Genetic diversity and relationship in the related plant taxa is a prerequisite for crop improvement. Amplified fragment length polymorphism (AFLP) fingerprinting is one of the powerful and widely used tools, which has found wide spread application in numerous studies ranging from genetic mapping to diversity surveys in plants and other organisms. Genome relationship among diploid and allotetraploid Brassica taxa, and between interspecific hybrid or intergeneric hybrid and their parental species were investigated using AFLP display. The two primer pairs for AFLP reactions and seven EcoRI (+2) and M5eI (+3) primer combinations were used in the measurement of genetic relationships. Genetic similarities among nine accessions were estimated by Nei’s distance equation, and cluster analysis was performed using the unweighed pair group method (UPGMA) in the computer program NTSYS-pc. One intergeneric hybrid between Brassica and Raphanus showed 2n=4x=38 chromosomes, of which Raphanus chromosome segment were translocated with B. rapa chromosome.

This study was conducted to develop an effective production of mechanization system for garlics, in which the non-cloved bulbs could be used as a seed bulb. Non-cloved and cloved bulbs produced from the bulbils were compared in their field performance according to planting methods with those cloves produced conventionally. The most desirable planting depth was 8㎝ using 3.5g ‘Namdo’ or 4.5g ‘Danyang’ of non-cloved as seed garlic for producing high quality garlic. In the planting angle methods, non-cloved garlic showed much yield and higher survival late than cloves. The survival late of seed garlics in the field was decreased as the planting angle increased.

A temporal relationship between changes in soluble sugar content and the activity of their hydrolytic enzymes of netted melon fruit during development and senescence was investigated. Analysis for the sugars content of the commercial cultivars ‘Sunpower’ and ‘MVP’ revealed the major soluble sugars in pulp tissue of melon fruit were sucrose, glucose, fructose. In addition, raffinose and stachyose were also found during the ontogeny of the fruit. During a rapid fruit growth, up to 30 days after pollination (DAP), the amount of sucrose, raffinose, and stachyose remained substantially low, ranging from 0.0 to 0.1 miligram per gram fresh weight. However, the level of fructose and glucose maintained relatively high in the tissue, ranging 10 to 25 miligram per gram fresh weight. In accordance with this result, the activity of both acidic and neutral invertase showed a fairly high upto 20 DAP, and followed by a sharp decrease in the activities during maturation and senescence of the fruit. A similar pattern of the change in the activity of both acidic and neutral ɑ-galactosidase also observed during the fruit development and senescence. Concomitantly to this, there was a rapid increase in the pool size of sucrose, raffinose, stachyose, substantiating an increase in soluble sugar contents in the aging fruit. From the present study, it was suggested that in netted melon fruit both invertase and ɑ-galactosidase play an important role in regulating the accumulation of the soluble sugars, which, in turn leads to an increase sweetness of the fruit.

This study was conducted to evaluate the suitable training method under low plastic film greenhouse cultivation on sweet pepper in highland. Training treatments were upright training, inclination training, upright ⇒ inclination training (Jun. 8), and upright ⇒ inclination training (Aug. 21). In the early growth stage, lateral shoots of plants of inclination training treatments were strong and higher than those of others. Light transmission ratio of upright training around low leaves was 37% which was higher than 14% of inclination training. The fruit setting ratio of upright training was the highest by 41% out of all. The number of fruits per plant of the upright training was 18.1, which showed 5.2 more than that at inclination training. The marketable yield of the upright training was 109 tonㆍha⁻¹ which showed 43% higher than inclination training. Labor time of inclination training was 7,785 hrㆍha⁻¹ which showed 1,185 hrㆍha⁻¹ more than that of upright training. Therefore, the upright training was recommended for the suitable training method to marketable yield and quality improvement under low plastic film greenhouse cultivation on sweet pepper in highland.

Korean Journal of Horticultural Science and Technology, volume 25, issue 2, 2007, Pages 103~109
For the analysis of genetic relationship among genetic resources of Sedum sarmentosum, the morphological characteristics were investigated in 31 Korean local strains, and cluster analysis using SAS program (version 8.2) was conducted based on the morphological data. Thirty-one local strains were classified into two groups by the cluster analysis based on growth and flowering characteristics. Group Ⅰ included most of local strains with flowering characteristic, and Group Ⅱ included non-flowering, ‘Wanju’ and ‘Gunsan’ local strains. Group Ⅰ was divided into two subgroups. Four local strains with flourishing growth and flowering characteristics, ‘Keumsan’, ‘Bucheon’, ‘Pocheon’, and ‘Yongin’ were contained into the subgroup Ⅰ-1, and others were belonged into the subgroup Ⅰ-2. Among 31 local strains, ‘Wanju’ and ‘Gunsan’ local strains with good growth and non-flowering characteristics were favorable as edible resources. It was desirable as the resources of garden plant and ground cover plant that ‘Keumsan’, ‘Bucheon’, ‘Pocheon’, and ‘Yongin’ local strains showed the characteristics of slender stem and leaf, long flower stock, and flourishing flowering.

