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.

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.

"Campbell Early", a major grape cultivar, occupies more than 70% of cultivated vineyard areas, however, recommendable standard management system of soil environmental conditions has not been developed yet in Korea. The consideration for the correlation between fruit quality and soil condition in the vineyard is required in the efficient management system of soil. This study was carried out to investigate the optimum soil environmental conditions for "Campbell Early" grape production with high quality. The results from analyses of correlation between them were used to develop soil management guideline for promoting efficiency in grape production. Soil properties were analyzed from 120 vineyards in Hawsung, Sangju, Yeongdong, Gimcheon, Yeongju, and Yeongwol, major grape production regions. Because there is neither coloring disorder nor delayed coloration in grape production of "Campbell Early", relative contribution of soil hardness and solid phase to fruit quality and fruit weight was analyzed. Among the soil properties, while cation and soil hardness affected sugar content at the level of 39.3% and 36.8%, respectively, saturated hydraulic conductivity, solid phase, and cation exchange capacity (CEC) showed relatively low contribution to sugar content in the vineyard. The sugar content in grapes was influenced more critically by the chemical properties than the physical ones in the soil of vineyards. While soil hardness and solid phase affected grape weight at the level of 27.8% and 26.0%, respectively, phosphate content, organic matter content, and cation showed low contribution to grape weight. Grape guality such as sugar content and grape weight was affected highly by cation and organic matters. Therefore, cation and organic matter content of soil contributed to fruit quality at the level of 33.8% and 15.5%, respectively, in the vineyard.

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.

This study investigated the effects of flower and fruit thinning agents on fruit set and harvested fruit quality attributes in ‘Gamhong’ apples. Lime sulfur, MaxCel (1.9% BA), and Fruitone (3.5% NAA) were applied either at post-bloom or fruitlet stages to mature ‘Gamhong/M.9’ trees. In 2011, the numbers of fruits per cluster in terminal flowers were 1.74, 0.82, and 1.15 for the control, lime sulfur, and Maxcel (applied at 10-mm fruit stage) treatments, respectively. The percentages of single fruit per cluster were 36.0, 47.9, and 48.7% for the control, lime sulfur, and Maxcel (10 mm) treatments, respectively, while the percentages of clusters with three fruits per cluster were 22.9, 1.4, and 5.8%. In lateral flowers, fruit numbers per cluster were 1.20, 0.36, and 0.50 for the control, lime sulfur, and Maxcel (10 mm) treatments, respectively. In 2012, all the thinning treatments showed a positive effect on flower and fruit thinning, compared with the control. Moreover, the treatment with thinning agents did not affect fruit quality. Overall, the results suggest that a single application of flower or fruit thinning agents would be sufficient, rather than the mixed application of thinning agents, based on the observed decrease in fruit setting.

Wine grape is characterized by small berry-type fruits, which contain seeds and juicy pulp enclosed in thick skin. ‘Cheongsoo’, a Korean grape cultivar selected in 1995, is rich in flavor and used as both a wine and a table grape. The effects of growth regulator treatments including GA₃ alone or in combination with thidiazuron (TDZ) or forchlorfenuron (FCF) have been studied in different Korean grape cultivars to select for traits such as seedless and firm fruits and to prevent berry shatter. However, growth regulators such as cytokines have been shown to delay the growth of grapes. Here, we assessed the effect of three growth regulators on ‘Cheongsoo’ grape through investigation of grape quality characteristics and the development of volatile flavor components. Three treatments of growth regulators, specifically 100ppm GA₃ + 5ppm 1% TDZ, 100ppm GA₃ + 5ppm 0.1% FCF and 100ppm GA₃ alone, were applied at 14 days after full bloom while untreated grapes were used as control. Five quality characteristics of ‘Cheongsoo’ grape were investigated including the sugar, fatty acid and n-alkane contents, acidity and the degree of volatile compound production. Treatment with growth regulators resulted in greater average fruit weight of 6.30–6.48g compared to the 4.49 g of untreated grapes. However, the sugar content of untreated grapes was 1°Brix higher (16.6 ± 0.55) than that of grapes treated with growth regulators. Similarly, the volatile compound and acid content of untreated grapes were elevated, with the latter being 0.67 ± 0.04% (w/v), which was 0.1% higher than grapes treated with growth regulators. The content of hexanal, (E)-2-hexenal, 4-hexen-1-ol, and (E)-2-hexen-1-ol derived from the C<SUB>6</SUB> compounds and fatty acids were higher in grapes treated with growth regulators, also these compounds appeared abundant in immature fruits. The n-alkane content was more predominant in untreated grapes, mostly in the wax layers of grape skin, and it was degraded to fatty acids through various pathways. Collectively, treatment of Cheongsoo grape with growth regulators resulted in reduction of fruity volatile compounds that are essential for the production of good quality wine grapes.

