevated CO₂/temperature group, which was higher than the other groups; with 206.2 ㎝ in the control group and 255.6 ㎝ and 224.8 ㎝ in the elevated temperature group and elevated CO₂ group respectively. However, the shoot diameter showed a tendency of decreasing in the elevated temperature and elevated CO₂/temperature groups. The equatorial diameter of berries was increased in the higher carbon dioxide concentration, and the soluble solid content was the highest in the elevated CO₂ group, with 14.6 °Brix among all treatment groups and the lowest in the elevated temperature group (13.9 °Brix). The harvest date was approximately 11 d earlier in the elevated CO₂/temperature group and 4 to 2 days earlier in the elevated CO₂ group and elevated temperature group, respectively. Regarding the rate of photosynthesis and transpiration during the growth period, higher photosynthetic rates were observed in the elevated CO₂ group and the elevated CO₂/temperature group during the early stage of growth; however the photosynthetic rate was reduced dramatically in summer, which was contrary to transpiration.

The study was conducted to investigate the correlation analysis between fruit quality and climatic parameters in grapevines. ``Campbell Early``, one of the major grape cultivars, occupies more than 70% of cultivated areas in Korea. Recent research results have shown that the movement of cultivation area of fruit production resulted from the temperature increase. In this study, we investigated the relationship between fruit quality and climatic conditions in 13 major ``Campbell Early`` grape producing areas (i.e., Sacheon, Jinju, Naju, Dangjin, Cheonan, Gimcheon, Yeongdong, Okcheon, Sangju, Suwon, Yeongju, Gangneung, Chuncheon, and Yanggu). The earliest and latest full blooming days of grapevines were ovserved on May 25 in Sacheon area and on June 7 in Yanggu area, respectively. At least 90 days are required for grapes to mature enough for the production of highquality fruits. The southern areas with less than 90 days of maturity period had difficulty in the production of good fruit. However, the areas with longer maturity period of 100 to 110 days produced grapes with with high sugar content and good coloring. The fruit qualities of ``Campbell Early`` grapes are more closely related with temperature than other climatic factors. High temperature resulted in fruits with high acidity and delayed the coloration of the fruit skin in the southern area. The fruit skin was thin in the southern area and inclined to be thicker in the northern areas. Therefore, grape should be cultivated in regions with long maturity period to have high quality.