The rate of bitter pit incidence and the mineral contents of fruit in ‘Gamhong’ apple fruit were investigated according to the controls of three different crop loads. The rate of bitter pit incidence tended to be higher and more frequent when the crop loads were getting less. As the crop loads became less, the fruit size became larger and contained the higher soluble solids and acid contents, but firmness got lower. As the crop load increased, however, the Ca concentration of the fruit was higher, and the concentrations of K and Mg were lower in the peel and the outer cortex. The K/Ca, the Mg/Ca, and the (K+Mg)/Ca of the peel and the outer cortex were higher as the crop load got less, but any consistent tendency was not observed in the inner cortex and the core.

Astringent type persimmon varieties have been cultivated from ancient times in Korea. In the long cultivation of the persimmon, various local varieties have been developed and cultivated throughout from the central to the Southern area. Therefore, the aim of this study was to reveal genetic relationships of local 22 persimmon varieties, including one Chinese cultivar ‘Damopan’ and four Japanese cultivar ‘Koshuhyakume’, ‘Hirataneanshi’, ‘Saijo’, and ‘Yokono’, using AFLP technique. Total bulk DNA of the persimmon cultivars were amplified with primer combinations based on the sequence of EcoRI and MseI adapters. The eight primer combinations amplified a total of 357 polymorphic fragments. According to AFLP calculated genetic similarities, ‘Godongsi’ and ‘Hakdongsi’ were closely related each other. In addition, ‘Durigam’ and ‘Yokono’ showed close genetic similarity, which were collected from Hamyang in Korea and Japan, respectively. However, Chinese persimmon ‘Dampon’ and ‘Wolhasi’ were poorly related with the other collected varieties.

This study was carried out to inquire the factor related to the development of calyx perpetual fruit, which made fruit shape deformed and fruit quality worse, and to make a cultivation techniques inhibiting it. The changes of tree growth and the development of calyx perpetual fruit were investigated with spur flower types. In twin flower bud, which was heavier and bigger widely, calyx perpetual fruit production was higher than in single flower bud. Especially, calyx perpetual fruit production was more severe in fruits set on sub-flower cluster of twin flower bud. In mineral contents of flower bud, twin flower bud showed higher nitrogen content and lower phosphorous, potassium, calcium content than single flower bud. IAA, t-zeatin and ABA contents in bud from 110 to 7 days after full bloom were higher in twin flower bud than single flower bud. IAA content was increased, t-zeatin content was constant, and ABA content was decreased up to full bloom in both buds. Consequently, the change and difference of plant hormone affects on budding, flowering, further more calyx perpetual fruitlet production.

Relationship between instrumental quality attributes and consumers’ acceptance in ‘Campbell Early’ and ‘Kyoho’ grapes were analyzed to indicate an appropriate instrumental attribute reflecting the changes in overall taste during 4-month refrigerated storage. Relationship between instrumental measurements and sensory ratings were studied through correlation study using 32-or 64-paired data set obtained at one-month intervals during storage. Soluble solids concentration (SSC) was not significantly correlated with sweetness and overall taste. Correlation between titratable acidity (TA) and overall taste was significantly negative in ‘Campbell Early’, while positive in early-harvested ‘Kyoho’ grape. Highly positive correlation was found between flesh firmness and overall taste in early- and late-harvested ‘Campbell Early’ and early-harvested ‘Kyoho’ grape suggesting that flesh firmness can be used as an indicator reflecting the consumer acceptance for grapes during storage. Minimum levels of flesh firmness for acceptable eating quality were 0.44, 0.30, and 0.20 N for early-, late-harvested ‘Campbell Early’ and early-harvested ‘Kyoho’ grapes, respectively. As related to consumer’s eating habits, SSC: TA ratio of free juice seemed to be an appropriate quality factor indicating consumer acceptance for ‘Campbell Early’ grape but not for ‘Kyoho’ grape.

