The effects of Japanese apricot(Prunus mume Sieb. et Zucc.) flesh on baking properties of white breads were investigated by evaluation of specific loaf volume, pH, acidity, rheological property, color and sensory quality. Bread was processed by adding 4.7%, 9.4%, 14.1% and 18.8% of Japanese apricot flesh to basic formulation. The compositions of Japanese apricot flesh were 88.19% moisture, 0.45% crude ash, 4.10% dietary fiber, 4.04% citric acid and 0.41% total sugars. The specific loaf volume of the breads was decreased from 3.274mL/g to 1.857mL/g as Japanese apricot flesh contents increased from 0% to 18.8%. The pH of the breads decreased but the acidity of those increased as the percentage of Japanese apricot flesh to wheat flour increased. Lightness(L value) of the breads decreased by the addition of Japanese apricot flesh, while yellowness(b value) and redness(a value) increased. Texture measurement showed that springiness, cohesiveness and resilience decreased with increase of Japanese apricot flesh contents. While, hardness, gumminess and chewiness were the lowest in the bread with 9.4% Japanese apricot flesh, and increased in the bread with 4.7%, 14.1% and 18.8% Japanese apricot flesh contents. In sensory evaluation, the highest sensory scores for flavor, taste, aftertaste and overall acceptability were obtained when Japanese apricot flesh content was 4.7%, and softness and chewiness was the best when 9.4% of Japanese apricot flesh was added. The moisture content of the breads containing Japanese apricot flesh was higher than that of the control to add no flesh during storage at $25^{\circ}C$. Based on physical, rheological and sensory evaluation, addition of 4.7{\sim}9.4% Japanese apricot flesh suggested to be acceptable for processing bread.

Japanese apricot (Prunus mume Sieb. et Zucc.) is the national symbol and was once the most important temperate fruit crop in Taiwan. Fruiting cultivars were originally introduced from southern China but commercial production was not significant until the 1970s. Currently 6,400 ha of Japanese apricot orchards distribute on shallow mountain hills in the central and the southern part of the island. Taiwanese commercial fruiting cultivars are plausibly chance seedlings or sports from the early introduction and are very low chilling required for budbreak. Ornamental cultivars have been mainly introduced from Japan but cultivations have been limited in high altitude area due to their high chilling requirement. In 2009, Taiwan Agricultural Research Institute's breeding program released the first low chill ornamental cultivar 'Tainung No.2' with a great ornamental potential in subtropical regions. Cultivation and production of Japanese apricot fruit in Taiwan continue to dwindle due to the declining Japanese market share. Ongoing industry transformation to increase domestic consumption and consumer's interest will sustain the future of Japanese apricot in Taiwan.

To investigate Phomopsis species causing fruit decays of Japanese apricot, apple and kiwifruit, we collected diseased fruits from the fruit markets in 1995 and 1996 respectively. Phomopsis mali Roberts was identified based on cultural characteristics, morphological aspects and pathogenicity. There were no remarkable differences with respect to $\alpha$ and $\beta$ conidia, growth rates and colony characters among the isolates from Japanese apricot, apple and kiwifruit. The pathogens grew more than 70 mm on potato dextrose agar in 5 days at $25^{\circ}C$. The agar was slightly discolored by the production of a reddish purple pigment under the light at $25^{\circ}C$ and 3$0^{\circ}C$ respectively. Only $\alpha$ spores of the different isolates of P. mali were formed at 15$^{\circ}C$ and $\beta$ spores were mainly produced at 3$0^{\circ}C$, but and $\alpha$ and $\beta$ spores were produced in approximately equal numbers at 2$0^{\circ}C$ and $25^{\circ}C$. Pycnidia were a few under the dark condition but were abundant at wide range of 15~3$0^{\circ}C$ under near ultra violet illumination. Conidia were two types : $\alpha$ spores were unicellar, fusoid, hyaline and biguttulate, whereas $\beta$ sores were unicellar, acicular to filiform, straight or hooked and hyaline. An ascigerous stage was not formed in cultures or in nature. Isolates of Phomopsis mali from japanese apricot, apple and kiwifruit could infect fruits of apple, pear, apricot, Japanese apricot and kiwifruit. There were some differences in pathogenicity depending on stocks of fruit crops tested.

This study was conducted to investigate the applicability of gamma irradiation for improving the quality of paprika and Japanese apricot extract-treated nitrite free pork jerky. Pork jerky was gamma-irradiated at 0, 3, 5, 7 and 10 kGy and physiochemical properties such as proximate composition, 2-thiobarbituric acid (TBARS) values, color stability, texture, and sensory property were then evaluated. The results showed that the treatment of paprika and Japanese apricot extract to the pork jerky increased Hunter color value and texture property and at the same time decreased TBARS values. When gamma irradiated, natural pigment extract-treated pork jerky did not produce any change in its proximate composition (moisture, crude protein, crude lipid contents), and TBARS values. However, the redness (a-value) of pork jerky increased as the irradiation dose increased, whereas shear force of pork jerky was decreased. Sensory result showed that gamma irradiation induced to decrease the sensory scores. Therefore, these results suggest that gamma irradiation and the addition of paprika and Japanese apricot extracts could be an effective mean to improve color and texture of restructured pork jerky without use of nitrite.

Scabs caused by Venturia carpophila greatly reduce the quality of the fruits of the Japanese apricot (Prunus mume) when the disease is not properly managed. The disease produces a superficial blemish that is unlikely to affect the overall yield of processed fruit, but reduce the value of fruit intended for the fresh market. Incidence rates of scab at sprayed and unsprayed orchards range from 0% to 21.5% and from 30.2% to 100%, respectively, in the major cultivation regions of Jeonnam Province during the growing season of 2009. The trends in disease progress were quite similar, regardless of regions, and cultivar Namgo was relatively less damaged by scab compared to cultivar Cheonmae among the tested Japanese apricot cultivars. The fruits on branches 1.5 m above the infected Japanese apricot trees and the stem-end parts of the infected fruits were more severely damaged by scabs, possibly because of rain and run-off facilitate dissemination of conidia of V. carpophila and subsequent infection of the fruits or branches. The conidia of V. carpophila were dispersed from March 24 to April 26 in 2010, and more conidia were dispersed from 2-year-old branches than 1-year-old branches. Since the control efficacies were higher than 90% after more than two applications of Trifloxystrobin WG at 10-day-intervals from mid April, it is that effective fungicides be applied at least two times at 10-day-intervals from the middle of April to manage scabs of Japanese apricot in orchards.

Twenty-three plants of Japanese apricot (Prunus mume) were collected from several sites around Mountains JIRI in Korea. Japanese apricots having the different morphological features were evenly distributed in the groups made from the cluster analysis, indicating no geographic distributions but artificial vegetations in Korea. Japanese apricots were, as based on the PCR-RAPD techniques, clustered into the three groups; a group (prototype) having the five white petals with the five red sepals, a group (green type) having the five white petals with the five green sepals, and a group (hybrid type) having the more than five red petals with various colored sepals. The prototype apricots showed higher toxicities than other type apricot against bacteria and production of less compounds in TLC plates. The polypetal types of Japanes apricot were related to those of p. armebiaca in the characteristics of seed (the ruggedness), but also to be closed to those of p. armebiaca in PCR-RAPD analysis. The cluster analysis of the twenty three apricots and its related species calculated from the two primers were shown to distinguish relationships of cultivars within species, or of individual plants within cultivars, but also to display the two overlapping bands resulted from PCR-RAPD technique.
