Yeong-am's 'Jeongwon (貞元)' stone monument, designated as the Jeollanam-do Cultural Heritage, is considered to be the oldest of the epigraphs in Jeollanam-do. Immediately after the discovery, the possibility of it being a Maehyangbi of Memorial Inscriptions was mentioned and attracted attention. However, there is an absolute age of the 'Jeongwon (貞元) of 2 years' (786), so despite it is a relatively early epigraph (金石文), there are not many papers on the theme related to this stone monument. I believe that this stone monument is a Maehyangbi (埋香碑). While reviewing and comparing the results of the existing research, I decoded the text from the 42nd character of the 4th line. As a result of the review, that was conducted, it was confirmed that this stone monument is truly a Maehyangbi (埋香碑). In particular, it was recorded in the literature of the late Joseon Dongguk-myungsanggi (東國名山記) that the letters of the Maehyangbi (埋香碑) are not recognizable. However, it is clearly stated that this stone monument is a Maehyangbi (埋香碑). Although there is no common expression for 'bury (埋)' or 'incense burial (埋香)' in the traditional Maehyangbi (埋香碑), which were popular in the late Goryeo and early Joseon Periods, it can be seen that it is a Maehyangbi (埋香碑) from the words "hide (呑藏)" and "10 bundles of fragrant incense (合香十束)" that are engraved on the stone monument with the name 'Jeongwon.' In other words, it is thought that it meant 'hide (呑藏)' instead of 'bury (埋)'. Circumstantial evidence for the monument of Jingamseonsa (眞鑑禪師), built in 888, contains the an epigraph from the Unified Silla Era. There is a phrase on it that says 'Plant incense on the shore (海岸植香)' on the monument of Jingamseonsa (眞鑑禪師), and it conveys its meaning without using the character 'bury (埋)'. As a result of the absence of the character 'bury (埋)' on the stone monument with the name 'Jeongwon', it is not considered as a Maehyangbi (埋香碑). However, there is evidence that the stone monument with the name 'Jeongwon (貞元)' is in fact a Maehyangbi (埋香碑) and it is also in the Geumpyoseok (禁標石; Forbidden Stone) around Gukjangsaeng (國長生) and at the entrance of Dogapsa Temple (道甲寺). The letters written on the gold sign suggest the possibility that the charcoal used to burn incense (香炭) at the royal tombs of King Jeongjo (正祖) was produced around at Dogapsa Temple (道甲寺) in Wolchulsan (月出山). Since the charcoal used to burn incense (香炭) is naturally related to incense (香), it has been shown that the area around Wolchulsan, where Dogapsa Temple is located, has a long history related to incense (香). The letters visible on the stone monument, the record of Dongguk-myungsanggi (東國名山記) in the late Joseon Dynasty, and the letters on the Geompyoseok (禁標石; Forbidden Stone), all show that the stone monument with the name 'Jeongwon (貞元)' is a Maehyangbi (埋香碑). Considering the fact that the earliest Maehyangbi (埋香碑) in existence is the Maehyangbi (埋香碑) in Yeongam (靈巖) Ippam-ri (笠巖里), which has two dates from 1371 at the end of Goryeo and 1410 at the beginning of Joseon, the stone monument with the name 'Jeongwon' which was set up in 786, would be the oldest Maehyangbi (埋香碑) that we know of. In addition, there is a historical significance in that the Maehyangbi (埋香碑) is proven in the record of Dongguk-myungsanggi (東國名山記), a document from the late Joseon period.

In order to select excellent cross parents for development new cultivar of low temperature tolerant, combining ability was conducted by 24 cross combinations obtained from crosses between 'Dahong', 'Gamhong', 'Maehyang', 'Seolhyang' as seed parents and 'Dahong', 'Gamhong', 'Maehyang', 'Sugyeong', 'Sunhong', 'Wongyo 3111' as pollen parents. The results showed that two cultivars of 'Dahong', 'Gamhong' were not suitable for seed parents. Because average fruit weight in case of 'Dahong' as a seed parent was the tendency to become the smallest in total cross combinations, survival ratio in case of 'Gamhong' as a seed parent was the lowest in total cross combinations. And fruit hardness in case of 'Sunhong' as a pollen parent was the tendency to low, incidence of malformed fruit in case of 'Sugyeong' as a pollen parent was the tendency to be increased. Therefore, two cultivars of 'Sunhong', 'Sugyeong' was also not suitable for pollen parents. But In case of 'Maehyang' and 'Seolhyang' as seed parents, germination percent and survival rate were relatively higher than other seed parents, fruit quality and yield had also excellent. Therefore, there could be selected to 'Maehyang' and 'Seolhyang' as seed parents and 'Maehyang', 'Seolhyang', 'Wongyo3111' as pollen parents. Especially, the crosses 'Maehyang' × 'Seolhyang', 'Seolhyang' × 'Maehyang', 'Seolhyang' × 'Wongyo3111' were suitable for cross combination for development new cultivar of low temperature tolerant to be demonstrated the excellence as cross parents in sugar contents, fruit weight, fruit hardness and yield.

