In Korea, consumer demand for seedless grapes with high quality and large berries is increasing. Although a lot of effort into introducing European stenospermocarpic grape cultivars in Korea has been made, it did not work because they were not adaptable to growth conditions in Korea. In Korea, most seedless grapes are currently produced by applying plant growth regulators twice, using seeded grape cultivars such as Kyoho and Shine Muscat. Because this method is time-consuming and labor intensive, it is becoming more important to breed and introduce seedless grape cultivars that can reduce labor and time. The characteristics of parthenocarpy, stenospermocarpy,

Vitis amurensis is a member of the family Vitaceae and is found in China, Japan, and Korea (Venuti et al., 2013). Several researchers have reported that it has high disease resistance and freezing tolerance (Jiao et al., 2015; Liu and Li, 2013) and contains many health-promoting compounds such as anthocyanin and resveratrol (He et al., 2015). Therefore, although V. amurensis has received great attention in Korea (Park et al., 2015), it has been mainly used for making processed products because of its generally low fruit quality (

The present study aimed to assess the physical and psychological health benefits of a 15-session gardening intervention in elderly women and to investigate satisfaction of the gardening intervention. Fifty elderly women (age >70 years) at two senior community centers located in Seoul, South Korea, were selected to participate in this study. Twenty-four elderly women at senior community center “A” participated in a twice-weekly gardening intervention (≈50 minutes per session) during the period Sept. to Nov. 2015; 26 elderly women at senior community center “B” comprised a control group. At the completion of the 15-session gardening intervention, physical health parameters such as body composition, physical functional ability, and hand function ability were assessed in both groups. Additionally, psychological health conditions, such as cognitive ability, depression, and sociality, were assessed. The elderly women also answered a questionnaire to assess the amount of physical activity experienced during daily life. Elderly women in the gardening intervention group exhibited significantly improved muscle mass, aerobic endurance, hand dexterity, cognitive ability, and decreased waist circumference (P < 0.05). In contrast, significantly decreased muscle mass and agility and increased depression were observed in the control group (P < 0.05). Moreover, elderly women in the gardening intervention group reported a significantly higher amount of daily physical activity compared with those in the control group (P < 0.05). Additionally, 95.8% of elderly women in the gardening intervention group reported of being very satisfied with the gardening intervention. In conclusion, the gardening intervention maintained and improved the physical and psychological health of elderly women at a senior community center, whereas elderly women in the control group experienced age-related reduced physical and psychological health conditions. More studies are needed to evaluate the effects of a gardening intervention in a larger population of elderly women; in addition, a longer intervention period would provide a better measure of health in elderly women.

Because of the success of the grape cultivar Shine Muscat in Korea, consumer interest in high-quality seedless grapes has significantly increased (Kim et al., 2021). In Korea, most seedless grapes are currently produced by treating genetically seeded grape cultivars, such as Shine Muscat and Kyoho, with plant growth regulators before and after flowering. Unfortunately, although the method effectively induces production of seedless fruits, the standardization of fruit quality is difficult to achieve because it is not easy to set an optimal treatment time and concentration of the growth regulator. Furthermore, the additional labor required, which accounts for a

In Korea, ‘Campbell Early’, ‘Shine Muscat’, and ‘Kyoho’ account for more than 90% of the Korean grape cultivation area (Kim et al., 2021). As a result, the supply of grapes in the Korean market is excessive during a certain period. Consequently, it is difficult to avoid a reduction in the wholesale price, and the opportunity for consumers to experience other grape cultivars becomes limited. In the current scenario, in which imports are occurring rapidly following the recent implementation of the free-trade agreement with Chile and the United States, it is necessary to cultivate various high-quality grape cultivars to

The objective of this study was to investigate the effects of a gardening intervention as a physical activity in women aged over 70 years. Twenty-one women aged over 70 years were recruited from the community in Seoul, South Korea. Eleven subjects at a senior community center participated in a 15-session gardening program (twice a week, average 50 minutes per session) from Sept. to Nov. 2015. The rest of the subjects who were recruited from another senior community center acted as the control group. Blood lipid profiles, blood pressure, inflammation in peripheral-blood mononuclear cells (PBMC), and oxidative stress were assessed by a blood test before and after the 15-session gardening intervention. The results showed that the subjects in the gardening intervention as a low- to moderate-physical activity had a significant improvement in their high-density lipoprotein (HDL) level, systolic and diastolic blood pressures, and the variables related to immunity such as tumor necrosis factor-α (TNF-α) for inflammation in blood and receptor for advanced glycation end products (RAGE) expression for oxidative stress. The results of this study suggested that the 15-session gardening intervention as a low- to moderate-physical activity led to positive effects on the blood lipid profiles, blood pressure, level of inflammatory markers in blood, and oxidative stress of women aged over 70 years.
