Blue Light Monochromatic Irradiation for 12 Hours in Lighting Pattern with Combinations of Blue and Red Light Elongates Young Cos Lettuce Leaves and Promotes Growth under High Daily Light Integral

Autor: Tomohiro Jishi, Ryo Matsuda, Kazuhiro Fujiwara

Publikováno v: HortScience, Vol 56, Iss 8, Pp 940-945 (2021)

Cos lettuce was grown under different spectral photon flux density distribution (SPFD) change patterns with blue- and/or red light-emitting diode (LED) irradiation with a 24-hour cycle. Twelve treatments were designed with a combination of four relat

Estimating Light Acclimation Parameters of Cucumber Leaves Using Time-Weighted Averages of Daily Photosynthetic Photon Flux Density

Autor: Liyao Yu, Kazuhiro Fujiwara, Ryo Matsuda

Publikováno v: Frontiers in Plant Science, Vol 12 (2022)

Leaves acclimate to day-to-day fluctuating levels of photosynthetic photon flux density (PPFD) by adjusting their morphological and physiological parameters. Accurate estimation of these parameters under day-to-day fluctuating PPFD conditions benefit

Manipulation of Intraday Durations of Blue- and Red-Light Irradiation to Improve Cos Lettuce Growth

Autor: Tomohiro Jishi, Ryo Matsuda, Kazuhiro Fujiwara

Publikováno v: Frontiers in Plant Science, Vol 12 (2021)

The morphology of plants growing under combined blue- and red-light irradiation is affected by the presence or absence of time slots of blue- and red-light mono-irradiation. The purposes of this study were to investigate the morphology and growth of

Effects of Artificially Reproduced Fluctuations in Sunlight Spectral Distribution on the Net Photosynthetic Rate of Cucumber Leaves

Autor: Ryo Matsuda, Hiroki Ito, Kazuhiro Fujiwara

Publikováno v: Frontiers in Plant Science, Vol 12 (2021)

The effects of photosynthetic photon flux density (PPFD) fluctuations in sunlight have already been investigated; however, the spectral photon flux density distribution (SPD) has hardly been considered. Here, sunlight SPD fluctuations recorded for 20

Gas Exchange Rates Decrease and Leaf Temperature Increases in Nicotiana benthamiana Leaves Transiently Overexpressing Hemagglutinin in an Agrobacterium-Assisted Viral Vector System

Autor: Ryo Matsuda, Akihiro Ueno, Hirofumi Nakaigawa, Kazuhiro Fujiwara

Publikováno v: Frontiers in Plant Science, Vol 9 (2018)

In this study, gas exchange characteristics and temperature of Nicotiana benthamiana leaves transiently overexpressing hemagglutinin (HA), an influenza vaccine antigen, with an Agrobacterium tumefaciens-assisted viral vector were investigated. Inocul
