“…The leaf area and dry weight in successive 10-cm layers from the top to the base (vertical distribution) were measured for six plants of each cultivar on 29 July, 2002. Radiation interception was measured on 26 and 27 July, 2002, with simple integrated solarimeter fi lms (10 mm × 35 mm, 60 mg, Optleaf, Taisei E & L Inc., Japan; Yoshimura et al, 1990). After sunset on 25 July, 30 simple integrated solarimeter fi lms were stuck on the leafl et surface in each 10-cm layer of each cultivar using double-sided binding tape, and they were detached from the leafl ets at night after two days.…”

“…In order to understand the radiation environment of the pneumatophores as the dominant factor of photosynthesis, we measured the solar radiation on both the vertical and horizontal surfaces in the brackish water by using the dye film developed by Yoshimura et al (1990) for the estimation of integrated total solar radiation.…”

The pneumatophores of Avicennia and Sonneratia species photosynthesize and the photosynthetically generated O2 is used for the respiration in the roots in subsoil. To understand the radiation environment of the pneumatophores, we measured solar radiation on the vertical surface (Rv) in the water with dye films. The Rv averaged over the daytime at a depth of 30 cm was similar to the light compensation points in the pneumatophores. From this result, it can be supposed that the photosynthesis nearly compensated the respiration at a depth of 30 cm and supplied O2 to the roots in subsoil at shallower places, even when the pneumatophores were submerged in the daytime.

Distribution of photosynthetic photon flux density (PPFD) in a culture vessel was estimated using a sensor film for measuring the integrated solar radiation. A plantlet model whose leaves were constructed from sensor film was used to simulate a potato plantlet. The plantlet model was put into a culture vessel and, after exposure to culture conditions for 20 days, PPFD was estimated for each individual model leaf based on the degree of fading of the sensor film. The method was able to demonstrate the light intensity distribution patterns inside a small test tube under downward lighting conditions. This technique allows for the estimation of light intensity distribution patterns inside a small culture vessel, which was previously difficult to measure by conventional methods.Abbreviations: PPFD -photosynthetic photon flux density