This experiment was performed to determine the concentration of coconut water that is most effective in promoting the growth of 'Maehyang' strawberry in tissue culture. Cultivars in this experiment consisted of 'Maehyang' grown in the presence of 0, 20, 40, 60, 80, 100 ml·L^-1 of coconut water which was added to a medium mixed with BA 0.5 mg·L^-1 and IBA 0.1 mg·L^-1. Morphological variation tests and SSR detection with coconut water were conducted to determine variations in proliferation. The proliferation rate of 'Maehyang' strawberry improved with the coconut water treatment compared to non-treatment. In particular, the proliferation rate with 100 ml·L^-1 coconut water treatment increased by about 4 times. When 'Maeyang' was treated with 100 ml·L^-1 of coconut water, two morphological variants occurred without genetic variation. Therefore, the results suggest that 100 ml·L^-1 of coconut water can be used to mass-produce "Maeyang" strawberry without causing genetic variations.

The occurrence of Fusarium wilt in strawberry fields in Korea was assessed from 2001 to 2003. Fusarium wilt was found from June to August in nursery beds, from September to October after planting in production beds, and from January to March during harvesting period. The symptoms were root rots, discolored vascular tissue in the crown and deformation and yellowing of central leaflets. The disease occurred in up to 30% of plants in 37 of 214 fields surveyed. Fusarium wilt occurred from cvs. ‘Dochiodome’, ‘Maehyang’, ‘Redpearl’, ‘Samaberry ’ and ‘Akihime’ and more severe from cvs. ‘Samaberry’, ‘Maehyang’ and ‘Dochiodome’. Infested soils had high salt concentrations, high nitrogen, phosphate concentrations and low pH. The results of pathogenicity test showed that Fo47 and Fo79 isolated from cvs. ‘Dochiodome’ and ‘Samaberry’ were strong pathogenic to all of four cultivars, and ‘Dochiodome’, ‘Redpearl’, ‘Maehyang’ were relatively susceptible to the all isolates.

In order to select excellent cross parents in strawberry breeding, 11 varieties were self-pollinated and tested their progenies. Among the 11 varieties, 'Akihime', 'Maehyang' and 'Seolhyang' showed superior in plant vigor, disease resistance and yield. Combining ability was tested using 15 progenies obtained from crosses between 3 selected varieties as seed parents and 5 varieties as pollen parents. Plant vigor was the strongest when 'Akihime' was used as a seed parent while ripening time tended to the fastest when 'Seolhyang' as a seed parent. Average fruit weight of the crosses 'Seolhyang' ${\times}$ 'Tochiotome', 'Seolhyang' ${\times}$ 'Geumhyang', 'Seolhyang' ${\times}$ 'Wongyo 3111' and 'Akihime' ${\times}$ 'Wongyo 3111' were above 18 g for marketable fruits. Fruit hardness was superior at crosses of 'Maehyang' as a seed parents to other crosses combinations, especially 'Maehyang' ${\times}$ 'Tochiotome'. Soluble solid contents (SSC) was not significantly different among cross combinations. The best cross combination for marketable yield was 'Akihime' ${\times}$ 'Wongyo 3111', followed by 'Seolhyang' ${\times}$ 'Geumhyang', 'Maehyang' ${\times}$ 'Geumhyang', 'Akihime' ${\times}$ 'Tochiotome', in order.

The fruit flesh of four Prunus mume cultivated varieties, P. mume 'Nanko', P. mume 'Viridicalyx', P. mume 'Baigo', P. mume var, microcarpa 'Koshusaisho' Siebold & Zuccarni, were ground and extracted with ethyl acetate and their chemical components were analyzed by GC/MS-SIM. In the ten compounds which was used fer the calibration, maleic anhydride, citraconic anhydride, 5-hydroxymethylfurfural, vanillin, linoleic acid, ethyl linoleate, and squalene were determined in all the four cultivated varieties. However, palmitic acid was detected only in P. mume var. microcarpa 'Koshusaisho'. Isopropyl palmitate was found only in P. mume 'Baigo' and var, microcarpa 'Koshusaisho', while stearic acid was determined in P. mume 'Nanko', 'Viridicalyx', and var, microcarpa 'Koshusaisho'. In the variation of quantities, maleic anhydride was contained 245.4, 153.6, 20.1, and 2.7 ppm in P. mume 'Baigo', 'Nanko', var. microcarpa 'Koshusaisho', and 'Viridicalyx', respectively. Citraconic anhydride was also contained 637.4, 543.1, 150.7, and 38.7 ppm in P. mume 'Baigo', 'Nanko', var. microcarpa 'Koshusaisho', and 'Viridicalyx', respectively. The amounts of stearic acid were 105.5, 64.4, and 32.3 ppm in P. mume var. microcarpa 'Koshusaisho', 'Viridicalyx', and 'Nanko', respectively. Squalene was found in amounts of 7.6, 1.7, 1.0, and 0.5 ppm in P. mume var. microcarpa 'Koshusaisho', 'Baigo', 'Nanko', and 'Viridicalyx', respectively. The amounts of other minor compounds also were varied in the P. mume cultivated varieties.