This study was conducted to develop an efficient spray calendar to control diseases in production of grapes to be exported to United States of America and Hong Kong by use of fungicides permitted by maximum residue levels (MRLs) in both USA and Hong Kong in ‘Campbell Early’ (Sangju, Gyeongbuk) and ‘Kyoho’ (Gyeongsan, Gyeongbuk) vineyards managed in Wakeman’s training system under the rainshelter system. Fungicides including azoxystrobin, boscalid, difenoconazole, dimethomorph, fenhexamid, fludioxonil, iprodione, kresoxim-methyl, pyraclostrobin, myclobutanil, tebuconazole, trifloxystrobin, were preliminarily selected and sprayed to the vineyards at vine growing stages, which are before budding, before blooming, berry development, veraison, and ripening stages in 2015 to 2016. After fungicides were sprayed as scheduled in the vineyard, the incidence of diseases on the trees was counted before fruit harvest, and characteristics and chemical residues were investigated in harvested fruits. Leaf spot were shown to be inhibited the most effectively in treatment 2 in vineyards for exportation to USA, and in treatment 2 in vineyards for exportation to Hong Kong in 2015, and in treatment 4 for exportation to both countries. There is no significance between fungicide treatment and non-treatment in fruit characteristics such as cluster weight, berry weight and total soluble solid contents. Chemical residue was never detected or was detected in the levels lower than MRL in fungicide-sprayed treatment. Selected chemicals and optimum timing to spray them in vineyards in this study can provide very useful information in developing efficient safe spray calendar which is acceptable for grape importing countries, and to promote exportation of Korean grapes to foreign countries.

This work was carried out to evaluate the effects of preharvest 1-methylcyclopropene (1-MCP, Harvista™) and postharvest 1-MCP (SmartFresh™) treatments on t he f ruit q uality a ttributes o f cold-stored ‘Fuji’ ( Malus domestica Borkh.) apples. Fruits were exposed to 0, 95, 125, or 250 ㎎·L<SUP>-1</SUP> Harvista™ at 3, 2, 1 weeks before harvest (WBH), and treated with 0 or 1 μL·L<SUP>-1</SUP> SmartFresh™ at harvest. Fruit was then stored for up to 180 days at 0 ± 1℃. Fruit fresh weight, Hunter’s value a, internal ethylene concentration (IEC), flesh firmness, titratable acidity (TA), and soluble solids content (SSC) in fruit treated with Harvista™ were not different from those of control fruit at harvest. During cold storage, flesh firmness and TA were higher in fruit treated with 250 ㎎·L<SUP>-1</SUP> Harvista™ at 2 and 3 WBH than in control fruit. IEC was 5.5-10.0% lower in fruit treated with 250 ㎎·L<SUP>-1</SUP> Harvista™ at 2 and 3 WBH compared with control fruit as storage duration progressed, while SSC was not affected. Furthermore, flesh firmness, TA, and IEC were affected neither by Harvista™ nor Harvista™ + SmartFresh™ treatments, compared with those fruit quality attributes at harvest. The correlation maps indicated that IEC was negatively correlated with firmness and TA, regardless of Harvista™ application levels. In addition, positive correlations between fruit quality attributes were detected in treatments with 250 ㎎·L<SUP>-1</SUP> Harvista™ + SmartFresh™. Therefore, the results suggest that with a single application of SmartFresh™, a higher level of Harvista™ application would help in retention of fruit quality attributes during cold storage.