‘Jinhwang’ pear cultivar (Pyrus pyrifolia Nakai) originated from the cross between ‘Danbae’ and ‘Kosui’ to improve the fruit quality of ‘Danbae’ in 1982 at Pear Experiment Station of National Horticultural Research Institute, Rural Development Administration Korea. ‘Jinhwang’ was preliminarily selected in 1994 and named in 2004. The tree habit shows vigorous growth and upright spreading. The genotype of self-incompatibility is inferred to S₃S₄ with abundant pollen grains. Therefore, this cultivar is cross compatible with major cultivars those are ‘Niitaka’, ‘Whasan’, ‘Wonhwang’, and so on in Korea. ‘Jinhwang’ is highly resistant to black leaf spot (Alternaria kikuchiana) in the field condition. The optimum harvesting time in Naju Korea is on September 4th when is the one of the largest pear consuming season of Chuseok holidays and when is 5 days later than that of ‘Wonwhang’. The soft and juicy flesh is rendering good eating quality. Shelf life is about 10 days under the ambient temperature. The fruit skin color is green yellowish brown at normal harvesting time and gradually turns to yellowish brown at full ripening stage. The average of fruit weight is 501 g, and the content of soluble solid is 13.1 °Bx.

Korean Journal of Horticultural Science and Technology, volume 25, issue 2, 2007, Pages 138~144
To investigate the effects of modified atmosphere packaging (MAP) on freshness of ‘Kyoho’ and ‘Campbell Early’ grapes, changes of fruit physiological attributes and respiration and berry abscission in the abscission zone were examined during 60 days of cold storage at 0℃ with 90% relative humidity. Grapes packaged with 0.03㎜ polyethylene film maintained berry firmness, soluble solid content, titratable acidity, and peel L value compared with control treatment. MAP with 0.03㎜ polyethylene film also reduced respiration rate, decay and weight loss. In contrast, antifogging and perforation film (0.20 and 3.14%) accelerated the production of grape respiration, development of decay and berry abscission resulting in loss of marketability after 60 days of cold storage.

In order to investigate the effect of application rate of lead on tree growth, toxicity symptom, and lead accumulation in fruit tree, one year old pear trees were transplanted into plastic container containing sand. Then, pear trees were cultured with nutrient solution containing 1 to 20㎎ㆍL⁻¹ of lead. Elongation of shoot and growth of stem were suppressed and dry weight of whole tree was decrease by elevated lead concentrations. A symptom of lead toxicity did not appear except for growth decrease. When lead level of nutrient solutions was higher than 1㎎ㆍL⁻¹, lead concentration in tissue increased, and the lead concentration in roots was particularly high. Elevated lead concentrations in nutrient solution resulted in increase of lead amounts accumulation in roots but not in leaf, shoot, and stem.

The flowering response of azalea as influenced by forcing dates were investigated. Days to flowering and flowering period showed significant difference by different forcing dates between September and January. Cold damage was observed in ‘Red Beauty’ forced in November and 40% of ‘Red Beauty’ showed cold damage when forced in December and January. In all the test varieties, flowering was once increased and decreased in treatments forced in September, October, and November, while treatments of forcing in December and January showed characteristics of short flowering period and days to flowering all together. The forcing dates of ‘Red Wing’ was on January 26, The forcing dates of ‘Mother’s Day’ and ‘Coral Wing’ was on December 26.

‘Kidachi’ and ‘Sun Smile’, dwarf cultivars and ‘Violet’, tall cultivar of Pharbitis nil were used for plant materials grown under a long day, non-inducing condition of flower bud. Flowering response was examined according to the concentration, frequency, and treatment time of theobroxide. Theobroxide treatment resulted in promoted flowering and increased flower number even though the flowering response was different depending on cultivars. The most effective condition of theobroxide spray for flowering promotion was 5-10 times of 1 mM for ‘Kidachi’ with 2-3 leaves, 5-10 times of 1 mM for ‘Sun Smile’ with 5-6 leaves, and 5 times of 1-2 mM for ‘Violet’ with 5-6 leaves.

The main objectives of this study were to investigate flower bud differentiation and carbohydrate status in tuber during early growth stage in Zantedeschia albomaculata ‘Black Magic’ by soaking tubers into 500 ㎎ㆍL⁻¹ GA₃ solution before planting. As the early growth were promoted by GA₃ treatment so shoot length had a difference from 10 days after planting, therefore, were higher as 11.6㎝ in GA₃ treatment than as 7.4㎝ in control. At 30 days after planting, carbohydrate in tuber existed as 359~464㎎ㆍg⁻¹ DW starch, 49.2~76.8㎎ㆍg⁻¹ DW sucrose, 8.0~10.0㎎ㆍg⁻¹ DW glucose and 9.5~13.9㎎ㆍg⁻¹ DW fructose. Starch content at 30 days after planting in GA₃ treatment and control than at planting were lower 34.8% and 16.7%, respectively. As shoot developed, soluble sugar Content were increased and high in GA₃ treatment, especially. At planting, cell division for vegetative growth in apical bud On tuber were observed actively. Also flower bud differentiation in GA₃ treatment made rapid progress and the percentage of female and male organ at 20 days and 30 days after planting reached 60% and 80%, respectively.
