DESCRIPTION:PhD Oral Defence of Bo-Sen Wu\, Bioresource Engineering\n\nLigh
 t emitting diode (LED) technology benefits the horticultural industry in n
 umerous ways. However\, questions surrounding LED performance for plant cu
 ltivation (photosynthetic and photomorphogenic responses)\, reliability in
  operation\, and eye safety have not yet been determined. This dissertatio
 n addresses these questions from the perspective of an LED user and the pl
 ant\, with an emphasis on the spectral quality of photosynthesis with 1-nm
  resolution. Findings from this study demonstrated the spectral photosynth
 etic curves had two distinct peaks at 430 nm and 650 nm\, and shoulders at
  480 nm and 595 nm\, which implied that major pigments might not be just u
 sed to funnel light energy in photosynthetic machinery. Furthermore\, the 
 photodamage efficiency of photosystem II (PSII) provides indirect evidence
  of a link between 595-nm light and oxygen-evolving complex (OEC) involvem
 ent in photosynthesis\, suggesting that OEC initiates the use of photosynt
 hetic machinery in the presence of 595-nm light. Together\, these data imp
 ly that the current understanding of photosynthetic activity in plants\, p
 reviously based on extracted pigment data\, is not completely accurate\, s
 etting precedence for future experiments aimed at understanding the insigh
 t of photosynthesis.\n\nEveryone in the 9IÖÆ×÷³§Ãâ·Ñ community is welcome to att
 end a PhD Oral Defence. Please join us in celebrating the accomplishments 
 of our PhD candidates.\n
