Purpose: The study was done to examine the development and effects of horticulture therapy on quality of sleep and immune function in patients in hospice units. Methods: The participants in this study were hospice patients in D hospital in D city. Thirty hospice patients were assigned to the experimental group, thirty to the control group. Data were collected from April 29 to July 26, 2009. The horticulture therapy program consisted of indoor and outdoor horticultural activities. The horticulture therapy was conducted for 30 minutes, 6 times a week for 3 weeks (a total 18 times). Measures were quality of sleep, and immune function by serum T-cell, NK-cell count. Data were analyzed using descriptive statistics, chi-square test and t-test with SPSS/WIN 13.0 version. Results: Patients in the experimental group receiving horticulture therapy had a significant difference in changes in the quality of sleep compared to the control group. There were also a significant difference in changes in the immune function (serum T cell and serum NK cell) between the experimental group and control group. Conclusion: The study results indicate that horticulture therapy developed for hospice patients is an effective, palliative intervention program to improve the quality of sleep and immune function of hospice patients.

This study was conducted to determine the optimum conditions for the treatment of polyamine to promote pollen germination and improve the fruiting rate by overcoming fertilization defects in low-temperature strawberry cultivation. The optimum temperature for pollen germination of strawberries was 30 ℃ for Seolhyang and 25 ℃ for Maehyang, and Seolhyang had a higher pollen germination rate than that of Maehyang. The addition of polyamines, namely spermine and putrescine to the medium improved the pollen germination rate and spermine treatment showed a better effect than putrescine treatment. The proper polyamine type and treatment concentration for enhancing the potency of pollen germination was 500 μM of spermine for both Seolhyang and Maehyang, which improved the pollen germination rate by 19-23% compared with that of the control. However, combined treatment of spermine and putrescine, resulted in a lower germination rate lower than that of the single treatment. Our results indicated that the treatment of polyamines during flowering in protected cultivation of strawberrise can improve the fruiting rate by overcoming the problem of poor pollen germination due to low temperature.

The purpose of this study was to investigate the effects of defoliation treatment on the growth and yield of strawberries. There was a remarkable growth in the above-ground part and root of untreated strawberry plants possibly due to higher amount of photosynthesis, while overall plant growth was suppressed as the level of defoliation treatment increased. In both the "Seolhyang" and "Maehyang" cultivars examined, defoliation treatment resulted in small fruits and a low number of fruits per plant. Notably, 50% defoliation significantly reduced the number of fruits per plant to 8.2, compared to 13.8 in untreated plants. Defoliation treatment also negatively influenced the fruit quality including color, sugar content, and solid-acid rate. However, no significant changes in fruit firmness was observed in either cultivar. Therefore, retaining enough leaves without defoliation treatment can be important to increasing fruit yield, producing high quality fruits and saving labor required for defoliation.
