Paphiopedilum Clair de Lune ‘Edgard Van Belle’, an excellent Maudiae-type hybrid that has been propagated by artificial division for a long time. We studied its flower bud initiation, development of floral organs, and flowering habits with a view to providing information for flowering control and efficient commercial production. According to our research, the flower bud initiation phase of this cultivar begins in February every year, and 80% of the plants completed sepal primordium differentiation in March, The flower bud differentiation lasts for 6 to 7 months, until flowering in August. Within 1 to 3 months after flower bud differentiation, all tested plants differentiated lateral buds. After 5 to 6 months, the new, aboveground vegetative shoots reached their maximum growth, with an average plant height of 20 cm, five leaves, and a shoot dry weight of more than 3 g. From February to April of the following year, a new cycle of flower development and vegetative growth began. In addition, this cultivar was notably sensitivity to high ambient temperature during the late phase of flower development, with a flower bud drop rate as high as 33.3% under average day/night temperatures of 29.0/26.5 °C.
Nature and health researchers have often suggested that nature induces better psychological and physical health responses than urban environments, especially with healthy ecosystems in nature. However, research that has empirically documented the daily benefits of physical and psychological health in rural landscapes is scarce. This study explores how rural landscapes could provide better health benefits than the built environment in daily life. The research involved on-site data collection with a set of psychological indicators (e.g., restorativeness, preference, emotion) and physical indicators (e.g., brain waves, heart rate) to compare the rural and the built environments. A total of 169 subjects took part in the study. We analyzed health indicators through analysis of variance to show the difference in water landscapes in rural areas relative to the built environment after the participants experienced the environments. The results showed that subjects could release stress and felt a greater sense of restorativeness, pleasure, and arousal in rural areas than in the built environment. Subjects preferred the rural landscape more than the built environment. To conclude, this study explains the rural landscape and its health-related benefits in Taiwan.