This study was carried out to investigate the influence of copper concentrations in fertilizer solution on the growth of and nutrient uptake by domestically bred strawberries. The characterization of toxicity symptoms as well as tissue analyses based on dry weight of above ground tissue were also conducted to determine the threshold levels in plants when toxicity developed in copper. The dry weights of the above ground tissue were not significantly different among the treatments of 0.25 mM to 1.0 mM in 'Keumhyang' and 'Maehyang' strawberries and that of 0.25 mM to 3.0 mM in 'Seolhyang' strawberry. This indicates that the 'Seolhyang' strawberry is more tolerant to copper toxicity than 'Keumhyang' or 'Maehyang' strawberries. Application of copper at high concentrations resulted in severe toxicity such as death of extensive areas of leaves. The lower leaves became yellow and die rapidly as the symptoms spread up the plants. The leaf blades and petioles died back to the crown and hang on by mechanical attachment. Symptoms of copper toxicity in lower leaves developed as browning on leaf margins and in patches between leaf veins that became necrotic. The elevation of copper concentrations in fertilizer solution did not influence the tissue phosphorus, potassium, calcium, and magnesium contents based on the dry weight of the above ground tissue. The tissue copper contents increased lineally as the copper concentrations in fertilizer solution were elevated. But the tissue iron, manganese and boron contents were not influenced by the concentrations. When the concentration of copper at which growth of a plant is retarded by 10% is regarded as threshold level, the copper contents based on dry weight of above ground plant tissue should be lower than 71.4, 57.9 and 74.8 $mg{\cdot}kg^{-1}$ in 'Keumhyang', 'Maehyang' and 'Seolhyang' strawberries, respectively. The symptom characterization and established threshold level in copper toxicity would help growers to prevent the reduction of crop growth and yield in 'Seolhyang' strawberry cultivation.

The experiment was conducted to investigate the effect of nitrogen and potassium sources on growth and yield of strawberry 'Seolhyang' and 'Maehyang' in fertigation culture. The plant fresh and dry weight were higher in urea + potassium sulfate and ammonium sulfate + potassium sulfate as nitrogen and potassium sources than others in both varieties. But there were no significant difference among nitrogen and potassium sources in other growth characteristics, such as plant height, no. of leaf, crown diameter etc. Also, the marketable yield of fruit were higher in urea + potassium sulfate and ammonium sulfate + potassium sulfate in 'Seolhyang' than other treatments. 'Maehyang' was better in both treatments but there was no significant difference. The fruit qualities, such as total soluble solid, hardness, acidity, vitamin C content were not significant difference among the treatments. The acidity of soil was tended to decrease but EC was tended to increase highly in ammonium sulfate treatments as a nitrogen source. As above results, the urea and potassium sulfate were recommended as nitrogen and potassium sources for the fertigation culture of strawberry 'Seolhyang' and 'Maehyang'.

A study was conducted to examine the effect of precooling (2, 4, or $8^{\circ}C$) and storage (4, 8, or $10^{\circ}C$) temperatures on the storage life of 'Maehyang' and 'Soogyeong' strawberries for export. Fruits at a 70% ripe stage were harvested from a commercial greenhouse in Jinju on March 16, 2010. Fruits were precooled by a forced draft cooling for 3 hours, transported for about 30 minutes to a lab., and then stored. For precooling, small precoolers set in the farm were used. During storage, fruits were examined for their changes in weight, hardness, color (hunter value), soluble solid content, incidence of gray mold (Botrytis cinerea), and marketability at a two days interval from March 16 to March 30. In both cultivars, hardness, sugar content, and hunter value were higher in 'Soogyeong' than 'Maehyang'. The greatest hardness and soluble solid content were obtained after storage at $4^{\circ}C$ in both cultivars. As the ripening stage progressed, hardness and soluble solid content decreased. Also, fresh weight decreased during storage at all temperatures. Gray mold was the greatest at $10^{\circ}C$ storage temperature. The results indicate that effectiveness for keeping the freshness was best achieved by precooling at $2^{\circ}C$ and storage at $4^{\circ}C$ in both cultivars.
