  Title The ecological significance of phenology in four different tree species: effects of light and temperature on bud burst Type Journal Article
  Year (down) 2011 Publication International Journal of Biometeorology Abbreviated Journal Int J Biometeorol  
  Volume 55 Issue 5 Pages 711-721  
  Keywords Plants  
  Abstract The process of adaptation is the result of stabilising selection caused by two opposite forces: protection against an unfavourable season (survival adaptation), and effective use of growing resources (capacity adaptation). As plant species have evolved different life strategies based on different trade offs between survival and capacity adaptations, different phenological responses are also expected among species. The aim of this study was to compare budburst responses of two opportunistic species (Betula pubescens, and Salix x smithiana) with that of two long-lived, late successional species (Fagus sylvatica and Tilia cordata) and consider their ecological significance. Thus, we performed a series of experiments whereby temperature and photoperiod were manipulated during dormancy. T. cordata and F. sylvatica showed low rates of budburst, high chilling requirements and responsiveness to light intensity, while B. pubescens and S. x smithiana had high rates of budburst, low chilling requirements and were not affected by light intensity. In addition, budburst in B. pubescens and S. x smithiana was more responsive to high forcing temperatures than in T. cordata and F. sylvatica. These results suggest that the timing of growth onset in B. pubescens and S. x smithiana (opportunistic) is regulated through a less conservative mechanism than in T. cordata and F. sylvatica (long-lived, late successional), and that these species trade a higher risk of frost damage for the opportunity of vigorous growth at the beginning of spring, before canopy closure. This information should be considered when assessing the impacts of climate change on vegetation or developing phenological models.

  Title Effect of Night Illumination on Growth and Yield of Soybean Type Journal Article
  Year (down) 2009 Publication Journal of Taiwan Agricultural Research Abbreviated Journal J. of Taiwan Agricultural Res.  
  Volume Issue Pages  
  Keywords Plants; soybeans; Taiwan  
  Abstract To evaluate the potential of soybean as a crop for bio-fuel in Taiwan, field experiments were conducted in 2006 across the island, using an Australian variety ‘Leichardt’. This study was one of the field experiments at Hemei Township, Changhua County. Soybean was seeded by hand-spreading in the fall of 2006 and harvested in 2007. Results showed that seeding of soybean by hand-spreading affected uniformity of seed germination and caused high variations in yield in this field. Seed yield of soybean reached 770 kg ha-1 under good pest management and disease control. The study also showed that night illumination is an important factor affecting growth and yield of soybean. Plants growing near the roadside (within 10–20 m) were exposed to the night light, resulting in prolonged vegetative growth and delayed blossom period for about 1 to 4 weeks. Therefore, such plants suffered from poor pod filling due to low temperature stress at reproduction stage and delayed the harvest period for about 6 weeks. Nevertheless, seed yield of soybean plants exposed to the night illumination reached 1000 kg ha-1, which was slightly higher than soybean plants without exposuring to the night illumination.

  Title Supplementary Ultraviolet Radiation B Together with Blue Light at Night Increased Quercetin Content and Flavonol Synthase Gene Expression in Leaf Lettuce (Lactuca sativa L.) Type Journal Article
  Year (down) 2008 Publication Environment Control in Biology Abbreviated Journal Environ. Control Biol.  
  Volume 46 Issue 1 Pages 1-11  
  Keywords Plants  
  Abstract Establishment of an effective supplementary lighting procedure is necessary to increase the value of leaf lettuce grown using a hydroponic method involving a low production cost. In leaf lettuce extracts, quercetin, one of the flavonoids, was isolated and identified. It was investigated that quercetin has important functions that can be used as a dietary supplement. Flavonol synthase (FLS) is a key enzyme involved in quercetin biosynthesis, catalyzes the conversion of dihydroquercetin to quercetin. Therefore, we determined the sequence of the flavonol synthase gene (FLS) in red leaf lettuce. We harvested leaf lettuce grown using supplementary light sources, such as ultraviolet radiation B (UV-B), ultraviolet radiation A, blue, and red lamps during the night. It is noteworthy that FLS expression and the quercetin content were particularly increased to a greater extent in young leaves than in mature leaves when UV-B and blue light were used simultaneously at night. We suggest that UV-B with blue light is used simultaneously at night for producing leaf lettuce with high quercetin content.
